[1]Specifications are for sine wave inputs that are greater than 5% range.
[2]Input voltage <300Vrms.
[3]The accuracy of ACV+DCV is equal to ACV’s with 10 more digits added.
* The specifications are guaranteed to an input of 750V. A beeping alarm will go off
when the input value is higher than 750V.
* Input protection of 1000V peak on all ranges.
* AC-coupled true RMS – measures the AC component of the input with up to
400Vdc of bias on any range.

[1] The 500μA range requires an input of >35μA to meet specifications. The
5mA~10A ranges need more than 5% of full scale range to meet specifications.
[2] Input current (5k ~ 20kHz)<330mArms.
[3]The accuracy of ACI+DCI is equal to ACI’s with 10 more digits added.
* The specifications are guaranteed to 10A. A beeping alarm will go off when the
input current being measured is higher than 10A.
