Pulse unit. However, if compressors not supplied by Build Test Solutions are used to charge the instrument it is imperative that the compressor is approved and configured for charging to no greater than 10Bar and that the correct couplings necessary for connection to the Pulse unit are used (Prevost S1 series euro connectors). -
Page 10: Service & Maintenance Requirements
5 Service & Maintenance Requirements The Pulse unit requires regular maintenance and calibration to ensure correct measurement. The following service schedule should be maintained for all testing. A fully serviced Pulse unit is mandatory for regulatory testing and where testing results are intended to be used to demonstrate improvements which may be later monetised or promoted. -

Page 12: Scope Of Use
To ensure successful testing, it is recommended that users oversize the Pulse unit to be used. Build Test Solutions maintain a publically accessible Pulse system sizing guide available online here: https://www.pulseairtest.com/sizing-guide.html Above: Example screenshot of the online Pulse system sizing tool.

Page 14: Initial Setup
When transporting in a vehicle, it is advised that precautions are made to ensure the unit cannot move around within the vehicle, by strapping or otherwise. When manually handling the instrument, please ensure you have received the correct manual handling training and, if necessary procured the necessary lift aids as per your personal requirements or risk assessment. -

Compressor charge hose connection to air receiver Compressor charge hose with push-fit fittings NOTE: FOR THIRD PARTY SUPPLIED COMPRESSORS, ENSURE YOUR COMPRESSOR IS SET TO CHARGE TO 9- 10BAR TO ENSURE THE TANK’S SAFETY VALVE IS NOT TRIGGERED. When the air receiver has reached fully-charged, the compressor will switch off automatically. This should take approximately 8 minutes for a single standard 40L air receiver to fully charge from empty to its max 10 bar capacity. -
Page 16: Step Tests
Use the control system to set up the test and input testing parameters. Section 8 provides comprehensive guidance on using the control system. When “start test” shows on the screen, the test is ready to launch. PLEASE NOTE: Testing without inputting building envelope area and volume will mean test results will not be provided on-screen and will require calculation later. - Page 17 AP – Air Permeability (m Achieved Pressure Range (Pa) A test ID will also be displayed, this should be noted for records. At the end of the test the results are automatically captured in the unit’s memory. These may be exported as .csv or .Pat file (depending on the version of Pulse unit and software you are running) by plugging in a USB and following export guidelines in section 8.3.

Page 18: After Testing
Invalid The air flow exponent, n, is used to describe the airflow regime through the gaps and holes in Exponent the building fabric. Values must range between 0.5 and 1.0. An n value approaching 0.5 signifies turbulent flow, representing high flow through large apertures. An n value Threshold approaching 1.0 will indicate a more laminar flow, characteristic of more air tight structures or those with much smaller gaps and holes. -
