3.2 Electrical characteristics
Accuracy is given as ± (measurement error + display error) and applies at 23°C ±5°C and less than 70% RH.
Measurement error (%) is given as a percentage of the current measurement.
Display error (D) is given in units equal to the smallest increment able to be shown on the display.

Conversion of a.c. voltages : 203:
The accuracy specified is for full-scale deflection for sinusoidal voltages and half-scale deflection for non-sinusoidal voltages,
of frequencies less than 500Hz and crest factors of up to 2.

205:
Measurements are a.c. voltage coupled and represent a true r.m.s. value. Calibration
is to the r.m.s. value of a sinusoidal a.c. voltage.
