Suction & Return Hose Connections
The unit comes equipped with Minimess Test Points. These seal automatically as the coupling is
removed, so the connections won’t leak during transit.
To connect the hoses, screw them onto the Minimess Test Points, hand tight only.
Make sure the hose assembly with the strainer is always used on the suction/inlet port.
To disconnect the hoses, unscrew from the Minimess Test Point. The hose assemblies do not contain
a self-seal mechanism and may drip; keep an oil absorbent spill mat ready and store hoses in a clean
plastic bag when not in use. Placing a finger over the end of the hose can prevent oil dripping out of
the test point onto the fascia of the unit.

Suction Strainer
Units are supplied with a strainer fitted to the suction tube assembly. The inline strainer has a 270
micron mesh and is used for keeping accidental debris from damaging the pump gears or clogging
other components.
The strainer must always be used, otherwise the units warranty may become void.
The strainer can be disassembled for cleaning as shown below and should be checked periodically to
ensure the flow is unrestricted.
When taking apart the strainer, note the orientation of the mesh for correct reassembly.

Operating the Unit
On/Off Switches
Units have two push button switches,
one for the pump and one for the touch
screen.
Note that because the screen regulates
the pump speed, the pump will only
work when the screen is switched on
Touch Screen Layout
The main window of the touch screen displays all information provided by the particle counter and
any other sensor that may be installed. Time and remaining battery capacity is also displayed. The
ISO code can change from white to green or red depending on the alarm limits set.

Speed can be adjusted using the “-“and “+” buttons. When moving away from this page the pump
will return to its normal speed.
ISO Alarm Limits
Alarm limits for low (clean) or high (dirty) can be set. Low refers to oil achieving required cleanliness
codes in all size categories. High refers to oil exceeding any one of the codes for particulate
contamination. When the oil is clean the ISO code on the main screen will turn green, when dirty it
will become red, between the two values the text is white.
Datalogging
The unit contains two internal dataloggers, one for the graph and one for the tests. Whenever the
unit is switched off the graph will be reset, but this can also be done from the screen without having
to switch off the unit. The main data log tied to the sensors will hold 100,000 lines of data (100,000
polls of the sensors) which equates to 138 days of testing.
To create a new log file the button needs to be held down for a couple of seconds, until a
confirmation message is displayed. This creates a new log file but does not delete the previous.
Clearing log files from the device must be done through the software, either the Particle Pal CSV
Reporting Tool or the Particle Pal Device Utility.

Battery Charging
Units are fitted with a 6S lithium battery
pack and require use of the supplied
25.5V battery charger.
A charge port on the side of the case
allows for charging of the battery, which
from a complete discharge takes
approximately 5 hours (2 hours to reach
80% charge).
To maintain the overall life of the
battery, avoid complete discharges.
If the unit is to be stored for prolonged
periods of time the battery is best left at 60% charge to maintain an optimum lifespan.
Battery Charging Unit
The battery charge unit is designed for indoor use only and should not come into contact with water,
dust, oils or grease. To prevent overheating, the product should not be covered whilst in use.
The mains socket should be easily accessible. In the event of operational error, the plug should be
immediately removed from the socket.
A fuse protects the product against short circuit and overload. If the fuse needs to be replaced, the
same type and size of fuse should always be used.
Charging Instructions
The charger has a small LED which when connected to a discharged unit will illuminate red. Once
charging is complete the LED will turn green.
Note the LED will not turn green if the unit is switched on and in use.

Fluid Viscosity
The portable analysers are designed to handle a fluid viscosity of up to 460 cSt for the small unit or
2400 cSt for the larger units. It’s possible to pass high viscosity oils through the unit if they are
preheated as per the below table.
Note that as a pre-heated oil passes though the unit it will cool, therefore increasing its viscosity and
strain on the pump.

Internal Gear Pump
The internal gear pump provides a steady flow for accuracy of results. Fluids above the rated
viscosity can cause excess motor strain and cause it to overheat or slip. It’s important to pay
attention to the grade of oil being analysed and its temperature.

Water Sensor –% Saturation (RH)
The RH option incorporates a sensor into the fluid circuit which measures water saturation as a
percentage.
The RH sensor measures water content relative to the saturation point of the liquid and outputs the
degree of saturation in the range 0-100%. A reading of 0% would indicate a fluid free of water, while
a reading of 100% would indicate a fluid that is saturated with water (see diagram below). The
capacitance sensor absorbs water molecules from the fluid which change its capacitance value, that
capacitance value is directly proportional to the saturation level of the fluid.
Since the effects of free water are more harmful than those of dissolved water, water levels should
be maintained well below the saturation point. However, even dissolved water can cause damage,
therefore every reasonable effort should be made to keep the saturation levels as low as possible.
As a guideline we recommend maintaining saturation levels below 45% in all equipment.

Water Sensor –Parts Per Million (PPM)
The PPM option incorporates a water moisture sensor into the fluid circuit of the portable analyser.
The sensor offers real time measurement of absolute water content in ppm (parts per million) and
outputs a value up to the fluids saturation point.
As per BS EN 590 diesel fuel should contain no more than 200ppm (0.02%) of water.
The sensor is calibrated specifically for use with diesel fuel, use with other fluid types will provide
inaccurate readings.
Note: If the fluid sample contains free water or has a water content of above 300ppm (cloudy/hazy
appearance) it should not be passed through the portable analyser. Samples above 300ppm will
cause the sensor to lock out. If this occurs, clean dry diesel (<100ppm) will need to be flushed
through the unit for 15 minutes to 2 hours (depending on level of exposure), where the readings will
gradually fall back within its normal operating range.

Density and Viscosity Sensor
The density and viscosity sensor uses a piezo electric device for continuous determination of fluid
density and viscosity.
To ensure accurate density and viscosity readings the fluid should be clean and maintained at a
steady temperature similar to the unit. Contaminant in the form of water or solids may cause higher
than expected readings, while an aerated fluid sample will cause lower than expected readings.

Density
The unit displays density as kg/m³, which is the same as g/cm³. To convert this to a units such as kg/l
divide the value by 1000.
Viscosity
The unit displays dynamic viscosity as mPa.s (millipascal-second). This is the same as cP (centipoise)
e.g. 100 mPa.S = 100 cP.
To convert from dynamic to kinematic viscosity such as centistokes, the dynamic viscosity value must
be divided by the fluid density.
Example:
If the unit is showing a viscosity of 150 mPa.s and density of 886 kg/m³ then, 150 / 0.886 = 169.3 cSt

High-Pressure Device (HP)
The high-pressure device allows the portable analyser to sample directly from a high-pressure line
with a maximum allowable inlet pressure of 350 bar, reducing this down to 2.5 bar at the outlet. It
has a working viscosity range of 1-300 cSt.
The High-Pressure Device can be purchased
separately and used with existing units by
connecting it to the end of the suction tubing.
While the High-Pressure Device feeds the
portable analyser with fluid pressurised to 2.5
bar, the pump must be switched on to maintain a steady flowrate.
Fluid passing out of the discharge/outlet tube should be fed into a suitably sized sample container for
disposal or emptying back into the fluid reservoir.
