Current
AC and DC Additional Specications
Input Impedance : < 2Ω at mA inputs, < 0.1Ω at A inputs.
Bandwidth : 40Hz to 10kHz
Minimum Resolution : 10uA
Maximum Measuring Time :
1 minutes at A inputs, 10 minutes at mA inputs.
Rest time is 20 minutes minimum.
The Cut-Off Frequency of HFR: 800Hz (-3dB point)
Attenuation Characteristic of HFR: Approx. -24dB
AC Conversion Type:
The AC conversion type is ac-coupled, true rms responding,
calibrated to the sine wave input. For non-sine wave add the
following Crest Factor corrections:
For Crest Factor of 1.4 to 2.0, add 1.0% to AC accuracy.
For Crest Factor of 2.0 to 2.5, add 2.5% to AC accuracy.
For Crest Factor of 2.5 to 3.0, add 4.0% to AC accuracy.
