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.
