3 AfiMilk MPC Installation Manual
7 Milk Meter Calibration
Afimilk MPC is calibrated in the factory to ensure milk measurement results within the
required accuracy ranges. However, since installation environment may affect milk
measurement accuracy,
Afimilk MPC requires calibration at installation.
Three calibration procedures are described in this chapter:
1. Calibrating Electrodes
2. Air intake compensation
3. Accuracy adjustments
(on farm calibration)
7.1 Calibrating Electrodes
Three electrodes in the milk meter
body are the measuring probes of the
meter. Although electrodes are
calibrated at the factory, cable and
connection resistance may affect their
accuracy. Electrodes calibration
compensates for resistance of the lines
and therefore, it is necessary to
calibrate the milk meter after
installation.
Electrodes calibration procedure is
performed with a 100Ω (±0.1%)
resistor. During calibration, the
resistor is connected between
electrodes to test and calibrate them.
Afimilk offers a calibration tool for the
technician incorporating the resistor
and probes for hooking to the
electrodes (See below).
7.1.1 Milk Meter Electrodes Calibration tool
The easy to use calibration tool is built of an encased resistor
connected to two socket connectors used for plugging on the
calibrated electrodes.
