- Pressure test records: the strength test and the tightness test, with the hold time and the result.
- Evacuation records: the vacuum, the hold time and the result, printed on the certificate.
- Electrical checks on the certificate too: R1+R2, Zs, RCD trip time and polarity. Service reports. Every document printed on your name.

Questions
What paperwork does it make?
Commissioning certificates, tightness test records, service reports, leak check records and waste transfer notes.
Do I fill it in twice?
No. The customer, the site, the units and the readings come from the job. You add the test figures as you go.
Does it record the evacuation?
Yes. The commissioning step records the vacuum, the hold time and the result, and the certificate prints them. Where we hold the maker's steps for that unit, it shows how to set its vacuum mode.
Whose name is on it?
Yours: your logo and your firm's name. LatterHQ isn't on it.
Is the pressure test checker free?
Yes. It works with no account. The records printed from the job are Pro.
