Notes:
[1] Specifications are for 60 minute warm–up and set reading resolution as 5½ and calibration
temperature between 18 ℃ and 28 ℃.
[2] 20% over range on all ranges, except DCV 1000V, ACV 750V, DCI and ACI 10A range.
[3] Specifications are for sine wave input >5% of range. For inputs from 1% to 5% of range and
<50 kHz, add 0.1% of range additional error. For 50 kHz to 100 kHz, add 0.13% of range.
750Vac range limited to 100 kHz or 8x10
7
Volt-Hz.
[4] Specifications are for sine wave input >5% of range. Add 0.1% of the range for the sine wave
input is 1%~5% of the range.
[5] For current terminal, > 7A DC or ACRMS for 30 seconds ON and 30 seconds OFF.
