Danger
Use of instrument in a manual not specifed by the manufactuer may impair safety features/protection provided by the equipment. Read the following safety information carefully before using or servicing the instrument.

• Do not apply more than 600V.
• Do not use the Meter around explosive das vapor or dust.
• Do not use the Meter in a wet environment.
• When using the test leads, keep your figures away from the lead contacts. Keep your figures behind the finger guards on the leads.
• Do not use the Meter with any parts or cover removed.
• When carrying out insulation measurement, do not contact the circuit under test. Warning
• Do not use the Meter if it is damaged or metal part is exposed. Look for cracks or missing plastic.
• Be careful when working above 33V rms, 46.7V ac rms or 70V DC. Such voltages pose a shock hazard.
• Discharge all loading of circuit under test after measuring high voltage.
• Do not change battery when the Meter is in wet environment.
• Place test leads in proper input terminals. Make sure all the test leads are firmly connected to the Meter’s input terminals.
• Make sure the Meter is turned off when opening the battery compartment.

Caution

• When performing resistance tests, remove all power from the circuit to be measured and discharge all the power.
• When servicing the Meter, use only the test leads and power adaptor with the same model or identical electrical specifications.
• Do not use the Meter if the battery indicator (L) shows a battery empty condition. Take the battery out from the Meter if it is not used for a long time.
• Do not use or store the Meter in an environment of high temperature, humidity, explosive, inflammable and strong magnetic field. The performance of the Meter may deteriorate after dampened.
• Soft cloth and mild detergent should be used to clean the surface of the Meter when servicing. No abrasive and solvent should be used to prevent the surface of the Meter from corrosion, damage and accident.
• Dry the Meter before storing if it is wet.

International Electrical Symbols
International symbols on the Meter and in this manual are explained in Table 2.

Battery Saver (Sleep Mode)

Measurement Operation

This section explains how to make measurements.
Press and hold ON/OFF to turn on the Meter, press again to turn off the Meter. The Meter defaults at
500V range and under continuous measurement of insulation resistance when turned on.

Measuring Voltage
Figure 4. Voltage Measurement

Operating Caution

• To avoid harm to you or damage to the Meter, please do not attempt to measure voltages higher than 600V or 600V rms, although readings may be obtained.
• Special care should be taken when measuring high voltage.

To measure voltage, set up the Meter as Figure 4 and do the following:

1. Press DCV or ACV button to select DC voltage or AC voltage measurement
2. Insert the red and green test leads into EARTH and two LINE terminals
3. When measuring DC voltage, if negative voltage is present on the red test lead, “-” symbol will show on the

Note: When voltage measurement has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads away from the input terminals of the Meter.

Measuring Insulation Resistance
Figure 5. Insulation Resistance Measurement

_& Operating Caution

• When performing insulation resistance tests, remove all power from the circuit to be measured and discharge all the power.
• Operating the Meter must be very careful as it outputs dangerous voltage during measurement. Must make sure the tested object is firmed clipped, hands are away from the clips, then press TEST button to output high voltage.
• Do not short circuit the testing leads during high voltages output or test insulation resistance after high voltages output. This kind of incorrect operating may cause sparking and

fire, which damages the Meter and cause personal injury.
Do not measure over 10 seconds when: measuring resistance < 2MO with use of 500V. measuring resistance < SMO with use of 1OOOV. measuring resistance < 1OMO with use of 2500V. measuring resistance < 20MO with use of 5000V.

To measure insulation resistance, set up the Meter as Figure 5 and do the following:

1. Press IR button to select insulation resistance
2. When there is no testing voltage output, press .A. and T button to 500V, 1OOOV, 2500V or 5000V voltage range.
3. When performing insulation resistance tests, remove all power from the circuit to be measured and discharge all the power.
4. Insert the red test lead into two LINE terminals, the black one into GUARD and the green one into
5. Connect the red and green alligator clip to the circuit to be measured, negative voltage outputs from LINE terminal.
6. Choose one of insulation resistance measurement modes shown as below:
