SEFRAM MW 3390 Notice D'utilisation page 28

Shock vibration :
Sinusoidal vibration per MIL-T-28800E
(5 ~ 55 Hz, 3g maximum).
1-3 Electrical Specifications
Accuracy is ±(% reading + number of
digits) at 23°C ± 5°C < 80%RH.
Temperature coefficient :
Add 0.2 x (Specified accuracy) / °C, < 18°C,
> 28°C .

Overload protection :
750Vrms//1000Vdc
Input impedance :
1MΩ // less than 100pF.
AC Conversion Type :
3390 : AC Conversion are average sens-
ing rms indication calibrated to the rms
value of a sine wave input.
3395 :
*1 : Reading less than 15% of full scale
(4000 digits) is needed to add 4 digits and
the settling time will increase.
*2 : AC Conversions are ac-acoupled, true
rms responding, calibrated to the rms
value of a sine wave input. Accuracies are
given for sine wave at full scale and non-
sine wave below half scale. For non-sine
wave add the following Crest Factor
corrections :
