5. Operation
5.1 Power On/Off
Press the POWER button to turn the device on. Press and hold the POWER button to turn it off. The device features an auto power-off function to conserve battery life after a period of inactivity.
5.2 Zero Offset
Before taking measurements, ensure the device is at ambient pressure and press the ZERO button to calibrate the reading to zero. This ensures accurate differential pressure measurements.
5.3 Unit Selection
Press the UNIT button to cycle through the 10 available units of measure (e.g., PSI, kPa, mbar, In H²O). The selected unit will be displayed on the LCD.
5.4 Hold Function
Press the HOLD button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.
5.5 Min/Max Function
The device can display the minimum and maximum pressure values recorded during a measurement session. Refer to the full instruction manual for detailed steps on accessing and resetting Min/Max readings.
5.6 Backlight
The LCD display features a backlight for improved visibility in low-light conditions. Activate the backlight by pressing the light bulb icon button.
6. Data Logging
6.1 Recording Data
To begin recording pressure data, ensure an SD card is inserted. Press the REC button. The device will log measurements along with the date and time at predefined intervals. Press REC again to stop recording.
6.2 Data Transfer to PC
The recorded data is stored on the SD card in a format compatible with Microsoft Excel. To transfer data:
- Remove the SD card from the manometer.
- Insert the SD card into a computer's memory card slot or an external SD card reader.
- Open the data files directly in Microsoft Excel for analysis. No special software or drivers are required.
Additional SD cards can be used for unlimited data storage. Ensure the date and time are set correctly on the device for accurate data logging timestamps.
