My Mag meter is not measuring properly. What can I do?

Troubleshooting: Mag Meter Measurement Issues

If your flowmeter is providing inaccurate readings or no readings at all, follow these steps in order to diagnose the problem.

Step 1: Physical Inspection

First, verify that the hardware is receiving power and a signal path exists.

Check the Lights: Are the power and signal lights lit on the meter?
Check Connections: Ensure all cabling is intact and that all plugs are seated securely in their sockets. Look for any corrosion on the pins.

Step 2: Configuration Check

Verify that the software "talks" to the correct hardware port. You can find these settings here:

Go to the Data tab.
Select Mixmates.
Select your specific Mixmate from the list.
Tap Configuration.

Check to make sure the flowmeter/mag meter is assigned to the specific Module that it is physically connected to.

[!TIP]
We recommend calling your dealer or Mixmate support to help walk you through this process, as changing these settings can affect how other components function.

Step 3: Calibrating or Grounding

If the hardware is powered and correctly assigned but the totals are wrong, it usually boils down to one of two reasons:

1. Consistently Wrong (Calibration Issue)

If the meter is always off by the same percentage (e.g., it always reads 10% low), you need to adjust the Calibration Factor using this formula:

\text{New Cal} = \left( \frac{\text{Mixmate Reading}}{\text{Actual Amount}} \right) \times \text{Old Cal}

Example: Mixmate shows 100 gallons, but your sprayer tank actually has 120 gallons. Your current calibration is 24.
$(100 / 120) \times 24 = 20$
Your new calibration factor is 20.

2. Sporadically Wrong (Grounding Issue)

If the readings jump around or are inconsistent from one load to the next, this is almost always a grounding issue.

The Cause: Stray voltage is entering the liquid stream and confusing the magnetic sensors.
The Fix: You must identify what is putting stray voltage into the liquid and ensure the system is properly grounded.

Understanding LED Status Lights

The lights on your meter provide instant diagnostic feedback.

3" Arag Mag Meters

Light Color	Meaning
Green	Liquid is present, but there is no flow.
Blue	Liquid is present and flowing.
Purple	No liquid detected (typically air).
Red	Error. Count the flashes and contact support.
Flashing Blue/Green	Grounding issue. System is not properly grounded with the external world.

How to Update Firmware

If you are experiencing communication issues, ensure your system is up to date. This process is found in the Mixmate list:

Go to the Data tab.
Select Mixmates.
Tap the Menu button (three dots) on the right side of the desired Mixmate.
Select Update Firmware.
