Page 3: Safety Warning
1. Safety warnings This instrument has been designed, manufactured and tested according to IEC 61010: Safety requirements for Electronic measuring apparatus, and delivered in the best condition after passed the inspection. This instruction manual contains warnings and safety rules which must be observed by the user to ensure safe operation of the instrument and retain it in safe condition. - Page 4 # DANGER ● Never make measurement on the circuit in which electrical potential to ground over 600V exists. ● Do not attempt to make measurement in the presence of flammable gasses. Otherwise, the use of the instrument may cause sparking, which can lead to an explosion.
- Page 5 ● Stop using the test lead if the outer jacket is damaged and the inner metal or color jacket is exposed. ● Do not rotate the Range switch with the test leads connected to the equipment under test. ● Do not install substitute parts or make any modification to the instrument.

6. Measurement 6-1 AC Voltage Warning Function # DANGER ● Never open the battery compartment cover when making measurement. ● Verify proper operation on a known source before use or taking action as a result indication of the instrument. ● Stop using the test lead if the outer jacket is damaged and the inner metal or color jacket is exposed. -
Page 15: Insulation Resistance Measurement
6-2 Insulation Resistance Measurement # DANGER ● Always test the circuit of equipment to ensure it is surely de-energized before measurement according to the instruction of 6-1. ● Never make measurement on a circuit in which earth potential of 600V or higher exist. - Page 16 ④ Check the circuit under test is not energized as follows. Connect the test probe to the circuit under test and read a voltage value. If the circuit is live, the meter indicates the voltage, the live circuit lamp is lit, and warning buzzer sounds.
