How do I adjust the inductor calibration?

Service: How do I adjust the inductor calibration?

If you notice your inductor weights are consistently off, or if you have just replaced a load cell or connector, you must recalibrate the scale. You can do this using the automated Wizard or by manually calculating the calibration factor.

This is the simplest and most accurate way to calibrate the inductor using the app's built-in logic.

  1. Enter Manual Mode: Tap the Manual tab on the bottom navigation bar.

  2. Start Wizard: Select the Inductor Scale Calibration Wizard.

  3. Follow Prompts: The app will walk you through taring the scale to zero.

  4. Add Weight: When prompted, add 5 gallons of water measured accurately using a standard agricultural calibration vessel.

  5. Run Drain Wizard: We highly suggest running the Drain Weight Wizard immediately after a calibration.

Method 2: Manual Calibration Procedure

Use this method if you need to "fine-tune" the calibration factor manually or if you want to verify accuracy without running the full wizard.

Part A: Testing the Current Accuracy

  1. Enter Diagnostics Mode: (Data Tab > Mixmates > Three Dots > Diagnostics).

  2. Enable Scale: Turn on the scale reading for the inductor.

  3. Tare: Set the weight to 0.

  4. Add Test Weight: Add exactly 5 gallons of water (measured in a calibration jug).

  5. Record Reading: Write down exactly what Mixmate shows for the weight.

    • The target weight for 5 gallons of water is 41.7 lbs.

  6. Clean Up: Turn off the weight reading and exit Diagnostics Mode.

Part B: Calculating the New Factor

The goal is to be within 0.1 lbs of the target 41.7. If you are outside that range, perform the following math:

  1. Calculate Error: Divide the Mixmate Reading by 41.7.

    • Example: If Mixmate showed 40.5 lbs, then 40.5 / 41.7 = 0.97122

  2. Locate Current Calibration: Go to Mixmate List > [Your Machine] > Proceed > Assemblies Tab > Inductor Assembly. Scroll down to find the current Calibration Factor.

  3. Calculate New Factor: Multiply your Error (from Step 1) by the Current Calibration Factor.

    • Example: 0.97122 x 25974.07 = 25226.54 (Round to 2 decimal places)

  4. Update: Enter this new number into the Calibration Factor field.

  5. Save: Save the Assembly and then Save the Mixmate.

Final Calibration Checks

Before finishing, verify these environmental factors that can cause weight errors:

  • Check for "Binding": Ensure no hoses or wires are pulling on the tank. Anything touching the tank "steals" weight from the load cells.

  • Level the Trailer: Ensure you are on level ground so the weight sits vertically on the load cells.

  • Wind Interference: High winds can cause weight "bounce." If the reading is unstable, try to calibrate in a sheltered area.
