right password in time.
Zero calibration
In this mode, the detector will display a figure it detected as shown in the following chart:
At this time, if is pressed or no operation within 1 minute, the detector will accept the
present concentration as the zero point, and then enters into the mode of calibration
point set up. And press , it jumps over the calibration step to enter into the mode of
alarming level set up, with reference to the 5 and 6 items.
Warning：This operation should be carried out in the clean air. Otherwise the accuracy of the
detector will be affected differently according to the different gas concentration in the air.
When entering into the next mode, if it displays E, which means the air is not clean, or
the sensor is destroyed. So please choose another adjustment place or replace the
sensor.
Calibration point adjustment
In this mode, the screen displays a set of flickering figures. Press or to modify
this figure. This figure is the standard sample gas level with which the operator needs to
calibrate the detector, as shown in the following chart:
At this time, if is pressed or no operation within 1 minute, the
detecor will accept the present concentration as the calibration gas
concentration, and then enters into the mode of calibration point set
Calibration point adjustment
In this mode, the detector displays a concentration value detected as shown in the
following chart:

At this time, please cover the gas response hole with the calibration cap, open the gas
valve to adjust the flux as 120mL/min. Within 30 seconds, if the detector detects the
calibration gas, the detector will start up the calibration date analysis procedure by itself.
And the detector will automatically adjust the conversion arithmetic till all the standard
gas complete the response. Then the detector saves the
best arithmetic and complete the calibration. After that it enters into
the L-alarm set up.
Note: In this mode, please avoid touching any buttons, otherwise the accuracy will be effected
badly. If the detector indication figure can’t reach half the calibration figure within 30s, or
the gas concentration is beyond the maximum drift range of the sensor, the E ico will
light, which means the gas is not proper for calibration or the sensor is destroyed. Please
replace the gas or the sensor. The calibration of O2 sensor will jump over process two
previous steps
