Calibrating The Unit; Connecting The Hardware - Honeywell 301EM Mode D'emploi

Programming and Calibration

Calibrating the Unit

Calibrating the Unit
Honeywell provides its customers with specialized gas detection
equipment. Beyond the warranty period, the systems must be maintained
and calibrated on a regular basis (normally twice a year).
If unit span or zero cannot be adjusted, the sensor may be approaching
its end-of-life and must be replaced. Keep an operation log of all
maintenance, calibrations and alarm events.
The unit requires warm-up time before being put into service and
calibrated. The warm-up time required depends on the type of sensor,
however a standard minimum of fifteen (15) minutes is recommended.

Connecting the Hardware

1. Plug the calibration adaptor onto the gas sensor inlet.
2. Screw the regulator to the appropriate calibration gas cylinder (for
either span or zero adjustment) and set the flow rate (see Table I on
page 47).
3. Connect the tubing to the regulator outlet and to the calibration
adaptor or to calibration port.
