UPDATE: I've been having an intermittant issue with the DGV unit sometimes not shutting off. I sent an email to Acumen about it:
I have a DGV unit installed for some time now, but every now and then the voltmeter wont shut off. This has happend 3 or 4 times now and this morning I came down to find the voltmeter still on from last night! This seems to be very intermittant and I was wondering if you've experienced any problems like this with the DGV units and if you know what might be causing this? Nothing has changed in my wiring since the day I installed it. I have had the battery disconnected several times. I've never had to re-prgram the unit when reconnecting the battery. Any assitance with this issue would be greatly appreciated.
Acumen's response:
Hi Dave,
Yes, we have seen it. It seems the DGV will sometimes not switch off at night. Once it has switched off, it stays switched off. We’ve changed a resistor value on the PCB which has cured this anomaly. Please get the head unit back to us David with a copy of this email and we’ll get it changed over.

When I think about when the unit would not turn off it was in fact every time at night or in my garage with the lights out.
I will be sending it back to them for a replacement. So far, top notch 1st class customer serivce from Acumen!! Both with this issue and the diode!
