Syntax
: Short Form: FUNC:MODE
Long Form: [SOURce]:FUNCtion:MODE
Function
: FUNC:MODE VOLT Commands power supply to Voltage mode
FUNC:MODE CURR Commands power supply to Current mode
Description
: Commanded mode establishes parameters (voltage or current) monitored for error conditions. Actual
mode depends upon load conditions. When commanded to Voltage mode, if load conditions cause the
power supply to try to exceed the current limit, the unit will automatically switch to Current mode and
flag an error condition. When commanded to Current mode, if load conditions cause the power supply
to try to exceed the voltage limit, the unit will automatically switch to Voltage mode and flag an erro
r
condition.
Example
: FUNC:MODE VOLT Power supply commanded to Voltage mode.
VOLT 21; CURR 1.1 Power supply commanded to output 21V, current limit set to 1.1A.
FUNC:MODE CURR Power supply commanded to Current mode.
CURR 1.1; VOLT 21 Power supply commanded to output 1.1A, voltage limit set to 21V.

Function
: Returns the value of the Operation Condition Register to controller (1 = set = function enabled, 0 =
reset = function disabled).
Description:
The Operation Condition Register contains unlatched real-time information about the operating condi-
tions of the power supply.
Example:
STAT:OPER:COND? Power supply returns <value> 1536 (1024 + 512) to indicate that power
supply is operating in Current mode with relay closed.
