MicroDock II Automatic Test and Calibration Station 52
Calibrate the sensor if the ambient gas display varies during start-up.
•
Calibrate a new sensor before use. Allow the sensor to stabilize before
•
starting calibration:
Used sensor: 60 seconds
New sensor: 5 minutes.
Calibrate the sensors at least once every 180 days, depending upon use and
•
sensor exposure to poisons and contaminants. For HCN sensors, calibrate
at least once every 90 days.
Calibrate the sensor before changing the alarm setpoints.
•
When calibrating multiple times, wait 10 minutes between calibrations to
•
allow the sensor to stabilize.
If a certified calibration is required, contact your local Distributor or
•
Honeywell Analytics.
Calibration Procedure
Calibration is performed to adjust the sensitivity level of a sensor to ensure an
accurate response to gas.
CAUTION
Ensure the detector is not in a low battery state prior to performing a
calibration.
The station automatically accepts an unusually large span adjustment notification
for the X5. Refer to the X5 Operating Manual.
To perform a calibration, complete the following:
Ensure the MMC card is inserted if datalogging is required. 1.
If the MMC card is not inserted, displays on the LCD when the station
attempts to log the results of the calibration. If required, refer to Inserting/
Replacing a MMC Card.
Activate the detector and wait until it is in normal operating mode. Insert it 2.
into the docking module.
Activate the station and access the normal operating screen. 3.
Press 4. CALIBRATION on the corresponding docking module.
If calibration is initiated while in the user menu: Calibrations that are
queued while in the user options menu are initiated only when the user
options menu is exited.
If more than one docking module is queued: If more than one docking
module is queued for calibration, the first module queued begins the
calibration.
The RUN LED flashes yellow on the remaining docking modules that are
queued for calibration. When the first module is complete, the next module
in the queue begins calibration.
The station begins the calibration and displays the
bay number,
