We have a Scantronic 9651 which has suddenly come up with a 'Batt Missing error'.

I am assuming it is referring to the 12 volt battery in the control unit. I have checked, the battery is there and it measures 13 volts, also checked the battery fuse. I tried disconnecting the battery and the mains, just in case something had got confused and needed a power reset.

Anyone seen anything like this before? Any advice would be must appreciated before I condemn the control unit to the bin.

Many Thanks.

Sounds like you have a battery fault. Test it OFF charge and not with a volt meter

Testing voltage on a battery is not a test it the current that's required .

As above, get it correctly tested or just replace.

The panel is incapable of telling lies.

Thanks Guys,

The battery has been tested out of circuit, with a load attached to it, and it is able to supply plenty of current. However I will get a new battery anyway and give it a go.

How did you test?

Resistors across the terminals?

Hi,

No I used an electronic load.

We are an electronics company and use DC loads when testing power supplies.
