The LMT lamp lights up to show that the unit is currently in limit display state.
When the lamp is off, the unit is in ReadBack Display (actual output voltage/current) mode.
The procedure below is for setting the limit display.

*Limit Display in Output OFF mode

▌Turn on the power switch.

   After turning on power, check if the unit is in "**OUTPUT OFF**" mode.

▌Press the Limit Display key to view the voltage and current limitations.

▌The LMT lamp lights up, and the LCD shows the currently set voltage and 

current values. 

   Displayed LCD Message

00.00V    88.00A 

▌By using the cursor keys and encoders in this state, the voltage and current

   settings can be changed.

▌Press the IO/Local key once more

   to disable the voltage and current settings mode.

   Displayed LCD Message

**output off** 

*Limit Display in Output ON mode

▌Turn on the power switch.

   After turning on power, check if the unit is in "**OUTPUT OFF**" mode.

▌Press the Output ON/OFF key for voltage and current output.

   Displayed LCD Message

00.00V    00.00A 

▌Press the Limit Display key to view the voltage and current limitations.

▌The LMT lamp lights up, and the LCD shows the currently set voltage and 

current values.

   Displayed LCD Message
