• Operating Caution identifies conditions that the user needs to take extra care during operating the Meter

Danger
Use of an instrument in a manual not specified by the manufacturer 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 gas, 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 measurements, do not contact the circuit under test.
  Warning

• Do not use the Meter if it is damaged or the 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 a circuit under test after measuring high voltage.

• Do not change the battery when the Meter is in a 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 number or identical electrical specifications.

• Do not use the Meter if the battery indicator ( ) 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 being dampened.

• Soft cloth and mild detergent should be used to clean the surface of the Meter when servicing. No abrasive or 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.

Measurement Operation

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

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 in 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 display.
4. 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

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 the TEST button to output high voltage Do not short circuit the testing leads during high voltage output or test insulation resistance after high voltage output. This kind of incorrect operation may cause sparking and fire, which damages the Meter and cause personal injury. Do not measure over 10 seconds when: measuring resistance ＜2MΩ with the use of 500V. measuring resistance ＜5MΩ with use of 1000V. measuring resistance ＜8MΩ with use of 1500V. measuring resistance ＜10MΩ with use of 2500V.

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

1. Press the IR button to select insulation resistance measurement. When there is no testing voltage output, press and button to select the 500V, 1000V, 2500V or 5000V voltage range.
2. When performing insulation resistance tests, remove all power from the circuit to be measured and discharge all the power.
3. Insert the red test lead into two LINE terminals, the black one into GUARD and the green one into EARTH. Connect the red and green alligator clip to the circuit to be measured, negative voltage outputs from the LINE terminal.
