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
