Remarks:
[1] Specifications are for 0.5 Hour warm-up, “Slow” measurement rate and calibration
temperature 18℃~28℃.
[2] 10% over range on all ranges except for DCV 1000 V, ACV 750 V, DCI 10 A and ACI
10 A.
[3] Specifications are for amplitude of sine wave input > 5% of range. For inputs from 1%
to 5% of range and < 50 kHz, add 0.1% of range extra error. For 50 kHz to 100 kHz,
add 0.1% of range extra error.
[4] Plus 0.025 V of error per 1 V after the first ± 400 VAC.
[5] Specifications are for sine wave input > 5% of range. 0.1% errors will be added when
the range of input sine wave is 1% to 5%.
[6] 30 seconds OFF after 30 seconds ON is recommend foe the continuous current that
higher than DC 7 A or AC RMS 7 A.

Remarks:
[1] Specifications are for 0.5 Hour warm-up.
[2] Except for special marks, the AC input voltage is 5% to 110% of range when <100 kHz
and 10% to 110% of range when >100 kHz. 750 V range is limited to 750 Vrms.
The accuracy is 10 times % of Reading when the measurement range of AC voltage is
in 600mV range.
