LINER LIFE
BAR GRAPH
Accurate display of dairy vacuum:
• Damped to prevent display instability common with other digital
gauges.
• Fast mode (low damping) for technician use during testing.
• Auto zero adjustment.
• Manual zero adjustment.
• Display in either inHg or kPa units.
• Liner wear monitoring:
• Continuous bar-graph display of remaining liner life.
• Display of remaining liner life in %.
• Manual reset of liner life remaining, i.e. liners have been replaced
2. Installation
• Mount DVG as required.
• Connect to a power source 10 – 32VDC, 9 to 24VAC.
• Power wires can be connected in either polarity.
• The display will rst show a test screen, then 0.0
The round black sticker on the side of the DVG is an
expensive waterproof air vent that allows the case to
‘breath’. It should NOT be removed or covered.

3. Initial Setup
With the power off press and hold the button and turn the power on.
The button must remain pressed to stay in setup mode.
Manual Zero
Keep holding the button down after the calibration year is shown in
setup mode to initiate Manual-zero.
Make sure there is no vacuum on the port.
The software version is
shown eg. v5.0
Calibration month eg. October Calibration year eg. 2018
The display will ash 0.0 ve
times before the zero starts.
When it stops ashing
Manual-zero is completed.

Changing Vacuum Units and Liner Milkings
Keep holding the button down after the Manual-zero is completed
to enter unit and liner setup mode. The screen will cycle through all
combinations continuously.
Release the button when the desired setting combination is shown as
described below.
Units = kPa.
Liner milkings = disabled
Units = kPa.
Liner milkings = 1200
Units = kPa.
Liner milkings = 2500
Units = inHg.
Liner milkings = 2500
Units = inHg.
Liner milkings = 1200
Units = inHg.
Liner milkings = disabled

4. Normal Operation
Pressing the button will display
the remaining liner life as
percentage, eg. 75.3%.
Display Liner Life in %.
Holding the button down will display the software version, calibration
month and calibration year.
The software version is
shown eg. v5.0
Calibration month eg. October Calibration year eg. 2018

Fast (Technician) Mode
Keep holding down the button after showing the calibration year to
toggle FAST mode on or off. For example, if it was off it will turn on
before entry.
Reset Remaining Liner Life
When new liners have been tted the Remaining Liner Life counter
should be reset to 100% (99.9%).
Keep holding the Button down after FAST mode to initiate Liner reset
mode.
Slow response to vacuum changes can
be inconvenient when performing an
equipment test.
FAST Mode temporarily makes the unit
respond faster to vacuum changes.
FAST mode automatically cancels after
20 minutes
The display will ash 10 times before
resetting.
Continue holding the button down until
the display stops ashing and shows
99.9%

Milking - Vacuum has been higher than 20kPa (5.9inHg) for at least 20 mins.
Liner Life – Remaining life based on 1200 or 2500 milkings of 15 min each.
Unstable Vacuum Indicator
DVG will detect if the vacuum is unstable (drops by more than 4kPa
from the average) and will ash the decimal point for 5s each time a
drop is detected. The displayed reading is not affected by the drop. The
Unstable indicator is not shown in Fast Mode.

6. Demonstration Mode
If pins 3 and 4 of J1 are shorted when DVG is powered on it will go into
Demonstration
Mode, indicated by the Liner icon ashing continuously.
This mode is useful to show how the DVG works without waiting the
long times normally required for events to occur. The following times
change:
ITEM NORMAL DEMO
Wait for vacuum to stabilise at start of milking 20 min 1 min
Liner wear bars drop one by one at 1200 30h 10.8s
Liner wear bars drop one by one at 2500 62.5h 22.5s
Exit Demonstration Mode by removing the short and power cycling DVG.

7. Maintenance & Calibration
DVG requires little maintenance for years of accurate operation. If the
vacuum readings appear to be incorrect replace the small dust lter in
the silicone tube connected to the vacuum sensor.
DVG is factory-calibrated with a traceable Swiss reference vacuum
gauge (±0.05kPa). To ensure highest accuracy the calibration should be
checked every two years. Many vacuum gauges (both dial AND digital)
can have an error of 2kPa or more. Even a wellmaintained mercury
manometer can easily have an error of ±0.5kPa. If checking DVG be
careful that the other meter you are using is reliably accurate and the
vacuum is perfectly stable.
DVG can be returned to InnovAg for recalibration. Contact InnovAg or
your local distributor for the latest calibration prices.
