Is HIOKI’s optional PC card the only one I can use?

QCan I use any company’s PC card in my HIOKI power meter or Memory HiCorder?

A

How do clamp on earth testers make measurements?

QClamp on earth testers measure grounding resistance by clamping the ground line. How do they calculate the resistance value?

A

What is the filter function?

QWhen should the filter function provided by the 3282 and 3293-50 be used?

A

There’s a difference between the measured value and the inverter’s display value.

QI measured the secondary side of an inverter with a 3285 (3284), but the measured value differs from the value displayed on the inverter.

A

3281 peak hold function

QThe 3281 and 3282 also have a peak function. Is it possible to capture the crest value for a rush current as with the 3284 and 3285?

A

Measured values on my insulation resistance meter vary. What might be causing this?

Q

A

The digital insulation resistance meter I’m using displayed “OF.”

QWhat does this mean?

A

New standard for test probes

QI heard that the IEC 61010 international safety standard for measuring instruments has been revised. What has changed?

A

Please tell me about the internal resistance of analog testers.

QThe specifications of the HiTester 3030-10 and Multi Tester 3008 indicate an internal resistance of 20 kΩ/V. Please tell me about the effects of the tester’s internal resistance.

A

Display of measurement data in a format such as “1.05E+02”

QWhen I used Excel to view measurement data recorded onto a PC card with a clamp-on power meter, the voltage U1 was displayed in a format such as “1.05E+02.”
