2. The language can be Chinese or English; date and time can be set as year, month, day, hour, minute; if auto storage is on, the measured data will be automatically saved according to the set recording interval. If not, it will not be stored automatically; if the auto-off is on, if there is no button operation within the set shut­down time, it will automatically shut down. If auto-off is not on, it will not automatically shut down; in the backlight setting, there are three levels of backlight brightness; restoring the factory setting can restore all parameters except for date and time (including calibration parameters)in the instrument to factory state.

Calibration Interface {ONLY FOR PROFESSIONAL}

Sensor Calibration Selection Interface (Such as Figure 12)

1. In the interface of Figure 12, the left side is the calibration point option.the right side is the calibration parameter corresponding to each calibration point, and the real-time value,minimum value, maximum value,average value and signal value graph of sensor signals are displayed in the lower right area ; the concentration setting refers to setting the concentration value to be calibrated; calibration AD value refers to the signal value output by the sensor corresponding to the set concentration value; offset adjustment refers to the reading plus or minus the set deviation on the basis of the calibration point; timing calibration means that after the timing calibration is on, the countdown of the set timing starts. When the countdown reaches 0, the measured signal value is automatically stored in the calibration AD value. Manual calibration means that when the manual calibration is on, the realtime signal value is stored in the calibration AD value by pressing” “button; the value between manual calibration icon and ENTER icon is the real-time measured concentration value.

Three Sensor Calibration Methods

1. there are three kinds of calibration methods:
2. Input the calibration AD value directly

  *         * Set concentration value.
    * Open to calibration gas which has set concentration value;
    * Wait for the signal curve at the lower right of the screen to be stable;
    * After the signal is stable, input the real-time signal value to the calibration AD value.

2. Manual Calibration:
3. Set concentration value;
4.  Open to the calibration gas which has set the concentration value;
5. Wait for the signal curve at the lower right of the screen to be stable;
6. After the signal is stable, select manual calibration. Press the button to confirm that the icon will be selected. Press the button again and the real-time signal value will be added to the calibration AD value.
7. Timing calibration:
8. Set the concentration value;
9. Open to the calibration gas with the set concentration value;
10. Select timing calibration, press button, input the timing, then the countdown starts, when the countdown reaches 0, the real-time signal value will be added to the calibration AD value.
11. If the calibration is wrong, you can recalibrate or restore to factory settings in system settings.
12. When calibrating the zero point of carbon monoxide, hydrogen sulfide,and combustible gas, you can Increase the calibration AD value by 5-9 to prevent the readings from appearing unrecoverable.
