The various basic functions are selected by turning the function selector switch while the instrument is switched on.

(4) Measuring Adapter

! Attention!
The measuring adapter (2-pole) may only be used together with the test instrument’s test plug. Use for other purposes is prohibited!

The plug-on measuring adapter (2-pole) with the two test probes is used for measurements in systems without earthing contact outlets, e.g. at permanent installations, distribution cabinets and all three-phase outlets, as well as for insulation resistance and low-value resistance measurements. The 2-pole measuring adapter can be expanded to three poles for phase sequence testing with the included measurement cable (test probe).

This key has the same function as the key on the test plug.
(10) IN / I Key (at the control panel) The following sequences are triggered by pressing this key, either on the test plug or at the control panel: · Starts the tripping test after measurement of touch voltage for
RCCB testing (IN). · Measurement of ROFFSET is started in the RLO / ZL-N function. · Semiautomatic polarity reversal (see section 10.9)
(11) Contact Surfaces The contact surfaces are located at both sides of the test plug. When the contact plug is grasped in the hand, contact is automatically made with these surfaces. The contact surfaces are electrically isolated from the terminals and from the measuring circuit. In the event a potential difference of greater than 25 V between protective conductor terminal PE and the contact surface, PE is displayed. See “LED Indications, Mains Connections and Potential Differences” on page 17.
(12) Test Plug Holder The test plug with attached plug insert can be reliably secured to the instrument with the rubberized holder.
(13) Fuses The two fuses protect the device in case of overload. Phase conductor L and neutral conductor N are fused individually. If a fuse is defective, and if an attempt is made to perform a measurement which uses the circuit protected by this fuse, a corresponding message appears at the display panel. See section 21.2, “Fuse Replacement”, on page 97.

(5) Plug Insert (country-specific)
! Attention!
The plug insert may only be used together with the test instrument’s test plug. Use for other purposes is prohibited!
After the plug insert has been attached, the instrument can be directly connected to earthing contact outlets. There’s no need to concern yourself with poling at the plug. The instrument detects the positions of phase conductor L and neutral conductor N and automatically reverses polarity if necessary. The instrument automatically determines whether or not both protective contacts in the earthing contact outlet are connected to one another, as well as to the system protective conductor, for all types of protective conductor measurements when the plug insert is attached to the test plug.
(6) Test Plug The various country specific plug inserts (e.g. protective contact plug insert for Germany or SEV plug insert for Switzerland) or the measuring adapter (2-pole) are attached to the test plug and secured with a threaded connector. The controls on the test plug are subject to interference suppression filtering. This may lead to slightly delayed responses as opposed to controls located directly on the instrument.
(7) Alligator Clip (plug-on)
(8) Test Probes The test probes comprise the second (permanently attached) and third (plug-on) poles of the measuring adapter. A coil cable connects them to the plug-on portion of the measuring adapter.

(14) Holders for Test Probes (8)
(15/16) Current Clamp Connector Only the current clamp transformers offered as accessories may be connected to these sockets.
(17) Probe Connector Socket The probe connector socket is required for the measurement of probe voltage US-PE, earth electrode voltage UE, earthing resistance RE and standing surface insulation resistance. It can be used for the measurement of touch voltage during RCD testing. The probe is connected with a 4 mm contact-protected plug. The instrument determines whether or not the probe has been properly set and displays results at the display panel.
(19) USB Port The USB port allows for the exchange of data between the test instrument and a PC.
(20) RS 232 Port This port allows for data entry by means of a barcode scanner or an RFID reader.
(21) Charging Socket Only the Z502R charger for charging batteries inside the test instrument may be connected to this socket.
(22) Battery Compartment Lid ­ Replacement Fuses
! Attention!
Before removing the lid is removed, the instrument must be disconnected from the measuring circuit at all poles!

MAINS/NETZ LED This LED is only functional when the instrument is switched on. It has no function in the voltage ranges UL-N and UL-PE. It lights up green, red or orange, or blinks green or red depending upon how the instrument has been connected and the selected function (see also section 6.4, “LED Indications, Mains Connections and Potential Differences”, beginning on page 17). This LED also lights up if line voltage is present when measuring RISO and RLO.
UL/RL LED This LED lights up red if touch voltage is greater than 25 V or 50 V during RCD testing, as well as after safety shutdown occurs. It also lights up if RISO or RLO limit values have been exceeded or fallen short of.
RCD · FI LED This LED lights up red if the RCCB is not tripped within 400 ms (1000 ms for selective RCDs ­ type RCD S) during the tripping test with nominal residual current. It also lights up if the RCCB is not tripped before nominal residual current has been reached during measurement with rising residual current.

instrument from the measuring circuit (mains) at all poles!

Do not switch the test instrument on during charging.

The charging process may otherwise be impaired.

! Attention!
Commercially available, individual rechargeable or regular batteries must comply with the technical data (see page 10).
Loosen the slotted screw for the rechargeable battery compartment lid on the back and remove the lid.
Remove the depleted battery pack or commercially available rechargeable or regular batteries.
Insert the battery pack or commercially available rechargeable or regular batteries into the battery compartment.
! Attention!
In the case of commercially available, individual rechargeable or regular batteries: make sure that all of the batteries are inserted with correct polarity. If just one battery is inserted with reversed polarity, it will not be recognized by the instrument and may result in leakage from the batteries and damage to the instrument.
Replace the lid and retighten the screw.
Note Dispose of the battery pack or commercially available, individual rechargeable or regular batteries in an environmentally sound fashion when their service life has nearly expired (approx. 80% charging capacity). See section 24, “Disposal and Environmental Protection”, on page 99.

9.1 Creating Distributor Structures, General A complete distributor structure with data for electrical circuits and RCDs can be created in the test instrument. This structure makes it possible to assign measurements to the electrical circuits of various distributors, buildings and customers.
There are two possible procedures: · On location or at the
construction site: create a distributor structure in the test instrument. A distributor structure with up to 50,000 structure elements can be created in the test instrument, which is saved to the instrument’s flash memory.

The test instrument and the PC must be connected with a USB cable in order to transfer structures and data.
Note The rotary selector switch may not be set to the “U” position during data transmission.
The following image appears at the display during transfer of structures and data.

or

· Create and save an image of an existing distributor structure at a PC with the help of ETC report generating software (Electric Testing Center) ­ see Help > Getting Started (F1). The distributor structure is then transferred to the test instrument.

10 General Information on Measurements

10.1 Using Cable Sets and Test Probes · Scope of delivery: 2-pole measuring adapter and cable for
expansion into a 3-pole adapter (PRO-A3-II/) · Optional accessory: PRO-RLO II (Z501P) 2-pole measuring
adapter with 10 m cable · Optional accessory: KS24 cable set (GTZ3201000R0001) Measurements per DIN EN 61010-031 may only be performed in environments in accordance with measuring categories III and IV with the safety cap attached to the test probe at the end of the measurement cable. In order to establish contact inside 4 mm jacks, the safety caps have to be removed by prying open the snap fastener with a pointed object (e.g. the other test probe).
! Attention!
Grip and hold the test plug and test probes securely when they have been inserted, for example, into a socket. Danger of injury exists if tugging at the coil cord occurs, which may cause the test plug or test probes to snap back.
10.2 Test Plug ­ Changing Inserts The test plug can be fitted with various inserts (e.g. two-pole measuring adapter or country-specific plug insert). In order to change inserts, unscrew the retaining ring until you can pull out the currently used insert. Then mount the desired insert and retighten the retaining ring. (See overview in section 5.4 on page 8.)
10.3 Connecting the Instrument For systems with earthing contact sockets, connect the instrument to the mains with the test plug to which the appropriate, country-specific plug insert is attached. Voltage between phase conductor L and protective conductor PE may not exceed 253 V! Poling at the socket need not be taken into consideration. The instrument detects the positions of phase conductor L and neutral conductor N, and automatically reverses polarity if necessary. This does not apply to the following measurements:

The measurement is interrupted automatically, or the measuring sequence is blocked (except for voltage measuring ranges and phase sequence testing) in the event of: · Impermissible line voltages (< 60 V, > 253 V / > 330 V /

440 V or > 550 V) for measurements which require line voltage · Interference voltage during insulation resistance or low resistance measurements · Overheating at the instrument As a rule, excessive temperatures only occur after approximately 50 measurement sequences at intervals of 5 seconds, when the rotary selector switch is set to the ZL-PE or ZL-N position. If an attempt is made to start a measuring sequence, an appropriate message appears at the display panel. The instrument only switches itself off automatically after completion of an automatic measuring sequence, and after the predetermined on- time has expired (see section 7.2). On-time is reset to its original value as defined in the setup menu, as soon as any key or the rotary selector switch is activated. The instrument remains on for approximately 75 s in addition to the preset on-time for measurements with rising residual current in systems with selective RCDs. The instrument always shuts itself off automatically!
10.5 Measured Value Display and Memory The following items appear at the display panel: · Measured values with abbreviations and units of measure · Selected function · Nominal voltage · Nominal frequency · Error messages Measured values for automatic measuring sequences are stored and displayed as digital values until the next measurement sequence is started, or until automatic shutdown occurs. If the upper range limit is exceeded, the upper limit value is displayed and is preceded by the “>” symbol (greater than), which indicates measurement value overrun.

­ Voltage measurement in switch position U ­ Insulation resistance measurement ­ Low-resistance measurement The positions of phase conductor L and neutral conductor N are identified on the plug insert.

Note The depiction of LEDs in these operating instructions may vary from the LEDs on the actual instrument due to product improvements.

If measurement is to be performed at three-phase outlets, at dis- Testing Earthing Contact Sockets for Correct Connection

tribution cabinets or at permanent connections, the measuring adapter must be attached to the test plug. Connection is established with the test probes: one at PE or N and the other at L.

The testing of earthing contact sockets for correct connection prior to protective measures testing is simplified by means of the instrument’s error detection system.

The 2-pole measuring adapter must be expanded to 3 poles with the included measurement cable for the performance of phase sequence testing. Touch voltage (during RCCB testing) and earthing resistance can be, and earth-electrode potential, standing surface insulation resistance and probe voltage must be measured with a probe. The probe is connected to the probe connector socket with a 4 mm contact-protected plug.

The instrument indicates improper connection as follows: · Impermissible line voltage (< 60 V or > 253 V):

12 Testing RCDs

The testing of residual current devices (RCDs) includes: · Visual inspection · Testing · Measurement Use the test instrument for testing and measurement.
! Attention!
When testing systems with RCCBs, they may switch off. This may occur even though it’s not normally provided for by the test. Leakage currents may be present which, in combination with the test current of the test instrument, exceed the shutdown threshold value of the RCCB. PCs which are operated in proximity to such RCCB systems may switch off as a consequence. This may result in inadvertent loss of data. Before conducting the test, precautions should therefore be taken to ensure that all data and programs are suitably backed up and the computer should be switched off, if necessary. The manufacturer of the test instrument assumes no liability for any direct or indirect damage to equipment, computers, peripheral equipment or data bases when performing the tests.
Measuring Method The following must be substantiated by generating a fault current downstream from the RCD: · That the RCD is tripped no later than upon reaching
its nominal fault current value · That the continuously permissible touch voltage value
UL agreed upon for the respective system is not exceeded This is achieved by means of: · Touch voltage measurement
10 measurements with full-waves and extrapolation of IN
I—3–N-

· Substantiation of tripping within 400 ms or 200 ms with IN

IN

(measurement up to 1000 ms)

ta · Substantiation of tripping current with rising residual current
This value must be between 50% and 100% of IN (usually about 70%).

Test Standard The following must be substantiated per IEC 60364-6: ­ Touch voltage occurring at nominal residual current may not
exceed the maximum permissible value for the system. ­ Tripping of the RCCB must occur within 400 ms (1000 ms for
selective RCDs) at nominal residual current.

Important Notes
· The test instrument permits simple measurements at all types of RCDs. Select RCD, SRCD, PRCD etc.
· Measurement must be executed at one point only per RCD (RCCB) within the connected electrical circuits. Low-resistance continuity must be substantiated for the protective conductor at all other connections within the electrical circuit (RLO or UB).
· The measuring instruments often display 0.1 V touch voltage in TN systems due to low protective conductor resistance.
· Be aware of any bias currents within the system. These may cause tripping of the RCDs during measurement of touch voltage UB, or may result in erroneous displays for measurements with rising current: Display = IF – Ibias current
· Selective RCDs identified with an S can be used as the sole means of protection for automatic shutdown if they adhere to the same shutdown conditions as non-selective RCDs (i.e. ta < 400 ms). This can be verified by measuring breaking time.
· Type B RCDs may not be connected in series with type A or F RCDs.

t · No premature tripping with the test instrument, because test-
ing is begun with 30% residual current (if no bias current occurs within the system).

Note
Bias Magnetization Only AC measurements can be performed with the 2pole adapter. Suppression of RCD tripping by means of bias magnetization with direct current is only possible via a country-specific plug insert, e.g. SCHUKO, or the 3pole adapter.

Measurement With or Without Probe
Measurements can be performed with or without a probe. Measurements with probe require that the probe and reference earth are of like potential. This means that the probe must be positioned outside of the potential gradient area of the earth electrode (RE) in the RCD safety circuit. The distance between the earth electrode and the probe should be at least 20 m. The probe is connected with a 4 mm contact-protected plug. In most cases this measurement is performed without probe.

1. Measuring Touch Current Without Tripping the RCD

Measuring Method

The instrument uses a measuring current of only 1/3 nominal

residual current for the determination of occurs at nominal residual current. This

RCCB.

This measuring method is especially advantageous, because touch voltage can be measured quickly and easily at any electrical outlet without tripping the RCCB.

The usual, complex measuring method involving testing for the proper functioning of the RCD at a given point, and subsequent substantiation that all other systems components requiring protection are reliably connected at low resistance values to the selected measuring point via the PE conductor, is made unnecessary.

N-PE Reversal Test Additional testing is conducted in order to determine whether or not N and PE are reversed. The pop-up window shown at the right appears in the event of reversal.
