3.2.2 DC voltage
| Range | Resolution | Accuracy |
| 6V | 0.001V | ±(0.5% of reading + 5 words) |
| 60V | 0.01V |
| 600V | 0.1V | ±(0.8% of reading + 5 words) |
- Input impedance: 10MΩ
- Maximum input voltage: 600V DC or 600V AC (rms)
Note:
In the small voltage range, the pen is not connected to the circuit
under test, the instrument may have beating the reading,
This is normal, this is because the instrument caused by high
sensitivity, does not affect the actual measurement results.
