3.6 Output Operation

If you control the power supply by front panel, you can press

On/Off

and switch

the state of output. If power supply is under remote sense, you can send SCPI

order (OUTPut ON|OFF) to change the state of output.

3.7 Remote Sense

The wire connected the power supply and electronic load will produce voltage

difference when the current of the power supply is so big. In order to make the

measurement accuracy much accurate, there are 4 pin trigger and remote sensing

connectors on the rear panel and you can use it to measure the output voltage of

the tested instrument. You must set remote sense mode before you start remote

test function.

INH: this port hat multiple function

When “Port Mode” in the menu is set with “Trigger”, INH is trigger port.

When “Port Mode” in the menu is set with “RI/DIF”, INH can set the output status

on/off. Here INH port has 3 working mode to choose.

LATCHING: When the level of INH port changes from high to low, the output of

power supply is off.

LIVE: The output state of power supply changes along with the level of INH port. If

the level of INH is 1, the output is on; and the level of INH is 0, the output of power

supply is off.

OFF: The level state of INH do not affect the output state of power supply.

When “Port Mode” in the menu is set with “DIGITAL I/O”, INH port becomes the

digital input port to read input status by communication order.

FLT: This port hat multiple function

When “Port Mode” in the menu is set with “Trigger”, FLT is an invalid port.

When “Port Mode” in the menu is set with “RI/DIF”, FLT port can find fault of power

supply.

FLT source contains QUES, OPER, ESB, RQS, OFF.

QUES: The output level of FLT changes along with the state of QUES bit. When
