Checking Input Range

The Input Range screen is displayed by pressing the CkRng key on the Scope mode 

screen. Input Range shows the detected range for all channels. The number after the 

status shows the percentage of the input of the instrument’s full range.

The input range can only be viewed, not changed. Press OK when done viewing the 

input range.

The following table describes the messages that may register on the Input Range 

screen. The instrument is able to detect the input range for voltage and current channels 

A, B, C, and D.

If input range is OVER, UNDER, or CLIP, then the rms readings will not be accurate. 

Using CTs below 10% of Full Scale may also cause inaccuracies in amplitude, phase 

and harmonic distortion readings.
