Do Calibration Reminder; Endpoint Formats - Mettler Toledo SevenGo Duo pro SG68 Instrucciones De Manejo

Salinity Compensation
A salinity correction is required in the oxygen concentration measurement of samples with a salt content of
more than 1 ppt. The meter corrects automatically after you have entered the ion concentration in this menu
(salinity range from 0.0 to 70.0 ppt = 70 g/L).
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 pressure
sensor.
Manual: the user can enter the absolute ambient atmospheric pressure.
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

6.7 Endpoint formats

Auto
With the automatic endpoint the selected stability criterion determines the end of an individual reading
depending on the behavior of the sensor used. This ensures an easy, quick and precise measurement.
1 Place sensor in the sample.
2 Press READ.
A appears on the display.
The measurement ends automatically when the measured value is stable.
If READ is pressed before the signal is stable, the endpoint format changes to manual
Manual
Unlike Auto, user interaction is required to stop the measurement reading in manual mode.
1 Place sensor in the sample.
2 Press READ.
M appears on the display.
appears on the display to signalize measurement stability.
3 Press READ to end the measurement.
Timed
The measurement stops after the set time, which can be set between 5 s and 3600 s.
1 Place sensor in the sample.
2 Press READ.
T appears on the display.
appears on the display to signalize measurement stability.
The measurement ends automatically when the set time period expires.
If READ is pressed before the signal is stable, the endpoint format changes to manual
