Electrical Specifications
Accuracy is given as ±(% of r counts of
least significant digit) at 23°C ± 5°C, with relative
humidity Less than 80% R.H. Accuracy is specified
for a period of one year after calibration.
1. Temperature coefficient
0.15 x (Specified accuracy) / °C , < 18°C , > 28°C
2. AC Function
ACV and ACA specifications are ac coupled, true
R.M.S. The crest factor may be up to 3.0 as 4000
counts.
For non-sinusoidal waveforms, Additional
Accuracy by Crest Factor (C.F.) :
Add 3.0% for C.F. 1.0 ~ 2.0.
Add 5.0% for C.F. 2.0 ~ 2.5.
Add 7.0% for C.F. 2.5 ~ 3.0.
There is a little rolling less than 10 digits in Auto AC &
DC Test Mode when measuring AC signal.
