SKF TMEH 1 OilCheck 5

1. INTRODUCTION

The SKF OilCheck TMEH 1 measures the effect of contamination and

electro-chemical changes that occur in synthetic and petroleum

based oils. It is especially developed for engine oils but is also

suitable for gear and lubrication oils. The OilCheck is a portable

instrument which offers a two-minute alternative to lengthy laboratory

investigations.

1.1 Principle of operation

The OilCheck detects and measures the dielectric constant of an oil.

By comparing the measurements obtained from used and unused oils

of the same brand, the SKF OilCheck is able to determine the degree

of change in the dielectric constant of the oil. Dielectric change is

directly related to the degradation and contamination level of the oil

and helps the user to optimise intervals between oil changes and to

detect increased mechanical wear and loss of the oils lubricating

properties. To facilitate trending the instrument is equipped with a

numerical read-out.

3. OPERATING INSTRUCTIONS

3.1 Calibration

Before calibration it is important to

ensure the sensing cell is clean

and dry, as moisture and

contamination will adversely

effect the results. Testing should

generally be undertaken with the

unit switched in the HI position.

The Green/Red scale is mainly for

use when testing engine oils.

Step 1

Half fill the sensing cell with clean

oil (ensure that the whole surface

of the sensor is well covered with

oil). Oil of the same brand as in

the system being evaluated,

should be used for calibration.

Step 2

Run the rotary switch from the

OFF position to the HI position,

the display will complete a full

sweep and return to the zero

position. The display will show

with the CAL symbol flashing.

If during testing the CAL graphic

flashes the unit will require re-

calibration.

8 OilCheck SKF TMEH 1

Step 3

Press the test button. The CAL

graphic will disappear and one

segment will remain displayed.

The instrument has now

calibrated itself against the clean

sample and is ready to test the oil

in your system.

Note: Ensure that the CAL knob is

not pressed as this will put the

instrument back into calibration

mode and the unit will need to be

re-calibrated.

3.2 Cleaning of sensor

Remove the unused sample from

the sensor cell with a clean rag or

tissue. Clean the sensor by using

a contact cleaner solution

(penetrating, fast-evaporating,

non-residue solution), such as

LoctiteTM 7070.

3.3 Measuring

For optimum results make sure

you use a representative oil

sample and that its temperature is

not higher than 40 °C (100 °F).

Place enough oil in the sensor to

fully cover the sensor surface.

Press the test button and keep it

depressed for 10 seconds or until

the segments have stopped

moving around the display (the

display will flash to show the unit

is testing). The result will remain

on the display when the button is

released until the next test is

carried out.

To test again, clean out the

sensor well with a clean rag or

tissue. Refill the sensor well and

press the test button again. A new

reading will appear on the display.

In case an oil of another brand is

checked, re-calibration of the

instrument will be needed.

3.4 Interpretation of the

reading

Users should use the OilCheck to

monitor the change in the oils

properties and build up a picture

of oil degradation based on their

experience and own operating

criteria. Individual thresholds of

acceptability can be marked on

the unit's scale.

The red and green areas are

designed as an indicator of the

condition of an engine oil. Within

the green band the oil is deemed

acceptable and within the red

area the oil should be changed

and checked again after a short

running period to ensure no

mechanical problems are present.

4. CONTAMINATION EFFECTS

The usual contamination found in oils is caused by oxidation and acid

build up, these occur during the normal running of an engine and

should show up as a gradual increase in readings over a period of

time or distance. Other contaminants occur because of excessive

wear or mechanical failure, the main elements of which are dirt, soot,

fuel, water, anti-freeze and metal particles. These elements give a

marked increase in the OilCheck's reading and will give immediate

warning of possible resulting failure.

1. Water and anti-freeze contamination will cause a dramatic

change in the reading which will move the segments well into the

red.

2. Metal particles will also cause an extreme reading though the

display should move up in small jumps as the particles settle on

the sensor surface.

3. Fuel is harder to detect as its presence will sometimes mask the

presence of other contaminants. If the oil is only contaminated by

fuel the display will show it as a stronger reading well into the red

but the presence of water or metal will sometimes counteract the

fuel giving a reading in the green. Should an engine oil continue

to show no increase in its reading over a period of time the

possibility of fuel contamination should be investigated.

4. Changes in the viscosity of the oil will cause a slow reduction of

the dielectric constant which will be difficult to detect.

5. Changes of the acidity will typically reduce the dielectric strength

in a detectable manner.
