True RMS Multimeter
RND 355-00003
Electrical Specification
Accuracy is given as ±(% of reading + counts of least significant digit) at 23°C ± 5°C,
with relative humidity Less than 80% R.H.
1. Tem
perature coecient
0.1 x (Specied accuracy) / °C, < 18°C, > 28°C
2. AC Funcon
ACV and ACA specicaons are ac coupled, true R.M.S. The crest factor may be up to
3.0 as 4000 counts. For square wave, Accuracy is unspecied.
For non-sinusoidal waveforms, Addional Accuracy by Cres 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.
