3.8 Calibration
In order to assure the testing accuracy,
ENMET
Corporation suggests that the
RECON-IS
be calibrated at a minimum of every
180 days. The calibration procedures are as follows:
1. In clean air, press the button till the detector is turned
off, keep pressing the button, the detector will turn on
again, the screen displays time count-down of 3 second.
2. When the screen displays “CAL”, release the button
and the detector enters calibration status.
3. The detector will first calibrate the zero point. Please
connect the detector to the gas bottle and input high-pure
N2 into the detector at the speed of 120ml/min. Or put the
detector in the clean air and it will calibrate zero.
Example:
4. When the screen displays flashing calibration points,
connect the cylinder regulator, calibration gas and sensor
cover to the instrument. In 30 seconds’ display will
indicate numbers Example 1476 and continue to change
until the sensor response stabilizes If no gas input within
30s, the system treats the calibration as failed.
Example CO

Calibration Gas
5. If the standard gas is input normally, the detector will
adjust once every 3 seconds till the system is steady and
the calibration is finished. If calibration succeeded, the
screen displays “S” and the detector turns off.
6. If calibration failed, the screen displays “F C” for 30
second. During this period, the user can press the button
to repeat the calibration.
7. During the 30 seconds of “F C” flashing, if no
operation, the calibration failed. The screen will display
“F” and the detector turns off automatically.
