beep is on), the ON/OFF button indicator flashes.

OVP
When the voltage output range is from 0V to 150V, and the output voltage exceeds the set voltage 5V, or when the
voltage output range is from 0V to 300V, and the output voltage exceeds the set voltage 10V, the display will display
“OVP”, alarm beep (when the beep is on), the ON/OFF button indicator flashes.

LVP
When the voltage output range is from 0V to 150V, and the output voltage less than the set voltage 5V, or when the
voltage output range is from 0V to 300V, and the output voltage less than the set voltage 10V, the display will display
“LVP”, alarm beep (when the beep is on), the ON/OFF button indicator flashes.

OCP
When the output current exceeds 110% of the rated full load current for 1 s continuously or the output is shorted, the
display will show “OCP”, alarm beep (when the beep is on), the ON/OFF button indicator flashes.

OPP
When the output power exceeds 105%~110% of the rated full load power for 5s continuously, or less than 1s output
power exceeds 110% of the rated full load power, the display will show "OPP",
alarm beep (when the beep is on), the
ON/OFF button indicator flashes.

OTP
When the temperature of the heat sink of the instrument exceeds 60 °C, the fan accelerates; When the temperature of
the heat-
sink of the machine exceeds 130 °C, the display will show “OTP”, alarm beep (when the beep is on), the
ON/OFF key indicator flashes.

Note: When an abnormal action occurs, the display will show the status of the message when the error occurred, at this
point, the output will be turned off,
alarm beep (when the beep is on), the ON/OFF button indicator flashes, press
the ON/OFF key to release the Alarm.

Remote Signal Output Function
There is a remote signal output terminal (SIGNALOUT terminal) on the rear panel of the instrument, provide
signals such as “PASS”, “FAIL” and “PROCESSING” of the instrument for remote monitoring. This function can
only be used if the test result is set to “P/F”. The wiring of each output signal is shown in Figure 5-13.

1) PASS Signal Connected between PIN1 and PIN2
Note: After the DUT passes, the relay will connect PIN1 and PIN2. After pressing the Escape key, the relay will return
