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
| Range | Resolution | Accuracy |
| 2A | 0.001A | ±(4.0% + 20) |
| 20A | 0.01A | ±(2.5% + 8) |
| 200A | 0.1A |
| 400A | 1.0A |
- 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
| Range | Resolution | Accuracy |
| 2V | 0.001V | ±(0.8% + 5) |
| 20V | 0.01V |
| 200V | 0.1V | |
| 600V | 0.1V | ±(1.0% + 5) |
- Input impedance:10MW
- Maximum/ input voltage:600V AC (Effective value)OR 600V DC
3.2.4 AC voltage
| Range | Resolution | Accuracy |
| 2V | 0.001V | ±(1.2% + 5) |
| 20V | 0.01V |
| 200V | 0.1V |
| 600V | 0.1V | ±(1.5% + 5) |
-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
| Range | Resolution | Accuracy |
| 200W | 0.1W | ±(0.8% + 3) |
| 2kW | 0.001kW |
| 20kW | 0.01kW |
| 200kW | 0.1kW |
| 2MW | 0.001MW | ±(1.2% + 3) |
| 20MW | 0.1MW |
- open-circuit voltage:About 0.4V
- Overload protection:600V DC or AC(Effective value)
