CALIBRATION
Tools Required
Calibration requires the following tools, shown in Figure 48:
— Thermostat Tool CCT735A (MQT735A)
— Gage 305965 (0 to 30 psi [0 to 210 kPa])
— Gage Port Needle CCT729 (MQP729)
— Digital Relative Humidity Indicator Pen CCT915 for
humidistats and humidity sensors
— Test Thermometer CCT902 (MQT902) for thermostats
and temperature sensors

Humidistat/Humidity Sensor
General
After installing the humidistat, set the humidistat to the
desired setpoint and let the system operate long enough to
stabilize. The length of time required for stabilization depends
on system response time and could be only a few minutes or
as long as several hours. Verify that the system has stabilized
before checking calibration.
NOTE: Humidistats and humidity sensors are factory
calibrated and should require only a bleed-off check
to ensure correct operation. The throttling range is
factory set and should not require adjustment under
normal operating conditions.
