Meter

A toggle switch that turns the input of the electronic load on or off.

Activates front panel control when the unit is in remote mode (unless a Lockout command is in effect).

Increases the input current (CC), voltage (CV), or resistance (CR) in Meter mode.

Decreases the input current (CC), voltage (CV), or resistance (CR) in Meter mode.

Selects another channel.

Causes an initiate and trigger to occur. Used with transient subsystem or list.

Displays any protection functions that are tripped.

Resets the protection circuit and allows the unit to return to its last programmed state.

Identifies the module installed in the selected channel location. (not available)

Returns the front panel to metering mode from any other mode.
