The PrimeTest 300 and 350 have an onboard real time clock. This has its own independent power source - a lithium button cell - so that the time and date are not lost when the main batteries are discharged or removed from the unit.

I'm sure this is true of most Seaward testers. I know my Europa Plus has the same battery. When I first got mine (second hand) the time reset after about 10 minutes of powering down.

A design suggestion here. Why can this not be made with a battery cover and NOT soldered in,which makes the battery so it can be changed by the user without the need to open the machine - thereby voiding the calibration??

Hi Alan

It is true for all Seaward testers with memory and indeed all PAT testers with memory/time date function. The batteries last for many years means that and I cant think of any products that have user access to the real time clock battery.
For the battery to become a user serviceable part the enclosure would need to be modified to allow access - a change to the injection mould tooling and not a simple modification. Having said all that, I will bear your comment/suggestion in mind - definitely food for thought.

The other possible option would be to fit rechargeable cells which are charged whenever the unit is mains powered. Preferably to last several years off charge.
