Voltage Measurement - Textron GREENLEE CM-1360 Manuel D'instructions

1.800.544.2843
Typical Measurements and Accuracy
Refer to the "Specifications" section for operating conditions and temperature coefficient.
Accuracy is specified as follows: ± (a percentage of the reading + a fixed amount) at 23 °C ± 5 °C
(73.4 °F ± 9 °F).
Frequency must be within the specified bandwidth for non-sinusoidal waveforms. Crest factors, unless
otherwise specified, are as follows:
• Crest factor < 2.5:1 at full scale
• Crest factor < 5.0:1 at half scale
