3.2 Technical indicators
Environment temperature:23±5℃ Relative humidity:<75%
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.

| 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 Frequency (Voltage frequency measurement)
| Range | Resolution | Accuracy |
| 9.999Hz | 0.001Hz |
±(0.3% + 5)
|
| 99.99Hz | 0.01Hz |
| 999.9Hz | 0.1Hz |
| 9.999kHz | 0.001kHz |
| 99.99KHZ | 0.01kHZ |
- Overload protection:600V DC or AC(Effective value)

| 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)
3.2.7 Continuity test
| Range | Resolution | Function |
