5.1.3 Calibration Point Adjustment
In this mode, display is the last concentration of gas used to calibrate the
instrument. Press UP or Down button to modify the display.
N OTE : Not used with Recon Oxygen units
N OTE : 20.9% Oxygen is the only calibration level to be used with Recon Oxygen units
Press the S ET button to accept the level or within 1 minute, the RECON
will accept the present concentration as the calibration gas concentration.
The display will change to 0..
Open the valve on the regulator
Within 30 seconds, if the RECON detects the calibration gas, it will start up the
calibration date analysis procedure by itself. Continue gas flow.
In 2 to 3 minutes the RECON will automatically adjust the conversion
arithmetics to complete the gas response process. Then the RECON saves the
best arithmetics to complete calibration.
W ARNING : The RECON must self calibrate, please avoid touching any
buttons, otherwise the accuracy will be effected badly.
After that it enters into the L-alarm set up. Press P OWER button twice to
advance and exit.
If the RECON can not reach half the calibration figure within 30 seconds, or the gas concentration is outside the maximum
drift range of the sensor, the E icon will light and 0000 will be displayed. This means the gas is not proper for calibration or the
sensor is depleted.
Verify calibration gas is correct. If correct retry calibration sequence. If failure occurs sensor may need to be replaced.
Remove calibration cover from instrument.
To exit calibration menu.
Press S ET button 3 times and then the P OWER button 4 times.
