3.19.1 Remote sense compensation functions
Under CC, CV, CR or CW mode, if the load consumes large current, a large
voltage drop will be detected in connection line between tested instrument and
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
1. Press
[Shift]
+ 9(Config) keys to enter menu.
2. Operate
key and select Remote-Sense. Press
[Enter]
key.
3. Select ON and start Sense function. Set load in remote sense
measurement mode.
4. Remote sense measurement is connected. Refer to figure below for
detailed wiring.
3.19.2 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.
Set the triggering sources as follows:
1. Press
[Shift]
+ 8(System) keys to enter system menu.
2. Click Right key till Trigger appears and flicks.
3. Press
[Enter]
to entry and press
to select External. Press
[Enter]
for confirmation.
4. 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.
