4.2. Connecting Pressure Tubes

The device features two pressure ports at the top for differential pressure measurement. Use the provided transparent tubes to connect to the pressure source:

1. Identify the two 1/8'' (3.18 mm) quick coupling plungers at the top of the device.
2. Gently push one end of a transparent tube onto each plunger until it is securely fitted.
3. Connect the other ends of the tubes to the points where pressure needs to be measured. Ensure proper connection for accurate readings.

• Ensure no pressure is applied to the ports.
• Press the ZERO button. The display should show '0.000' or very close to zero.

5.3. Changing Measurement Units

The device supports multiple pressure units.

• Press the UNIT button to cycle through available measurement units (e.g., kPa, psi, bar, mmHg, etc.).
• The selected unit will be displayed on the screen.

5.4. Data Hold Function

To freeze the current reading on the display:

• Press the HOLD button. The current reading will be held on the display.
• Press the HOLD button again to release the hold and resume live readings.

5.5. Differential Measurement (DIF)

The DIF button is used for differential pressure measurements, comparing two pressure inputs.

• Connect the pressure sources to the two ports.
• Press the DIF button to activate differential measurement mode. The display will show the difference between the two inputs.
• Press DIF again to exit this mode.

5.6. Backlight Control

For improved visibility in low-light conditions:

• Press the Backlight button (light bulb icon) to turn the display backlight on or off.

5.7. Record Function
