Overview:
If the Guidewheel data looks off—even though you're receiving data—this guide helps validate whether the issue is with sensor setup or the measurement point. This article is helpful for operators and technical leads diagnosing strange power patterns.

Step-by-Step Instructions:
Was the data previously accurate?
If Yes, check for recent changes to machine wiring, CT sensor location, or site power configuration.
If No, continue with setup verification.
Check CT Sensor Connection:
Confirm that the green end of the CT sensor is fully plugged into the meter.
Inspect the CT sensor wire for damage or loose soldered connections.
Check CT Sensor Placement:
Ensure the CT sensor is attached to phase 1 power.
Ensure the CT is fully clipped closed.
Try a New Location:
Move the CT sensor to a different power lead or location on the machine where current draw may be more stable or relevant.
Power Cycle the Meter:
Restart the Guidewheel meter to reinitialize data capture.
Still Inaccurate?
Contact Guidewheel Support to further evaluate the setup and measurement conditions.
Tips & Best Practices:
Power fluctuations or VFD noise can impact data—place sensors on consistent-load circuits when possible.
If the machine has multiple motors or systems, measuring only one may not reflect total activity.
