Author Topic: Any Digital Electric Usage Meter Experts - Settings causing false readings? Lyle Romer Phenomenal Film Handler Posts: 1400 From: Davie, FL, USA Registered: May 2002 posted 04-27-2009 06:12 PM                     Basically, at one of our locations the electic meter (A Power Measurement Ion 6300) is reading usage that is about double what the building should use. It will be very expensive to install a redundant meter to try and figure out what is going on. Do the solid state digital electric meters have any settings that can cause false readings like this? I know that they should be just an induction based ammeter and a voltmeter combined with some kind of processor. I guess my question is are there any settings where you need to tell the meter the service voltage or anything like that? Besides comparing the usage to other locations, I actually charted out the consumption of everything (down to each light bulb) in the building and no matter what kind of ridiculous hours I put in for operation it doesn't come close to what the meter is saying we use.  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 04-27-2009 06:51 PM                        The Ion 6200 Quick Start Guide shows some configuration options that might affect accuracy (although I am not an authority). Can't seem to find similar info on the 6300.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 04-28-2009 12:52 AM                     Is this the meter your power company is using for your billing? Or is it just a secondary metering for usage? In any event, there are parameters that affect the scaling or ratio of usage to readout. ie with a factor of 2.0, the meter will read half the actual usage, with a factor of 0.5 it will read double the actual usage. (Edited as I had the descriptions backwards) If this is NOT your power company's meter, you can take a look at the setting "tc1" and see if it's set to 1.0 WARNING: If this is the meter your power company uses for billing, DO NOT, EVER, even try to access any of the settings!! Many of them report such attempts or keep a data log and you will get in big trouble with the power company for tampering!! Contact your power company and request that a meter technician check it out.

Is it some kind of switch or is it set in software? If switch, where would it be located?  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 04-28-2009 09:51 AM                        Test Test Is this thing working? Did you not click on the link to the 6200 info?  |  IP: Logged Richard Hamilton Phenomenal Film Handler Posts: 1341 From: Evansville, Indiana Registered: Jan 2000 posted 04-28-2009 10:53 AM                     866-466-7627  |  IP: Logged Bill Enos Film God Posts: 2081 From: Richmond, Virginia, USA Registered: Apr 2000 posted 04-28-2009 11:34 AM                     When the power company replaced our old meter (installed 1946) a year ago with a new digital one, the tech spent about 30 minutes setting it up for our use. Then connected a test instrument alongside it for 30 minutes to verify accuracy. Before he started he also ran an accuracy test on the old meter, it was within specifications. We were told that if a difference in the bill was noted to call for a recheck. No change has been noticed.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 04-28-2009 12:39 PM                     Lyle, it would be set in the software. Did you not read my first post? I repeat, if this is your power company's meter, DO NOT touch it!! You can and will be charged with power theft, and/or meter tampering and both can be charged as a FELONY if the power company wants to. I think you're under FPL there and they are very big on prosecuting meter tampering. Call them to send a tech out to check it for accuracy!  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 04-28-2009 02:48 PM                     Also most newer digital meters are reffered to as Smart Meters because they change the billing rate based on the rate that the utillity is actually paying for the electricity at that given moment. Up here most people have noticed an almost doubling of their bills since most consumers use the biggest loads (stoves) during that peak demand period  |  IP: Logged
