MOUT
Control Loop Manual Heater Power (MHP) Output Command
Input:
MOUT <loop>, <value>[term]
Format: n,

nnnnnn[term]
<loop> Specifies loop to configure: 1 or 2.
<value> Specifies value for manual output.
Example: MOUT 1,22.45[term] – Control Loop 1 manual heater output is 22.45%.
MOUT?
Control Loop Manual Heater Power (MHP) Output Query
Input:
MOUT? <loop>[term]
Format: n
<loop> Specifies which loop to query: 1 or 2.
Returned: <value>
Format:

nnnnnn[term] (Refer to command for description)
PID
Control Loop PID Values Command
Input:
PID <loop>, <P value>, <I value>, <D value>[term]
Format: n,±nnnnnn,±nnnnnn,±nnnnnn
<loop> Specifies loop to configure: 1 or 2.
<P value> The value for control loop Proportional (gain): 0.1 to 1000.
<I value> The value for control loop Integral (reset): 0.1 to 1000.
<D value> The value for control loop Derivative (rate): 0 to 200.
Remarks: Setting resolution is less than 6 digits indicated.
Example: PID 1,10,50[term] – Control Loop 1 P is 10 and I is 50.
PID?
Control Loop PID Values Query
Input:
PID? <loop>[term]
Format: n
<loop> Specifies which loop to query: 1 or 2.
Returned: <P value>, <I value>, <D value>[term]
Format: ±nnnnnn,±nnnnnn,±nnnnnn (Refer to command for description)
RAMP
Control Setpoint Ramp Parameter Command
Input:
RAMP <loop>, <off/on>, <rate value>[term]
Format: n,n,±nnnnn
<loop>
Specifies which loop to configure: 1 or 2.
<off/on> Specifies whether ramping is 0 = Off or 1 = On.
<rate value> Specifies setpoint ramp rate in kelvin per minute from 0.0 to 100. The rate is always
positive, but will respond to ramps up or down. A ramp setting of 0.0 will cause the
instrument to respond as if the ramp is off, i.e. setpoint changes will be immediate.
Example: RAMP 1,1,10.5[term] – When Control Loop 1 setpoint is changed, ramp the current setpoint to the
target setpoint at 10.5 K/minute.
