4.6 Dissolved Oxygen Calibration in mg/L (ppm) mode
Calibrating the meter to 100% in saturation mode will also calibrate the mg/L mode at the
value in mg/L corresponding to 100% saturation. This should produce acceptable results in
most applications.
This meter also lets you make a calibration adjustment in mg/L (ppm) mode without affecting
your % saturation calibration. To select between mg/L and ppm units, see page 46.
NOTES ON MG/L (PPM) MODE CALIBRATION
• During mg/L (ppm) measurement and calibration, the meter adjusts to the
barometric pressure value that is programmed into the meter. It also adjusts to
the salinity value that is programmed into the meter.
• You can change the barometric pressure value and salinity value in the mg/L
(ppm) SETUP mode (see Section 8.6 -- P1.0 (dPr): Dissolved Oxygen
Parameters) for directions).
• Whenever an error occurs during calibration, the ERR indicator appears in the
lower left hand corner of the display.
