current measurement, Clamp scaling, Resistance measurement (200
Ω to 2 00 kΩ range), Low-power resistance measurement (2/20 kΩ
range), Continuity test, Diode test
*: With the FAST sampling period set, the unit performs a calibration every
30 minutes for a period of 65
10 ms.
(2) Resistance (2 MΩ range), Low-power resistance (200 kΩ/2 MΩ range)
*: With the FAST sampling period set, the unit performs a calibration every
30 minutes for a period of 65 10 ms.
(3) Resistance (20 to 100 MΩ range)
*: With the FAST sampling period set, the unit performs a calibration every
30 minutes for a period of 65 10 ms.
(4) Frequency measurement gate time
Measurement time: Twice the gate time-input signal period.
