3. Enstriksyon Enstalasyon

Follow these steps to set up your Elitech Smart Digital Manifold Gauge DMG-4B for initial use.

3.1. Initial Calibration and Refrigerant Selection

Before each measurement, it is crucial to calibrate the pressure sensor and select the correct refrigerant type.

Ensure there is no connection between the gauge and any pressure source. The gauge should be at atmospheric pressure.
Long press the 'Zero' button to calibrate the pressure sensor. The calibration range is 1-100psi.
To switch the refrigerant type, long press 'Zero' and the 'Down Arrow' button together. Then, short press 'Up Arrow' or 'Down Arrow' to cycle through available refrigerant types.

Select the refrigerant types you wish to add or remove from your 'Favorite' list by touching the star icon.
Click the update icon in the upper right corner to save your settings and synchronize with the device.

4.2. Pressure Holding Test (Requires In-App Purchase)

This function allows you to test the pressure integrity of your system.

Connect the high-pressure refrigerant hose to the testing system and close the high-pressure valve.
In the app, navigate to 'Settings' and then 'Hold Pressure Setting'.
Set the charging warning value, decay ratio, enable/disable temperature compensation, and set the pressure-holding time.
On the device, press and hold the 'MODE' and 'Down Arrow' keys simultaneously to enter the pressure-holding test.
Inject gas into the system until the pressure reaches the charging warning value. The device will flash and emit a sound.
Click the 'Down Arrow' button on the device to begin the leak test. The timer will start counting down.
If the pressure remains within the acceptable leak value (calculated based on decay ratio), the test is successful. Otherwise, it indicates a leak.

4.3. Vacuum Measurement (Requires In-App Purchase)

Measure the vacuum level of your system.

Connect the system to the high-pressure side of the manifold and open the high-pressure valve.
Simultaneously press the 'MODE' and 'Down Arrow' buttons twice on the device to enter the vacuum mode.
Connect one end of the refrigerant pipe to the vacuum pump.
Start the vacuum pump and extract pressure from the system. The device will display the vacuum degree and elapsed time.

4.4. Offline Data Logging (Requires In-App Purchase)

Record measurement data directly on the device for later analysis.

In the app, navigate to 'Settings' and then 'Record Function'.
Select the desired recording interval (e.g., 1s, 10s, 1min).
Click 'Start Offline Recording'. The recording icon on the device will light up and flash.
To stop recording, click 'Stop Offline Recording'. The recording icon will turn off.
Pou view or export historical data, click 'Read Device History Data' in the app. Data can be exported in PDF or Excel format.
To clear historical data from the device, click 'Clear Historical Data' in the app.
