The PD230SRD / PD440S / PD440SRD / PD440SRDX / PD690S /

PD690SRD are portable battery-powered proving units for testing of contact- type voltage detectors or other units with voltage detection capability, e.g. multimeters or multifunction testers. The table below shows the differences in the output voltage for each model .

After the voltage detector probes are pushed down onto the Proving Device (PD) unit output voltage terminals, the PD unit outputs voltage level(s) for period(s) indicated in the table before the voltage drops to 0V and the terminal’s output goes into low impedance mode

PD440S / PD690S

The PD440S and PD690S output a fixed AC voltage for 5s before the output voltage is reduced to 0V and the terminal output goes into low impedance mode.
The PD440S fixed output voltage is 440V AC 50Hz nominal. The PD690S fixed output voltage is 690V AC 50Hz nominal.

PD230SRD / PD440SRD / PD440SRDX / PD690SRD
The output voltage can be set to be to AC or DC mode using the AC/DC output selection push button. The output voltage reduces in steps over a period of 10s.

For example, the PD230SRD outputs voltage in the following steps: 230V for 4s, 120V for 2s, and 50V for 4s before the output voltage is reduced to 0V and the terminal output goes into low impedance mode.

Battery Installation
Refer to Section 4.1 (Battery Replacement) for the battery installation instructions for all units.

OPERATION

Caution Always make sure the precautions and limitations of the unit being tested are observed. If necessary refer to the specification of the unit being tested. Also refer to the graph of typical output voltage under various load conditions at the rear of these instructions.

AC / DC output voltage mode selection and mode indication
AC / DC output voltage mode selection and mode indication can be carried out using the AC / DC output selection push The push button functions are described below.

Function	Operation step/s	Description

Output mode indication

|

1. Momentarily press the push button while the proving device is not being used

| Output mode indications are as follow, AC output mode – “AC” LED ON,

“DC” LED OFF

DC output mode – “DC” LED ON, “AC” LED OFF

The LED will time out after approximately 10s. It is not necessary to wait for the LED to time out before proving a voltage indicator. If the LED is left to time out, then a minimum of 3s is required before pressing the button again or proving a voltage indicator.

1. Carry out “Output

| 1. Each time the push button is momentarily pressed the Output Mode changes to the opposite mode

2. The default startup output mode does not change

If the LED fails to flash then this indicates that default output mode is already set

to the mode indicated by the “AC” or “DC” LED

The previous table shows the LED indicators for each PD product type.

For example, the PD690SRD includes the following LED indicators- 690V, 440V, 230V, 120V, 50V.

Battery low indication
All PD products support the battery low LED, which is illuminated when the battery voltage is low.

PD440S / PD690S
On these PD products the “High voltage” LED is ON when the live voltage is present at the voltage output terminals. If the loading impedance of the voltage indicator (at the output terminals) is less than 1kΩ then the “High voltage” LED will start flashing.

PD230SRD / PD440SRD / PD440SRDX / PD690SRD
On these PD products there are multiple LED to indicate the voltage at the PD output terminals when a voltage indicator is under test at the terminals. Refer to the graph of typical output voltage under various voltage indicator load conditions on the specification page. Also refer to the “PD Output voltages table” under section 2.2. The LED indication will depend on the loading impedance of the voltage indicator under test as well as the PD output voltage steps in the “PD Output voltage table”. If the loading impedance of the voltage indicator (at the output terminals) is less than 1kΩ then the “50V” LED will start flashing.

Voltage Output Mode (AC / DC)
AC LED and DC LED indicate the PD output voltage mode.

Proving a Test Lamp, Voltage Tester / Indicator, DMM etc
Place one probe of the unit under test into the right hand socket of the proving unit until it makes contact with the terminal. Place the other probe into the left hand terminal of the proving unit and gently press It is important to follow this procedure in order to ensure PD output voltage is applied to the equipment under test from the start of the PD output voltage test cycle.
The PD output voltage test cycle starts from when the voltage indicator is applied to the left hand terminal of the PD.
On the PD440S and PD690S, the output voltage test cycle is 5s long.
On the PD230SRD / PD440SRD / PD440SRDX / PD690SRD, the output voltage test cycle is up to 10s long.
At the end of these PD units’ test cycles, the output voltage drops to 0V and the output goes into low impedance. For SRD and SRDX versions, a minimum of 3s is required between tests.
Observe that the required indicators on the unit under test illuminate, then withdraw the probe from the right hand terminal first, and then the left.
If none of the proving unit LED’s illuminate when performing the above tests, check the condition of the proving unit batteries and replace them if required (see section 4.1).

Test Lamp, Voltage Tester / Indicator Cables
During the above tests, emphasis should also be placed upon the flexing of the UUT cable along its length, and particularly at the entry points to the hand held elements, to confirm that the cable has not fractured. It may be necessary to perform this test a number of times as the proving unit times out after 5s on the PD440S /PD690S and after 10s on the PD230SRD / PD440SRD / PD440SRDX / PD690SRD.

CALCHECK (PD440SRDX only)
The CALCHECK feature may be used to check that a multifunction tester, insulation tester or continuity tester is maintaining ongoing accuracy between calibrations. There are two insulation test resistance values, 0.5MΩ and 1MΩ. There are also two continuity test resistance values, 0.5Ω and 1Ω.

One probe of the tester being checked should be placed on the desired resistance value and the other probe should be placed on the COM terminal, following the instruction manual for the tester being used. The CALCHECK feature is not designed to be used to check loop testers, where the high test current will damage the proving device. The CALCHECK (X models only) feature can be used as a regular check that instruments are not drifting between calibrations.

Records can be kept using the CALCHECK Verification Measurement sheet at the back of this manual. An initial measurement can be taken soon after calibration and the results recorded. Further checks can be made periodically, e.g. every month, and the results also recorded on the sheet.

Further copies of the sheet can be downloaded from www.martindale- electric.co.uk/manuals/.
