Hi,
I have had my HPS10 for about 10 months and at first it was working fine. Having put it down for a while I have come to realise it doesn’t seem to display signal anymore. Below is a list of symptoms and observations:
-Unit turns ON fine, display is working.
-Features for calibrating and adjusting display scales triggers etc work fine.
-Unit is set to ‘RUN’ and not on hold.
-Test signal shows <3mv deviations (basically just no signal)
-Using a DVM I can check that the probe connections are not broken its fine + and -.
-Followed trouble shooting guide checking scales and performing long reset.
-Fresh batteries checked.
-Run from DC supply, no change.
-Connecting a variety of non changing signals e.g. 5VDC, 9VDC… no signal change.
What might be the problem?
If it has been damaged/is damaged what might cause this to happen?
If there are no simple fixes how can I return the unit to Velleman for repair?
Many thanks for any help.
When it was working it was so handy I really want to get it up an running again.
Cheers,
Nick
