Do Measurement Settings; Do Calibration Reminder - Mettler Toledo SevenGo pro Mode D'emploi

Enter an offset value in mV between -1999.9 and +1999.9 mV.
2) Test a reference sample
1 Place electrode into the reference sample.
2 Press Start to begin the reference measurement and wait until the measurement display
freezes.
— or —
3 Press READ to manually end the measurement.
4 Press Save to enter the measured mV value as offset into the meter.

1. Salinity Compensation
A salinity correction is required in the oxygen concentration measurement of samples with a salt
con t ent of more than 1 ppt. The meter corrects automatically after you have entered the ion con-
cen t ra t ion in this menu (salinity range from 0.0 to 42.0 ppt = 42 g/L).
2. Barometric Compensation
A barometric compensation is required in the oxygen concentration measurement and calibration.
●
Auto: the meter can automatically determine the current pressure by means of an integrated
pres s ure sensor.
●
Manual: the user can enter the absolute ambient atmospheric pressure.
3. Barometric Unit
There are four barometric units available for barometric reading:
mbar
Every unit can be calculated from the standard unit Pa using the following formulas: mbar = hPa =
100 Pa Torr = 133.322 Pa atm = 101325 Pa
