Only the password is correct can the detector enters into the zero calibration mode.
Note:
As all the parameters of this mode may endanger the safety of the operator, so please make
the operation carefully Within 10s after indicating inputting the password, if there is no
operation or the password is wrong, the detector will be deactivated. So please input the
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:
