V1.0 4 Portable gas detectors you can count on. 14 of 20
Calibration
The detector can be configured to keep track of regular calibration intervals in a Calibration
Log. The interval can be set using the GCT IR-Link software. When a calibration comes due,
or if the last calibration has failed, then the detector’s display will continually flash “ CAL
DUE ” until the detector has been successfully calibrated. Performing a calibration that will
be recorded in the Calibration Log can be done either automatically: insert the detector into
the MGC-S Dock or MGC-S Wall Mount Dock, or manually: apply gas according to the
Manual Calibration Instructions described below.
Manual Calibration Instructions
To enter the Manual Calibration mode, continuously
hold down the power/menu button
during countdown
.
Release the button
when
the “ ZERO
OK
” message
appears. The detector will first automatically zero the
sensors at the current baseline reading, then the “ APPLY GAS ” prompt
will appear. Display will show
:
Once the screen displays “ APPLY GAS ”, snap the MGC-S Calibration Cap (provided with the
detector) into place over the sensor ports. Apply gas to the detector at a flow rate of 0.5 LPM
and do not disturb while calibration is being performed. Sensor readings will be displayed as
the gas is detected and as the detector adjusts the calibration parameters. Once calibration
is complete, the detector will display the next calibration date before returning to normal
(alarming) operation. If a sensor fails to calibrate, the detector will display
“ E
RROR
” - an
error message for the failed sensor. Check your gas connections and concentration before
attempting a second calibration. If a sensor fails to calibrate after a second attempt, contact
GCT for assistance.
Auto Zeroing
To Auto Zero the detector, enter Manual Calibration mode as described above. Once the
screen displays "APPLY GAS" , briefly press the power/menu button. The screen will then
display "CAL ABORT" followed by the number of days remaining before the next set
calibration date. The d etec tor has been successfully auto zeroed and returns to normal
operation.
DO NOT auto zero the detector in a combustible atmosphere.
DO NOT auto zero in temperatures above or below the specified range of 0°C to 40°C.
DO NOT substitute any other battery type than specified and supplied by GCT.
Storage
Store the detector in a safe, dry place between 32°F and 77°F (0°C - 25°C).
Review the warranty period and the “ Activate before… ” date that is printed on the product box label.
R etest
To attempt recovery from sensor " Err ", continuously hold down the power/menu button
during count downs . Release the button when the “ RETEST OK ” message appears. The
detector will retest sensors and auto zero the detector. Auto Zeroing precautions apply.
Battery
This detector is designed so that the battery won't need charging or replacing during the life
of the detector.
