5. Replace the cleanout plug.

6. Press the

↵

↵↵

↵

key to initiate the calibration on 15 PPM water. The word CAL

will appear on the upper row of the LCD display and the word NO will appear

on the lower row of the LCD display.

7. This is the final step for calibration at the 15 PPM level; if you wish to exit

without calibrating simply press the

↵

↵↵

↵

button. However, if you are satisfied

and wish to complete calibration on the 15 PPM level use the

tu arrows to

select the word YES on the lower row of the display and then press the

↵

↵↵

↵

button to initiate calibration.

8. Pressing the

↵

↵↵

↵

button will complete calibration. The system will automatically

return to the AUTO mode

Notes: If you wish to exit the calibration mode you may do so at any time, prior to

initiating a calibration, by simply pressing the MODE key.

It is normal for the system to count up to and display 13-17 PPM, in the AUTO

mode, immediately following the 15 PPM calibration as the calibration solution is

still in the sample tube.

7.2 Zero Adjust (0 ADJ) Calibration

In certain instances, the oil free water (seawater) leaving the bilge has different scattering

characteristics than the clear water used for calibration. The OCM has been designed to

allow for you to account for this variation by adjusting the zero calibration with your oil

free water. Follow the steps below for this calibration procedure:

1. Ensure that there is a good flow of oil-free sample to the OCM.

2. Press the MODE key once to enter the zero adjust calibration mode. The “CAL”

block will be illuminated on the display with “0 ADJ” shown on the display (see
