Multiple parameters of mine ventilation Detector
>Working Principle
The instrument is composed of a low-power single-chip microprocessor and peripheral interface circuits. The peripheral interface circuit is composed of, frequency/digital conversion circuit, analog/digital conversion circuit, serial communication circuit, clock circuit and. The frequency signal and temperature compensation voltage signal of the pressure sensor are sent to the calculated pressure value after /conversion and /conversion respectively, and then the pressure value is sent to the display for display. Similarly, the wind speed and humidity sensor signals are also sent to the calculation after / and /conversion. Wind speed and humidity values. The output of the temperature sensor is a digital signal, so it does not need to be converted and is directly sent to calculate the temperature value.

>Measurement Operation
Display Settings
Through the display setting menu, you can set the parameters that need to be displayed on the display. You can choose to display the parameter on the screen by selecting the highlighted parameter on the menu, or turn off the display of the parameter by selecting, and select the main parameter to display the parameter in a large font on the screen. Only one parameter can be selected to be displayed as the main parameter. In addition, up to three parameters can be selected and displayed on the screen as secondary parameters.
Pressure Clear
Select the (Pressure Clear) menu to clear the pressure reading. The host will display whether the reset is successful.
Settings
Through the settings menu, you can complete basic settings including parameter units, system time, system date, time format, turning off the backlight, and automatic shutdown. Use the or keys to adjust each option setting and then press the OK key to confirm the setting.
Actual/Standard Settings
In the menu item Select/Options, the user can select the standard temperature, standard pressure and actual temperature source. The ventilation multi-parameter detector measures the actual atmospheric pressure.

>Maintenance
No special maintenance is required to maintain good condition
The calibration menu can be used for calibration during on-site testing, for the purpose of on-site debugging It uses minimal adjustments to meet user calibration standards. On-site adjustment is not a complete calibration. In order to achieve completeness, multi-point calibration and verification are required, and the calibration is sent to the manufacturer or a nationally authorized measurement institution for annual recalibration.

>Common faults and solutions Problems and possible causes of faults and solutions
The screen does not show that the power is not turned on
The battery is low or exhausted Replace the battery or use an AC adapter
Poor contact in the battery compartment circuit. Clean the battery compartment circuit
The wind speed reading is unstable and the flow field is unstable. Reposition the probe to a place where the flow field is stable or use a large time constant
The keyboard is unresponsive. The keyboard is locked and press ▲▼ at the same time to unlock the keyboard
An instrument error message appears. There is no memory space to download the required data and then deletes all data.
A probe error message appears. The probe is faulty. The probe needs to be returned to the factory for repair
