KEY# Description

The 5 digit LCD display is a multi-function display, the functions are described below:
Normal mode:
This is a 5 digit DVM display, measuring data of the DC input terminal or V-sense input terminal if V-
sense AUTO is programmed. If V-sense ON is programmed, the display shows the voltage at the V-
sense input terminal only.
When the auto-sense of V-sense function is programmed, the auto-sense circuit of the electronic
load can check if the V-sense cable is connected, If the V-sense input detected is greater than 0.7V
(e.g. 5L12-24,) or not. If both conditions are true, the 5 digit DVM measures at the sense input
(remote V sense); otherwise, the 5 digit DVM measures at the DC input terminals of the load (local V
sense).
Test Setting Mode:
Short: Short test Enable and Short Setting programming
:
Display will show: “Short”.
OPP: OPP test Enable and OPP Setting programming
:
Display will show: ”OPP”.
OCP: OCP test Enable and OCP Setting programming
:
Display will show: ”OCP”.
During Short, OCP and OPP test programming, this display will show sensed voltage or load Input
voltage.

This readout can be in one of two modes: Normal or Setting mode.
In “Normal” mode, this 5 digit LCD displays the measured current of the DC load when the load is
ON.
In “Setting” mode, this LCD displays the following setting parameters. The rotary knob is used to
scroll through these settings:
1.
Config ON programming: Display will individually show ”SENSE”, “LDon”, “LDoFF” and
“POLAR”.
2.
Limit ON programming: Display will individually show ”V_Hi”, “V_Lo”, “I_Hi”, “I_Lo”,
“W_Hi”, “W_Lo” and “NG”.
3.
DYN setting ON programming: Display will individually show ”T-Hi”, ”T-Lo”, ”RISE” and
“FALL”.
4.
Short setting programming: Display will individually show “TIME”, “V-Hi” and “V-Lo”.
5.
OPP setting programming: Display will individually show “PSTAR”, “PSTEP”, “PSTOP” and
“VTH”.
6.
OCP setting programming: Display will individually show “ISTAR”, “ISTEP”, “ISTOP” and
”VTH”.
During Short testing: Display shows the actual load current, the unit is "A".
During OCP testing: Display shows the actual load current, the unit is "A".
During OPP testing: Display shows the actual power, the unit is "W".
When over current protect is tripped: Display shows [OCP].
