3.1 Calibration

Before calibration it is important to
ensure the sensing cell is clean and
dry, as moisture and contamination
will adversely affect 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 ill 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. Press the CAL
button for a minimum of 15 seconds.
The display will show with the CAL
symbol lashing. If during testing
the CAL graphic lashes the unit will
require re-calibration.
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. The calibration data will
be stored in the memory until a new
calibration procedure is performed.
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.
