not bad at alli have the same one pictured and you can get it for 10 bucks shipped....i'll throw it with the amp...lmk...lights up green, and it about 1/10th of a volt difference than my dmm...pretty accurate.
If you go to the display options, you may have a battery voltage display available??? My 880 has one... I haven't had a chance yet to test it and see if it is actually accurate though. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gifDeck: Pioneer DEH-5900IB
