Chapter 2 — Operation
Introduction
The Humilab is very simple to operate. Minimal operator training is
required for successful calibration of humidity recorders, transmit-
ters, or hand-held portables. Typically, only the R.H. setpoint
selector switch is used in a calibration. All other switches are set as
desired and then left in position.
Front panel switch settings are described in this chapter. More
detail is available in Appendix B. For quick reference, the following
settings are typical for most applications:
• Power Switch: ON (mounted on rear of unit)
• Sensor Switch: OPERate
• Display Switch: OPERate
• Loop Switch: Closed Loop (Set to the filled-in circle) for oper-
ation; Open Loop (open circle) for uploading profiles
• Balance Switch: Center position
• Auto/Cal Switch: OPERate
• Setpoint: Set to desired chamber humidity
