Electrical Specifications for U1211A
Accuracy is given as ± (% of reading + number of least significant digits) at 23 °C ± 5 °C, with relative humidity less than 80 % R.H.
ACV/ ACA specifications are ac coupled, true R.M.S. and are valid from 5 % of range to 100 % of range. The crest factor may be up to
3.0 at full-scale except the 1000 V and 1000 A ranges where these are 1.5 at full scale. For non-sinusoidal waveforms, add (2 % reading +
2 % full scale) typical, for crest factors up to 3.

Notes:
1. Overload protection: 1000 V R.M.S. for circuits < 0.3 A of short circuit current
2. Maximum open voltage: < +3.1 V
3. Instant continuity: Built-in buzzer sounds when resistance is less than 10.0 Ω
4. The accuracy of 400 Ω and 4 kΩ is specified after Relative function, which is used to substrate the test lead resistance and the thermal effect
