Output Voltage Polarity Command
POLARITY <output>,<polarity>[term]
n,n
<output>
<polarity>
The polarity command only applies to Output 2, and only when output type is voltage.
Output Voltage Polarity Query
POLARITY?[term]
<polarity>[term]
n (refer to command for description)
Control Setpoint Ramp Parameter Command
RAMP <output>,<off/on>,<rate value>[term]
n,n,nnnn
<output>
<off/on>
<rate value>
RAMP 1,1,10.5[term] when Output 1 setpoint is changed, ramp the current set-
point to the target setpoint at 10.5 K/minute.
Control loop settings are assigned to outputs, which results in the settings being
applied to the control loop formed by the output and its control input.

Output for which to configure the polarity setting: 2
Specifies output voltage is 0=unipolar (positive output
only) or 1=bipolar (positive or negative output)
Specifies which output's control loop to configure: 1 or 2.
Specifies whether ramping is 0 = Off or 1 = On.
Specifies setpoint ramp rate in kelvin per minute from
0.1 to 100. The rate is always positive, but will respond to
ramps up or down. A rate of 0 is interpreted as infinite, and
will therefore respond as if setpoint ramping were off.
Specifies which output's control loop to query: 1 or 2.
Specifies which output's control loop to query: 1 or 2.
0 = Not ramping, 1 = Setpoint is ramping.
