No. Your calibrated gauge or manometer measures the pressure. GasTest Log times the required hold, records the start and end gauge photos and your readings, and turns them into a certificate. You read the gauge and attest PASS or FAIL.
The presets show the IFGC 2021 / IRC / NFPA 54 base-code default (e.g. residential 3 psi for 10 minutes). Local amendments vary — some jurisdictions require higher pressures or longer holds — so always confirm the required values with your Authority Having Jurisdiction (AHJ). You can override the pressure and duration on any preset.
Many AHJs accept a signed, documented test report in lieu of physically witnessing the test (ICC §104.3 lets the code official accept reports from approved agencies). Acceptance is at the AHJ's discretion, and the tester must qualify as an approved agency in that jurisdiction — so confirm with your inspector.
No. GasTest Log works with the ordinary mechanical gauge already on the pipe — you photograph it. Use a gauge whose range and resolution suit the test (for a 3 psi test, a 0–15 psi gauge with 0.1 psi divisions).
