5. Operating Instructions

5.1. Power On/Off

Press the POWER button (red button with power symbol) to turn the device on or off.

5.2. Zero Calibration

Before taking measurements, it is recommended to perform a zero calibration. Ensure both input ports are open to atmospheric pressure (or connected to the same pressure source for differential zeroing). Press the ZERO button to calibrate the device to zero. This compensates for any sensor drift and ensures accuracy.

5.3. Unit Selection

Press the UNIT button to cycle through the 13 available pressure units. The selected unit will be displayed on the LCD screen.

5.4. Measurement Modes (MAX/MIN/AVG)

Press the MODE button to switch between normal measurement, Maximum (MAX), Minimum (MIN), and Average (AVG) display modes. This allows you to capture peak, lowest, or average pressure values over a period.

5.5. Data Hold

Press the HOLD button to freeze the current reading on the display. Press it again to release the hold function and resume live measurements.

5.6. Data Recording and PC Software

The manometer can record data internally. For advanced data logging, trend analysis, and customizable settings, connect the device to a PC using the provided USB cable and the dedicated software. The software allows for unlimited data storage, real-time monitoring, and data export.

5.7. Time and Date Setting

Use the TIME/DATE button to access and adjust the device's internal clock and calendar. Refer to the full instruction manual for detailed steps on setting the time and date.

6. Maintenance

6.1. Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the input ports are free from dust and debris.

6.2. Storage

When not in use, store the manometer in its protective carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. Remove hoses if storing for extended periods.

If you encounter issues with your DANOPLUS DP-420, refer to the following common problems and solutions:

7.1. Device does not power on

Check the battery level. Recharge the device if the battery is low or depleted.
Ensure the power button is pressed firmly and held for a moment.

7.2. Inaccurate readings

Perform a zero calibration before measurement.
Ensure hoses are securely connected and not kinked or blocked.
Verify that the correct pressure unit is selected for your application.
Ensure the measurement environment is stable and free from sudden temperature changes.

7.3. PC software not connecting

Ensure the USB cable is properly connected to both the manometer and the PC.
Check if the necessary drivers for the device are installed on your PC.
Restart the PC software and the manometer, then try connecting again.
Try a different USB port on your computer.
