FLUKE 335 clamp meter

[frank cinker]

I just purchased a new FLUKE 335 clamp meter. I of course assume it is accurate. For curiosity sake alone, how can I test it to be sure? I used a 100 ohm resistor to test the ohm tester and it was accurate. How would I test the volts and amps?
Also, how often should I have it professionally recalibrated for accuracy?

Thanks,
Frank

i don't think a resistor would be very accurate. but...maybe you got lucky.
