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
Open the valve on the regulator
Within 30 seconds, if the R ECON /B S ERIES detects the calibration gas, it will
start up the calibration date analysis procedure by itself. Continue gas flow.
The Display
will indicate gas level
as gas is detected
In 2 to 3 minutes the R ECON /B S ERIES will automatically adjust the conversion
arithmetics to complete the gas response process. Then the R ECON /B S ERIES
saves the best arithmetics to complete calibration.
W ARNING : The R ECON /B S ERIES 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 R ECON /B S ERIES 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.
