Smart Splitter Calibration Guide

When to Calibrate Your Smart Splitter

Calibration ensures your Smart Splitter accurately measures power consumption. You should calibrate if you notice:

Signs Calibration is Needed:

• Unexpected tripping - Smart Splitter shuts off power when it shouldn't
• Amperage mismatch - The NeoCharge app shows different amperage than your car or EVSE displays
• After installation - Always calibrate a new installation for best accuracy
• Inconsistent readings - Power measurements fluctuate unexpectedly

How to Calibrate

Step 1: Access Calibration Settings

1. Open the NeoCharge app
2. Select your Smart Splitter from the device list
3. Tap Settings (gear icon)
4. Select Calibrate Sensors

Step 2: Prepare for Calibration

1. Start charging your EV at your normal charging rate
2. Wait at least 1 minute for the charging speed to stabilize
3. Note the actual charging amperage from one of these sources:
   • Your vehicle's charging display (most accurate)
   • Your EV charger's display
   • Your vehicle's mobile app

Step 3: Enter the True Reading

1. In the calibration screen, enter the actual amperage your vehicle/EVSE shows
2. This is your "true reading" - what the equipment is actually drawing
3. Tap Calibrate to save

Step 4: Verify Calibration

1. The app should now show amperage matching your vehicle/EVSE
2. If still mismatched, repeat the process
3. You can recalibrate or reset to defaults anytime

Why Calibration is Important

Smart Splitters use precision current sensors that can be affected by:

• Manufacturing tolerances
• Installation variables (wire positioning, cable routing)
• Environmental conditions (temperature, electromagnetic interference)
• Normal sensor drift over time

Calibration aligns your Smart Splitter's readings with your vehicle's actual power draw, ensuring:

• Accurate power monitoring
• Correct cost calculations
• Proper load management
• Prevention of unnecessary tripping

Troubleshooting Calibration Issues

If calibration doesn't resolve the issue:

1. Check physical connections - Ensure all plugs are fully seated
2. Try different charging rates - Calibrate at the amperage you use most
3. Reset to factory defaults - Then recalibrate from scratch
4. Contact support if problems persist

Pro Tips

• Calibrate at your most common charging rate for best results
• If you change EVs or chargers, recalibrate for the new equipment
• Seasonal temperature changes may require recalibration
• Don't worry about mistakes - you can always reset and start over
