High Meter Count
- Typically associated with a bad neutral. Check the connection from the neutral wire to the meter and make sure it is solidly connected.
- The counter wires are arcing, causing the meter to count at an unusually high rate
- You really are using that much electricity, common energy hogs are space heaters, after market air conditioners, pumps, and generators
Current transformers are not polarity sensitive with the exception for bidirectional metering commonly used on solar panels
All EZ Meters are guaranteed to meet the ANSI C12.1 standard for accuracy for electric meters.
- Standard allows an error of up to 1%
- California and Maryland are states that regulate for revenue billing. Davidge Controls is certified in California, but not Maryland for revenue grade billing.
All new EZ Meters are at least 120/208 volt, 3 phase meters, Davidge Controls simply gives you the appropriate amount of CT for your application
- Line #1 and CT#1 must always be used to power the meter
CT wires have been successfully extended to 500 feet
- Do not remove CT wires from the meter without shorting the wires.
- Counter wires can be extended to a total length of 4 feet
No other current transformer may be used with an EZ Meter’s except as provided with the meter
- The meters are calibrated for specific CT’s to work with each specific meter
- Multiple wires can go through the same CT as long as they are run parallel
- The combined total current can not exceed what the meter is calibrated to handle
- Multiple CT’s can be used as long as they are connected at the meter terminal to the same phase CT’s used elsewhere
There is a 5 year warranty on all meters manufactured by and purchased from Davidge Controls
- Warranty excludes natural disasters, acts of God and improper wiring
In order for the meter to work you must supply power to Line 1. After that you can use however many CT’s as you need to measure your application
- You will need a neutral unless it is a meter specifically designed not to use a neutral
If you think your meter is reading too LOW.
- Check phasing on the meter. The power reference wire to the meter for all Lines needs to be the same as the corresponding CT. For example: If LN#1 has Phase A power, CT#1 needs to be measuring Phase A.. This is how we get the accuracy we do. If you cross up the phasing you can read a little as half the actual power being consumed.
- Double check that the wire is secured by the terminal strip on the meter.
- If you have a bad connection you may not be measuring the accurate flow
- Double check that the counter wires are secure and in the proper location. Should Comm and DSP…doesn’t matter which wire goes into which, but make sure it is NOT in the NoConn
- If you are running multiple wires through a CT, make sure they are the same phase, otherwise you are cancelling some out.
- Make sure the load you are measuring is the load being billed! Sounds silly but I can’t tell you how many times landlords thought their tenants should be higher and come to find out not all the breaker wires were run through the CT, a panel was the wrong one.
