The detector the instrument is using
The parameter the instrument is measuring
The filter the instrument is using
The operating range of the instrument
Detector
The detector determines if the instrument is measuring the running rms
(Root Mean Square) value or the peak value.
If rms is selected then the display shows RMS.
If peak is selected then the disply shows PK.
Depending on the instrument type and the inetegration method selected, the
running rms is calculated as shown below: -
