Operation manual

4. Operating instructions

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 fill the sensing cell with clean oil (ensure that the whole surface of the

sensor is well covered with oil) (Figure 4-1). Oil of the same brand as in the

system being evaluated, should be used for calibration.

Figure 4-1. Calibration step 1

Step 2

Run the rotary switch from the OFF position to the HI position (Figure 4-2),

the display will complete a full sweep and return to the zero position. Press

the CAL button for a minimum of 15 seconds (Figure 4-3). The display will

show with the CAL symbol flashing. If during testing the CAL graphic flashes

the unit will require re-calibration.
