load terminal. To ensure measurement accuracy, a remote sense measurement
terminal is provided at load rear board to compensate voltage drop lost in wire.
Remote sense operation: SENSE (+) and SENSE (-) are remote input terminals.
To avoid voltage drop caused by long input wire of load, the remote sense test
allows direct measurement at input terminal source so as to improve
measurement accuracy.
Operation steps of remote sense measurement:
1. Press
[Shift]
+9 keys to enter menu. Operate
key and select
Remote-Sense. Press
[Enter]
key.
2. Select ON and start Sense function. Set load in remote sense measurement
mode.
3. Remote sense measurement is connected. Refer to figure below for
detailed wiring.

External trigger function
When rear board triggering mode is selected, firstly, set the trigger source as
External and the triggering signal is input from the rear board TRIG terminal.
Press
[Shift]
+ 8 keys to enter system menu. Click Right key till Trigger appears
and flicks. Press
[Enter]
to entry and press
to select External. Press
[Enter]
for confirmation. Press
[ESC]
to exit the menu.
When external trigger is selected, the positive and negative TRIG terminals will
generate trigger signal and the low pulse is valid.
Input corresponding to one trigger can be used for triggering dynamic test, LIST
test and auto test.
3.19.3
External analog quantity test
Loading voltage or current of the electronic load can be controlled by EXT PRG
(positive and negative) analog quantity terminals on rear board. Connect 0-10V
adjustable voltage at the EXT PRG terminal to analog input from 0- full range so
as to adjust input voltage and current of load (10V corresponds to voltage or
current of load at full range).

Voltage fault indication
When load is under overvoltage protection or terminal reverse polarity
