Iso-Tech IDM 505 problem

[mattltm]

Sorry! I realise this is in the wrong topic!

I've recently been given an Iso-Tech IDM 505 which has a problem. When I turn it on, the device emits a continuous beep and shows "PROBE" on the display. The only setting that works is the A setting which works fine and is measuring current OK.

I've tried a reset but nothing has changed.

Has anyone come across this before? I have no idea where to start looking!

Thanks.

OK. Managed to work this one out for myself. A small reflow job on the probe terminals and it's working fine!
