Wiring Check

The AcuRev 1312 meter supports a built-in wiring check function, this allows users to identify what the actual error is on the meter.  

This check uses the voltage and current phase angles to determine if there is a wiring issue. If the difference in voltage and current phase angle is greater than 30°, the meter will consider this a wiring issue.

There is a wiring check option for both the voltage and current connections.  The wiring check can be viewed on either the meter display or from the utility software.

NOTE: Ensure to use the wiring check when the meter has a sufficient load on it, otherwise the wiring check will not be accurate.

Meter Display:

To view the wiring check on the meter display press and hold the “SCROLL” button.  You will be redirected to the voltage wiring check page.

The wiring check is displayed as a sequence of 0’s and 1’s where the “U” represents voltage.

U XXXXXX, where X is either ‘1’ or ‘0'.

2. ‘0’ represents the connection is correct.
3. ‘1’ represents the connection is incorrect.

Sequence Explanation:

2. The display digits 1~3 (from left to right) would represent if a phase is not connected.  For example, Phase A Voltage missing, Phase B Voltage missing, Phase C Voltage missing.
   
3. ​Digits 4~6 represent Phase A Voltage, Phase B, Phase C voltage being connected incorrectly.
   

Press “SCROLL” to navigate to the next screen.  The second screen is the current wiring check.

The wiring check has a sequence of 0’s and 1’s like the voltage check.  The “I” at the left of the screen represents current.

I XXXXXX, where X is either ‘1’ or ‘0’

Sequence Explanation:

1. The display digits 1~3 (from left to right) represents Phase A CT, Phase B CT, Phase C CT being in the reverse direction. 
   
2. Digits 4~6 represent Phase A CT, Phase B CT, Phase C CT being connected incorrectly. (Phase Misalignment)
