Page 6: What Is Dairytest Lite
2. Safety Precautions DairyTest Lite is intended to be used in the milking stall – always allow for the unpredictable nature of animals. During the measurements, sharp needles may be used – take care they do not hurt people or animals. -
Page 7: Calibration & Vacuum System Check
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. -

There are 2 memories per pulsator/stall, 8 and 8*. Select stall. The state of each memory is shown by Memory saved. No alarms. Memory saved. Alarms. DairyTest Lite will display the current reading as data and graph. Readings outside alarm limits will be highlighted. © 2021 innovAg... - Page 22 DairyTest Lite calculates pulsation data to ISO standards. The ‘unstable’ icon is shown if values have not yet settled when changing between pulsators. The display layout is saved and used for the next measurement. The pulsation memory number (stall) can be selected in the table view.
- Page 23 In data mode selecting a specific measurement will display it in large digits. Pressing again will return to the data mode screen. In graph mode, DairyTest Lite will automatically set the time to 1.6 sec or 3.2 sec as required to show an entire pulsation cycle.

Some screen items such as pop-ups may not be saved. When DairyTest Lite is plugged into a PC the file will be visible in the format ‘dtl-xxxxx.bmp’. 9. Leak Test The Leak Test checks if there is a leak in the internal tubing. -
Page 29: Response Test
The Response Test checks each port is responding quickly to changes. Test one port at a time by producing >45kPa. Quickly pull the tubing off the port and the vacuum response will be automatically calculated. Each port should have >5000kPa/s response time. © 2021 innovAg... -

At the bottom of the report index screen click the “Contact InnovAg” link. This will open an email with the unique electronic serial number of the DairyTest Lite in the title. -
Page 32: Replacing The Batteries
14. Replacing the batteries When DairyTest Lite’s batteries need replacing the battery symbol will flash. We recommend the batteries be replaced as soon as possible once the low battery indicator flashes to prevent unreliable readings or operation. Batteries should not be left in the unit for extended periods in case of leakage. -

Questions and answers
What is B.Drop and how is it calculated
B.Drop (B-Phase drop) refers to the decrease in vacuum during the B-phase of the pulsation cycle. The document does not provide a specific formula for calculating B.Drop, but it is listed as one of the pulsation parameters measured by the DairyTest Lite. It is likely calculated based on the difference in vacuum levels during the B-phase, using the high sample rate (1000 samples/sec) and accurate timing provided by the device.

B. DRP - что за параметр?
The B-Phase drop (B. DRP) parameter for the innovAg DairyTest Lite refers to a measurement related to the drop in vacuum during the B-phase of the pulsation cycle. Specific numeric details for B. DRP are not provided in the context, but it is listed as one of the measured parameters in the system.
