A sophisticated measurement tool for Dairy Technicians. Includes accurate Vacuum, Pulsation, Vacuum Recorder and Vacuum Regulation functions. Two fluid-protected vacuum ports, colour touch screen, large memory capacity (max 5 sessions of up to 200 stalls each) and an icon-based user interface make DairyTest Lite an ideal tool for ISO testing. Reports are generated in pdf format. When plugged into a PC USB port the unit appears as a standard USB FlashDrive so reports can be easily transferred for printing and archiving. To ensure measurement integrity inbuilt diagnostics include user-initiated port Leakage and Response-time tests. Uses InnovAg’s digital calibration system with no manual adjustments for excellent long-term accuracy.

What kind of batteries can I use?
DairyTest Lite will work with either alkaline or rechargeable batteries (NiCd/NiMH); however for the best runtime, use the rechargeables supplied.

Touch Screen not responding correctly.
Turn unit off and on again, making sure nothing is touching the screen. The capacitive touchscreen auto-calibrates on power up and can get miss-set if the screen is being touched during power-up.
How often do I need to calibrate my DairyTest Lite?
Calibration interval is 12 months.
We recommend all users upgrade DairyTest Lite units to v2.5.0.

Coming in next version:
Report printing issues
Pulsation graphs are not printed correctly on all commonly-available browsers. Currently only Firefox reliably prints the report. A fix is nearing completion but requires extensive testing with every available browser for both Windows and Mac before release. A new version which prints correctly will be released soon.
Changes since v2.4.1:
Faster Pulsation measurement
The 5 cycle average for ISO6690 compliance (‘unstable’ indicator turns off) now occurs in 5s to 6s for 60CPM Pulsation. Previously ‘Stable’ was reached in 8s to 10s.
Pulsation Summary Tables added to report
The minimum, average and maximum of each pulsation parameter is shown in a table for ‘Before’ (e.g. Stall 26), ‘After’ (e.g. Stall 26*), and ‘Most Recent’. The latter will show the average of the newest-saved Stall memory, e.g. if Stall 26 and Stall 26* are saved Stall 26* will be used in the calculations. If only Stall 26 is saved that will be used. This table effectively shows the range of pulsation values for the entire dairy as it was at completion of testing. If a Stall required maintenance a ‘Before’ and ‘After’ memory should be saved, otherwise only a ‘Before’ will exist.
Improved Regulation Graph vacuum scale
The Vacuum range of the graph in Regulation mode has been changed from 0kPa – 60kPa to 20kPa – 60kPa to better highlight undershoot and overshoot issues.
Easier to delete Vacuum Recorder graphs
A ‘Delete’ button has been added to Vacuum Recorder mode so a bad recording can be deleted and restarted without having to save then delete the memory.
Hourglass shown while generating reports
While a report is being generated an animated hourglass is shown indicating the system is busy.
