Hi anyone,

please help me, i'm a testing enginer on my company.
usually for Power meter we send it to supplier for calibration it.
but my boss suddenly order me to find way to calibration it inhouse.

Power Meter Model Hm8115-2 (Hameg)
we have Multimeter Fluke 45 for measure the Voltage and Current.

but i confused, what other item that i must have ( Like Load, Resistor Etc ) and procedure to calibration Power Meter.

Please someone help me.

Please remember the people who visit here and help are volunteers. Hopefully someone will be able to help, but help isn't necessarily within a few hours. Sometimes it is, but not usually. It also may be that no one who is visiting right now has that same instrument so no one can answer.

Have you asked your equipment supplier for their calibration procedure? You never know - They might help you. And have you looked through the instrument manual? Just a couple of thoughts off hand.

Most power meter calibrations I've seen are a comparison: one power to another.

Why the push to do in-house? I would submit it's less expensive and better quality to send the power meter to a competent lab for calibration.

Also check sources like
SGS Indonesia
Yokogawa
TUV - Nord
Kawan lama
Batam
Yamamoto
Siwali
PT CALTESYS
mmasa.com

This would be better than in house for the type of power meter you detail.....

hi Mark, i already reading the manual and ask the manufacture but they said. it will be company privacy.

hi Bradm, my boss tel me of course for safe the cost and he want to make own calibration lab for long-term.
as i know, the third supplier just comparing/proving the instrument reading is in the tolerance. but if the reading is out of tolerance, they cannot adjust the reading.

thanks all, but i hope there's some one, who can help me.

best regards
agus

The closest I can recommend is sending it out for calibration to a calibration lab (not the manufacturer) and requiring a copy of their calibration procedure for the instrument in addition to the calibration certificate. You *might* be able to get a cal procedure that way.

hi marc, yaa that's right. but i little confused to generate AC current for calibration it, we have AC power supply 5kVA, Vmax = 300V Imax = 40 A. how to generate AC current with AC Power supply. what kind/spesification of Load/resistor that i must using on?
