LOOP {1 | 2 | 3 | 4}:HTRRead?
Queries the actual output power of either control loop. The output current of
the heaters is continuously monitored by an independent read-back circuit.
The read-back power reported by this command is a percent of full scale. The
absolute value of full scale is determined by the selected heater range.
Note that the read-back value is a percent of full-scale power. To compute the
output current, first compute the square-root of the read-back value.
LOOP {1}:LOAD {50 | 25}
Sets or queries the load resistance setting of the primary heater (Loop 1).
Selections are:
50 for a 50 load and a 50W maximum output power.
25 for a 25 load and a 25W maximum output power.
Note: Loop 2 always requires a 50 load so this command is ignored.
LOOP {1 | 2 | 3 | 4}:MAXPwr <maxpwr>
Sets or queries the maximum output power setting of the selected control
loop. <MaxPwr> is the desired maximum output power limit expressed as a
percentage of full scale.
LOOP {1 | 2 | 3 | 4}:MAXSet <maxset>
Sets or queries the maximum allowed set point for the selected control loop.
<MaxSet> is the desired maximum set point. Setpoint values are in units of
the controlling input channel.
LOOP {1 | 2 | 3 | 4}:VSENse?
Queries the control loop output voltage. If the instrument is not controlling
temperature, return is 0.00V.
LOOP {1 | 2 | 3 | 4}:ISENse?
Queries the control loop output current. If the instrument is not controlling
temperature, return is 0.00A.
LOOP {1 | 2 | 3 | 4}:LSENse?
Queries the control sensed load resistance. If the instrument is not controlling
temperature, return is -1.00.
LOOP {1 | 2 | 3 | 4}:HTRHst?
Queries the temperature of the control loop's heat sink. Valid for loops #1 and
#2 only. Returns temperature in ºC.
