3.2 માપન મોડ્સ

The PCE-423N supports various measurement modes. Use the mode selection buttons (refer to the device's button layout) to switch between:

• હવાની ગતિ: Measures air velocity in m/s or ft/min.
• Volume Flow: Calculates air volume flow in m³/h or CFM. Ensure correct duct area input if required by the device.
• તાપમાન: Measures air temperature in °C or °F.

For accurate air speed and volume flow measurements, ensure the sensor tip is positioned correctly within the airflow. The sensor tip is located at the end of the telescopic probe.

3.3 Data Memory and Transfer

The device can store up to 10,000 measuring points. Refer to the on-screen menu for options to save data manually or configure automatic logging intervals. Saved data can be exported in CSV format.

To transfer data to a computer:

1. Connect the PCE-423N to your computer using the Micro-USB cable.
2. The device should appear as a removable storage device.
3. CSV શોધો files containing your measurement data and copy them to your computer.

3.4 Using the Tripod Bracket

The PCE-423N is equipped with a 3/8" tripod bracket on its back, allowing for stable, hands-free measurements, especially useful for long-term monitoring or in specific setups.
