Operating Steps
1. Press Shift and CP key to enter the system utility function menu. Select
“Config” and set trigger mode of the trigger source be “Ext”, then press
Enter to confirm.
2. When using the external trigger mode, the falling edge of the trigger
signal output from the negative and positive trigger terminal can enable
trigger function. The trigger can be used in List, Program, and dynamic
test mode.
Voltage fault Indicating Function
When the load is in overvoltage protection or reverse connection
protection, the VF terminal which indicates a voltage fault will output a high
level.
Current and Voltage monitor
The output terminal of current and voltage monitor sources a 0~10 V
analog signal that represents the input from zero to full range. Users can use
an external voltmeter or oscilloscope to observe the trend of the input current
or voltage.
Short-circuit monitor
The load can deliver a short circuit at the input terminals. The protection
functions are still active even when using the short circuit function. Press
Shift and Short key to switch the short circuit status. The short circuit status
does not influence existing setting values. When exiting short-circuit mode,
the load will return back to the original setting status.
Protection Functions
Overvoltage protection (OVP)
The load will be immediately disable the input, the buzzer will sound, and
the LCD screen will pop-up an overvoltage message if overvoltage protection
is triggered. The VF pin on the rear board will output a TTL high level signal if
overvoltage occurs. This signal can be used to monitor the output status of
