Relative Measurement Digital Clamp Multimeter With NCV Zone

Maintenance

1.4.1 Please do not attempt to test lead the shell to adjust or repair instrument, this operation can only be fully understood by technicians
1.4.2 Before test leading the instrument bottom shell and the battery cover, should be removed the test lead from the measured line test lead
1.4.3 In order to avoid false readings may cause electric shock, when the instrument display “” symbol,
The battery should be replaced immediately.
1.4.4 Use a damp cloth and a mild detergent to clean the instrument; do not use abrasive detergents or solvents.
1.4.5 The instrument when not in use should turn off the power,
1.4.6 If you do not use a meter long time, the battery should be removed to prevent damage to the instrument.

3.2.1 AC Current

- Max input:400A AC

- Frequency:50Hz

- When ac current is measured, the meter automatically opens an internal low-pass filter to filter out high-frequency current.

3.2.2 DC voltage

- Input impedance:10MW

- Maximum/ input voltage:600V AC (Effective value)OR 600V DC

3.2.4 AC voltage

-Input impedance:10MW

- Maximum/ input voltage:600V AC (Effective value)or 600V DC

In the small voltage range, the meter pen is not connected to the measured circuit, the meter may have jumping reading, this is normal, because of the high sensitivity of the meter, does not affect the actual measurement results

3.2.5 Resistance

- open-circuit voltage:About 0.4V

- Overload protection:600V DC or AC(Effective value)
