4. Calibration & Vacuum System Check
DairyTest Lite automatically performs a zero calibration when turned on.
Do not turn on your DairyTest Lite with vacuum connected. If the unit
reads other than zero on start-up, make sure vacuum is disconnected
and turn off and on again. If it still does not read zero a manual ‘Force-
zero’ can be used. Refer to the section ‘ Troubleshooting your
DairyTest Lite ’.
A complete calibration should be performed with an approved and
certified calibration test instrument every 12 months which can be
organised by innovAg or the local distributor. When calibration is due a
‘Needs calibration’ warning will appear on the startup screen.
The warning can be temporarily overridden by performing a Vacuum
System Check
which requires a successful
Response Test
and
Leak
Test to be performed on both ports.
Enter the Factory Settings screen and the Vacuum System Check
button will show the status of Leak Tests (L1 & L2) and Response Tests
(R1 & R2). The labels are grey if the test has not been performed or not
passed.
If all labels are green the tests have passed and pressing the button will
disable the ‘Needs calibration’ warning.
