Safety Information

Understand and follow operating instructions carefully

WARNING

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
Always use proper terminals, switch position, and range for measurements.
To reduce the risk of fire or electric shock, do not use this product around explosive gas or in damp locations.
Verify the Meter operation by measuring a known voltage. If in doubt, have the Meter serviced.
Do not apply more than the rated voltage, as marked on Meter, between terminals or between any terminal and earth ground.
To avoid false readings that can lead to electric shock and injury, replace battery as soon as low battery indicator blinks / appears.
Avoid working alone so that assistance can be rendered.
Do not use the Tester if the Tester is not operating properly or if it is wet.
Individual protective device must be used if hazardous live parts in the installation where the measurement is to be carried out could be accessible.
Disconnect the test leads from the test points before changing the position of the function rotary switch.
Never connect a source of voltage when the function rotary switch is not in voltage position.
When using test leads or probes, keep your fingers behind
the finger guards.
Use caution with voltages above 30Vac rms, 42 Vac peak, or 60Vdc. These voltages pose a shock hazard.
Remove test lead from Meter before opening the battery door or Meter case.
DO NOT USE the test leads when the internal white insulationlayer is exposed.
DO NOT USE the test leads above maximum ratings of CAT. Environment, voltage and current, that are indicated on the probe and the probe tip guard cap.
DO NOT USE the test leads without the probe tip guard cap in CAT III and CAT IV environments.
Probe assemblies to be used for MAINS measurements shall be RATED as appropriate for MEASUREMENT CATEGORY III OR IV according to IEC 61010-031 and shall have a voltage RATING of at least the voltage of the circuit to be measured.
Only replace the blown fuse with the proper rating as specified in this manual.
Do not attempt a resistance measurement when the open voltage is above the fuse protection rating. Suspected open voltage can be checked with voltage function.
Never attempt a voltage measurement with the test lead inserted into the Ω input terminal.
Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, or capacitance.

Measuring ACV/DCV : Auto sense function

Auto Sense Function

Auto sense mode: The meter displays ACV or DCV whichever is higher (>1V).
If the measured voltage is above 660Vac/dc, “> 660Vac/dc” will appear on the display

WARNING

When connecting the test leads to the DUT (Device Under Test) connect the common test leads before connecting the live leads; When removing the test leads, remove the test live leads before removing the common test leads.
Don’t apply more than AC/DC 600V between the V-COM terminals.

Measuring Capacitance

Wireless Link

The meter uses Bluetooth low energy (BLE) V5.0 wireless technology to download the stored data. The open-air communication range is up to 6m. Download “APPA Connect” App via the following QR Code. Turn on LINK function of the meter and open “APPA Connect” to connect the DMM. The LINK icon of the meter will freeze on LCD after the connection establishes successfully.

WARNING

Do not use the High Frequency Rejection (Low Pass Filter) to verify the presence of hazardous voltages. Voltages greater than what is indicated may be present. First, make a voltage measurement without the filter to detect the possible presence of hazardous voltage. Then select the filter function.

Measuring Earth-Bond Resistance (Continuity)

Earth-Bond Resistance

Before starting the test :
(a) The circuit under test must be completely de-energized.
(b) Check the fuse is good. See the chapter “Testing the fuse”.
(c) Short the test leads before measurement, and press the Function button to zero the wire resistance of probe. If the wire resistance is <10Ω, the resistance offset value will be saved, and the “->0<-” symbol will be displayed on LCD
Lock mode :
Press the Lock button to enter the Lock Mode. Then press the TEST button to start the test. The test voltage will continue to be applied until the TEST/LOCK button is pressed again.
The meter displays the ” ＞ ” symbol and the maximum resistance for the range when measured resistance is higher than the maximum display range.

Measuring Insulation Resistance

Wireless Link

Before starting the test :
The circuit under test must be completely de-energized. If the voltage detected is above 30V, “>30V” will appear on the display. In this condition, the test is inhibited.
Press the Function button to display insulation resistance or Leakage current during the test or when the test stops.
Lock mode: Press the Lock button to enter the Lock Mode. Then press TEST button >1sec to start the test. The test voltage will continue to be applied until the TEST/LOCK button is pressed again.
Stop the output test voltage before removing the test leads (to enable the tester to discharge capacitive circuits). If the screen displays volts, wait until it reaches zero.
The meter displays the ” ＞ ” symbol and the maximum resistance for the range when measured resistance is higher than the maximum display range.

Using the Compare function

Compare Function

Before starting the Insulation Resistance test, select the comparative value in Setup mode: 0.5MΩ, 10MΩ, 20MΩ, 50MΩ, 100MΩ, 200MΩ, 500MΩ, 1000MΩ.

Before starting the Earth-Bond Resistance test, select the comparative value in Setup mode: 0.5Ω, 1Ω, 2Ω, 3Ω, 4Ω, 5Ω, 10Ω, 20Ω, 30Ω, 40Ω.

If the measured value is better than the selected compare value, the Pass indicator will be green, otherwise it is red.

Measuring PI/DAR/Timer

Switch Auto Voltage sense

Press TEST button to start/interrupt the PI/DAR test.
Press Function button during the PI/DAR test to switch display the output voltage / leakage current / the time left of the test.

PI(Polarization Index)=R10-min/R1-min
DAR(Dielectric Absorption Rations)=R1-min/(R30-sec or R15-sec)
Timer : Countdown timer

R10-min : the insulation resistance measured at the 10 minute after pressing the TEST button.
R1-min : the insulation resistance measured at the 1 minute after pressing the TEST button.
R30-sec : the insulation resistance measured at the 30 seconds after pressing the TEST button.
R15-sec : the insulation resistance measured at the 15 second after pressing the TEST button.

NOTE: R30-sec or R15-sec can be set in setup mode
NOTE: Countdown time interval can be set in setup mode

If the reading for DAR is bigger than 1.3 or PI is bigger than 2, it indicate a good insulation quality.

When the measured resistance is higher than the maximum range, the screen will display “Err” symbol for PI/DAR value.
