Accuracy
See the Specifications section for operating conditions and temperature coefficient.
Accuracy is specified as follows: ± (a percentage of the reading + a fixed amount) at
• 18 °C to 28 °C (64 °F to 82 °F) for voltage and resistance measurements
• 21 °C to 26 °C (70 °F to 79 °F) for current measurements
• 0% to 80% relative humidity

* CM-700 is average sensing, RMS calibrated.
** CM-750 is true RMS sensing. Accuracy is specified for sine waves at full scale and non-sine
waves below half scale. For non-sine waves, add the following crest factor corrections:
• Crest factor 1.4 to 2.0, add 1.0%
• Crest factor 2.0 to 2.5, add 2.5%
• Crest factor 2.5 to 3.0, add 4.0%
