[1] The bandwidth is 40Hz to 1kHz
[2] When > 10A, accuracy is unspecified and maximum
measuring time is 30 sec.
[3] Below 10% of range, add 2d to accuracy.
[4] Below 10% of range, add 10d to accuracy.
Input Impedance : < 2Ω at mA inputs, < 0.1Ω at A inputs.

[1] For square wave, the accuracy is unspecified.
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.
