[ 1, 3 ]
Additional Errors ( % of reading )
[3]
[ 1 ] Specifications are for 90 minute warm–up, using 1 second aperture.
[ 2 ] Relative to calibration standards.
[ 3 ] For AC input voltages 10% to 120% of range except where noted. 750 V range limited to 750 Vrms.
100 mV range specifications are for full scale or greater inputs. For inputs from 10 mV to 100 mV,
multiply total % of reading error by 10.
Trans fe r Accuracy ( typical ) 0.0003% of reading
Conditions: - Within 10 minutes and ± 0.5 °C.
- Within ±10% of initial voltage and ± 1% of initial frequency.
- Following a 2–hour warm–up.
- For inputs > 1 kHz and > 100 mV
- Using 1 second gate time
- Measurements are made using accepted metrology practices.
