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

Difference between a Memory HiCorder’s maximum rated voltage to earth and its maximum input voltage

QIn the specifications for a Memory HiCorder input unit, a maximum rated voltage to earth as well as a maximum input voltage are listed. What is the difference between these two characteristics?

A

Measurement of the secondary side of an inverter

QWhat type of instrument should I use to measure an inverter’s current and voltage?

A

What is the filter function?

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

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

The polarity (+/-) was reversed when I made a measurement using the resistance range. Is the instrument broken?

QI have a question about an analog tester. The polarity (+/-) is reversed when performing measurements with the resistance range. Why is this? Wouldn’t this invite mistakes, for example when checking diode polarity?

A

Infrared thermometer measurable temperature range

QHow far away can an infrared thermometer take readings?

A

Clamp sensor voltage to earth

QThe specifications for the Clamp On Leak HiTester 3283 indicate a maximum rated voltage to earth of 300 V rms AC (insulated conductor) (CAT III, 300 V). Can the 3283 be used to measure a 3-phase 400 V circuit?
