(5) Computer-controlled test and data acquisition software

Test Procedures

Connect the test sample to the test air adapter, pressure port, and temperature sensor.

Place the test sample in ambient conditions or inside a climatic chamber if required.

Select overpressure or low-pressure test mode according to the test requirement.

Apply compressed air or vacuum to establish a stable pressure condition inside the sample.

Measure pressure, volume flow, and gas temperature continuously during the test.

Calculate the leak rate automatically based on flow behavior and pressure differences.

Record and evaluate the test results using the computer-controlled system.

Maintenance Information

Regularly inspect laminar flow elements to ensure accurate flow measurement.

Keep compressed air clean and dry to prevent contamination of measurement components.

Verify pressure and temperature sensors periodically for calibration accuracy.

Check seals, hoses, and connectors for wear or leakage before each test series.

Ensure proper functioning of the heat exchanger when operating at extreme temperatures.
