LaMotte DO 6 Dissolved Oxygen Meter - Manual (Page 38)

7.8 (DPr.7) Dissolved Oxygen Parameters
This Set Up menu allows you to set the barometric pressure and the salinity
value of the sample to be measured. You are given the option to use mmHg or
kilo Pascal barometric pressure units. The Salinity value to be entered will be
based on ppt and is available in mg/L (ppm) Concentration Set Up menu.
The Set Up menu for barometric pressure correction is “A.Hg” (for mmHg)
and “A.PA” (for kilo Pascal) whereas the Salinity menu is indicated as
“b.SAL”.
7.8.1 Pressure Setting Adjustment
1. Switch off your meter in mg/L (ppm) Concentration mode.
2. While pressing and hold the MODE key, switch on the meter by pressing
the ON/OFF key.
3. Once the ON/OFF key is released, the meter will enter the Set Up menu
by displaying “SEt.P”. By releasing the MODE key, the display will show
the configuration menu “COF.1”.
4. Press the
p and q keys to scroll through the Set Up main group menu till
the display shows “DPr.7”.
5. Press the HOLD/ENTER key and the meter will enter the barometric
pressure unit selection menu with the display showing either the “A.HG”
mode or “A.PA” mode.
6. Use the
p and qkeys to toggle between the barometric pressure units and
press the HOLD/ENTER key to confirm selection.
7. Use the
p and q keys to set the pressure value and press the
HOLD/ENTER to confirm the setting. A confirmation indicator “CO” will
be displayed for 1.5 seconds before the meter shows the next display of
Salinity setting “b.SAL”. If the Set Up menu is derived from other than the
mg/L (ppm) Concentration mode, the meter will return to the Set Up
subgroup menu “DPr.7”.
8. Press CAL key to return to measurement mode, or continue to make a
salinity setting adjustment.
