3.1.5
Upper 5 digit LCD display
The 5 digit LCD display is a multi-function display, the functions are described below:
Normal mode :
There is a 5 digit DVM display, display measuring data of the DC input terminal or V-
sense input terminal if V-sense AUTO is programmed, or the 5 digit voltage meter
displays the voltage of V-sense input terminal if V-sense ON is programmed.
When the auto-sense of V-sense function is programmed, the auto-sense circuit of
33501 series electronic load can check the V-sense cable is connected or not, the V-
sense BNC input is detected if it is greater than 0.5V (33501, 33511) or 2.5V (33521)
or not, if yes then the 5 digit DVM measures the sense BNC input, otherwise, the 5
digit DVM measures the DC input terminals of the load module.
