4.
At this time, pass in the calibration gas at 300±20ml/min. When
the value of the instrument is stable, press the "OK" key. The instrument
will be automatically calibrated and display "PASS" for a short time. At
this time, the measured concentration value is consistent with the value
set in "F-07" (concentration value of calibration gas).
IR AL AH
Note:
Pass the calibration gas into the detector. After the output is
stable, adjust and correct the display value of the detector to be the
same as the calibration gas value, and then cut off the gas. Observe
whether it can return to the zero point (in a pure air environment) or
the starting point, and then repeat it again, and the calibration can be
IR ALAH
completed with a small difference between the two values (within the
basic error range). If there is a big difference, repeat the above method to calibrate until the calibration
specification is met (the detector is usually adjusted to "20.93% VOL" for oxygen in the air environment, and
the detector is usually adjusted to "78.10% VOL" for nitrogen in the air environment).

6 Remote controller operation
1: Press the MENU key once to enter the F-01 address code setting menu, press the "OK" key to enter
the modification, press the "+" and "-" keys to modify the instrument address code, and press the "OK" key to
save after the modification is completed. Press the "BACK" key to cancel.
2: Press the "+" key to enter F-02 to enter the low alarm point setting menu, and press the "OK" key to
enter the modification. Press the "+" or "-" key to modify the low alarm value of the instrument. After the
modification is completed, press the "OK" key to save, and press the "BACK" key to cancel.
3: Continue to press the "+" key to enter F-03 to enter the high alarm point setting menu, and press the
"OK" key to enter the modification. Press the "+" and "-" keys to modify the high alarm value of the
instrument. After the modification is completed, press the "OK" key to save, and press the "BACK" key to
cancel.
4: In the parameter setting state, if the remote controller is not operated for 10 seconds, the
instrument will automatically return to the gas detection state, and the parameters being modified
(without pressing the "OK" key to confirm the operation) will not be saved in the EEPROM. The
parameters used are still the previous values when restarted again.
