Simple question - how often should multimeters be calibrated? Annually? 3 year?

eBay one or decent fluke type

Does this affect the calibration period?

Depends if your buying Chinese stuff which don't give you correct readings

We purchased a calibration test kit and test our own meters for calibration yearly, and we by a new meter each year with a calibration certificate to test our meters against. 

The old meters we test for calibration and then use them as spares or replacement for failed meters.

old ACT stuff was TES of Taiwan,

 

Currently have a Martindale which quite nice (which I think is BRK precision)

 

Cheapest I'd go is Temma or Uni-Trend, below that whats the point ?

I’ve had a Fluke 179 multimeter for 9 years, still going now, one fuse replacement after a colleague borrowed. Awesome investment

 

also got Fluke 1653 multi function tester.

Worth the money

Master (office held) meter only needs to be calibrated every two years, save yourself some money.

Office held meter which you check issued meters against yearly only needs to be done every 2yrs, that's what the NSI say
