Lake Shore Model 332 Temperature Controller User's Manual
Allows selection of control input, setpoint units, closed or open-loop control mode,
power up enable, display of heater output units, setpoint ramp enable, and ramp
rate for the currently selected loop. Refer to Paragraph 4.7 for control setup and
Paragraph 4.12 for ramp feature.
Allows entry of control setpoint for the currently selected loop. Refer to Paragraph
4.11. A discussion of the ramp feature is provided in Paragraph 4.12.
Allows entry of up to 10 temperature control zones of customer-entered PID
settings and Heater Ranges for the currently selected loop. Refer to Paragraph
4.10.
Allows manual adjustment of control parameters Proportional, Integral, and
Derivative, or Manual Heater Power (MHP) output for the currently selected loop.
Refer to Paragraph 4.8.
Allows selection of sensor input type and curve. Refer to Paragraph 4.4 for sensor
input setup and Paragraph 4.5 for curve selection.
Allows entry of up to twenty 200-point CalCurves or user curves and SoftCal.
