Accuracy - Greenlee CM-600 Instruction Manual

Accuracy

Accuracy is specified as follows: (a percentage of the reading + a fixed amount)
at 23 C 5 C (73.4 F 9 F), 0% - 75% relative humidity.
See the Specifications section for operating conditions.

* Maximum open circuit voltage: 1 V
Continuity
Threshold: Tone sounds if the measured resistance is less than approximately 50 ,
and turns off when greater than approximately 300 .
For the CM-600, AC accuracy is specified for sine waves only.
For the CM-650, accuracy specification applies for waveforms with crest factors less than 2.
• For crest factors from 2 to 3, add 1.4% to accuracy.
• For crest factors from 3 to 4, add 3% to accuracy.
