Electrical Specifications - SEFRAM 7352B User Manual

Electrical Specifications


Accuracy is ± (% of reading + number of digits) at 18°C to
28°C (< 80% RH)

For specifications in the 4¾ -digit mode, multiply the number
of digits by 10.

For the best measurements, with relative (Δ) mode to
compensate for offsets.
