5.2. Connecting Pressure Tubes
Connect the provided soft tubes to the manometer's input ports and to the pressure source you wish to measure.
- Attach one end of a soft tube to the '+' port on the manometer.
- Attach the other end of the tube to the high-pressure side of your system.
- For differential pressure, attach a second soft tube to the '-' port and to the low-pressure side of your system.
- Use the RMA316 tube adapters if required for specific connections.

6.3. Data Hold
Press the HOLD button to freeze the current reading on the display. The 'HOLD' indicator will appear. Press the button again to release the hold function and resume live readings.
6.4. Recording (MIN/MAX/AVG)
Press the REC button to enter recording mode. The display will show the maximum (MAX), minimum (MIN), and average (AVG) pressure values recorded since entering this mode. Short press the REC button to cycle through MAX, MIN, and AVG values. Long press the REC button for 5 seconds to exit recording mode.
