| measurement accuracy |
[In slow mode, with a range of 10 m Ω and an average of 16 settings]
±0.060 % rdg. ±0.001 % f.s. |
| test current |
[10 m Ω range] 1A DC~[1000 Ω range] 1 mA DC |
| Open port voltage |
Maximum 20V DC note: The current mode is set to PULSE, and the connection improvement is set to OFF/PULSE. The voltage in the unmeasured state is below 20mV (measured together with a 10M Ω voltmeter) |
| sampling rate |

| Merge time |
[10m Ω range, default value] Fast 2.0ms, Medium 5.0ms, Slow 1PLC
Set range: 0.1ms~100.0ms, or 1-5 PLCs (at 50 Hz), 1-6 PLCs (at 60 Hz)
Note: PLC=one power line cycle (main waveform cycle)
