1. What is a MiniTest?
MiniTest is a small, light, handheld instrument for testing vacuum supplies
and pulsators in dairies. It uses the same high-accuracy analysis as its
‘big brother’ DairyTest Professional, but in a smaller, lighter, lower-cost
format. It is intended for use by personnel with technical knowledge of
dairy operation as an accessory to a professional test kit, eg. for bench-
testing of pulsators or a quick check on dairy performance. It has only a
single vacuum port and cannot be connected to a PC or printer.
If you have difculties, we have a Freecall help line within Australia
(1800 061 167). International users should call their local distributor or
contact us via email [email protected].
2. Safety Precautions
MiniTest 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
don’t hurt people or animals.
Always ask the dairy farmer about the behaviour of the animals and
milking method used.
If using MiniTest in wet tests, always keep the unit above the test point
to prevent uid entering. Damage to the unit from uid entering the
sensor is not covered under the warranty.
3. Maintenance and Calibration
Maintenance
Clean the MiniTest with a moist cloth. Do not use cleaning agents.
MiniTest performs a self test when turned on, turning on all segments
of the LCD. If an error message is displayed (E-01 for example), or you
suspect the unit is damaged; contact innovAg or the local distributor for
further information.
Calibration
MiniTest automatically performs a zero calibration when turned on.
Do not turn on your MiniTest with vacuum connected. If the unit

© 2017 InnovAg 7
reads other than zero on start-up, a manual ‘force-zero’ feature can be
used. Refer to Section 12: ‘Troubleshooting your MiniTest’.
A complete calibration should be performed with an approved and
certied calibration test instrument every 24 months. This can be
organised by InnovAg or the local distributor.
4. The Front Panel
In Pulsation Mode, MiniTest can measure six pulsation parameters
(A+B, B, C, D ratios, rate and Max Vacuum) and provide indication of
B-phase drop and pulsation stability. In Vacuum Mode three vacuum
parameters are measured (Minimum, Average and Maximum). The
picture below shows the front panel indicators and controls.
Low-Battery Indication
If the remaining battery capacity is getting low the battery symbol will
ash. Replace/recharge the batteries.

5. Vacuum – Setting up
MiniTest can display vacuum in either kiloPascals (kPa) or inches-of-
mecury (inHg) units as required. The Units Indicator on the left-hand
side of the display will appear next to those currently set.
Changing/checking the setting.
1. Make sure the unit is turned ON and in Vacuum mode.
(Min, Avg or Max displayed).
2. Press and hold the Forward/Setup key for about 3
seconds to enter setup mode. The display wil show
unt (Units).
3. Press either the Power/Up or Mode/Down
keys to change between kPa and inHg.
4. Press the Forward/Setup key to save the changes and
return to normal operation.
Auto Exit
MiniTest will automatically exit Setup mode after 1 minute if you don’t
press any keys.
Startup Mode
Vacuum mode defaults to Average (AVG) on startup. The setting is kept
when the mode is changed to Pulsation but is reset when the unit is
turned off or the batteries run at.

6. Checking Vacuum
When set to Vacuum mode, MiniTest will display the minimum (Min),
average (Avg) or maximum (Max) vacuum level on the digital display.
Press the Forward/Setup key until the required parameter is selected.
Auto-power OFF
If there is no vacuum on the port and you don’t push any keys the unit
will automatically turn OFF after 10 minutes to save battery life.
What is it measuring?
All vacuum measurements are taken over a rolling 1.6 second period,
sampled 1000 times per second.
7. Pulsators – Setting up
MiniTest can display Pulsation Ratios (A+B, B, C and D) as either
percentage (%) of the total cycle, or in milliseconds (ms). The selected
method applies to all ratio parameters (A+B, B, C and D). Rate
measurement is xed in Cycles-per-minute (CPM).
Changing/checking the setting.
1. Make sure MiniTest is turned ON and in Pulsation mode.
2. Press and hold the Forward/Setup key for about 3
seconds to enter setup mode. The display will show
rAt (Ratio).
3. Press either the Power/Up or Mode/Down
key to set the required Ratio display method;
percentage (%) or milliseconds (ms).
4. Press the Forward/Setup key to save the changes and
return to normal operation.

Auto Exit
The tester will automatically exit Setup mode after 1 minute if you don’t
press any keys.
Saved Settings
Settings are kept until changed by you. They do not reset when the unit
is turned off or the batteries run at.
8. Checking Pulsation
MiniTest can display Pulsation Ratios A+B, B, C and D as well as Rate
(in CPM).
Press the Forward/Setup key until the required parameter is selected.
Note: Use Vacuum Mode to measure Maximum Vacuum of the pulsation
waveform.
Stability Indication
If the current reading varies from the average by more than 5%, then the
pulsation being measured is not stable. Avg will ash to warn the user
to wait until the readings settle. If Avg does not stop ashing, there is a
problem with the pulsation being measured.
B-Phase Drop Indication
If a vacuum drop of more than 4kPa is detected within the B Phase then
the pulsation is not within ISO specication and ‘B’ will ash to warn the
user.
Auto-power OFF
If there is no vacuum on the port and you don’t push any keys, MiniTest
will automatically turn OFF after 10 minutes to save battery life.

© 2017 InnovAg 11
What is it measuring?
All Pulsation measurements are taken using 4kPa thresholds, sampled
1000 times per second. Readings conform to ISO standards by averaging
over 5 cycles. A ‘rolling’ system is used where measurements from the
current cycle and the four previous ones are averaged together, which
means ISO requirements are met while the screen is still continuously
updated.
9. Software Version and Calibration Date
To display both MiniTest ‘s software version number and last calibration
date use the following sequence:
1. With MiniTest turned off, press and hold all three buttons. After
3 seconds the display will show the version number, e.g. P03
means Program version 03.
2. Release the buttons.
3. The last calibration date will then be shown in 4 steps:
CAL Calibration date follows.
23- Calibration day, eg. 23rd
-11 Calibration month, eg. November
-14 Calibration year, eg. 2014

10. Replacing the batteries
When it is time to replace MiniTest’s batteries, the battery symbol will
start to ash.
We recommend the batteries be replaced as soon as possible once the
low battery indicator starts, to prevent unreliable readings or operation.
Batteries should not be left in the unit for extended periods in case of
leakage. Use quality Alkaline or NiMH ‘AA’ rechargeable cells.

11. Repairs
DO NOT OPEN THE CASE
THERE ARE NO USER SERVICABLE PARTS INSIDE
YOU MAY VOID YOUR WARRANTY.
Defective units should always be sent to innovAg or your nearest
distributor.
Smaller repairs that can be performed by your distributor are:
• Changing parts of the housing.
• Replacing hoses
• Calibration (only if a certied original calibrator is used)
For other defects, please contact the manufacturer for further instructions:

12. Troubleshooting with your MiniTest
Before returning your MiniTest for repair, check the following:
• The unit does not turn on or won’t stay on – replace batteries.
• The battery symbol is ashing – batteries are getting low.
• MiniTest reads vacuum with no vacuum connected – disconnect
from the vacuum supply and turn it off and on again to reset the
zero. If it still does not display zero, the button sequence below will
manually force the unit to accept the pressure value on the port as
zero:-
1. Turn the unit on. Select VAC mode.
2. Press and hold the Mode/Down key.
3. Then press and hold both the Power/Up
and Forward/Setup keys.
4. After a few seconds the digists should go off
and the screen should show ‘. .’ indicating the manual zero has
been accepted. Release all keys and check the display shows
0.0.
• Damaged MiniTests should be returned for repair. There are no
user serviceable parts inside the case and opening it may void your
warranty.
• If you have a question or problem you cannot solve, contact innovAg
or your local distributor.
