Not used
(*1): Membrane check can be enabled when galvanic sensor is selected and cannot be used unless the floating ball holder,
PB350G or PB360G, is used.
(*2): The instrument will not perform salinity compensation simply by setting the salinity compensation to “1” (enabled) in Code 04,
but requires the NaCl concentration. For measurement in consideration of the salinity of a sample, first, manually calibrate with
values corrected for salinity and enter the NaCl concentration in Code 04. (See Section 6-4, “Calibration method using manual
calibration method”)
(*3): Set 60 nA for the DO70G optical dissolved oxygen sensor.
5.3.2 Temperature functions
Code 10 *T.SENS Select temperature sensor to suit the measuring probe. Refer to
instructions with DO sensor for which temperature sensor is used.
Code 11 *T.UNIT Select °C or °F for temperature display.
Code 12 *T.ADJ Adjust offset in temperature measurement when the sensor is at a stable
known value.
Code 13 *T.MAN Enable and set manual temperature compensation.
After the manual temperature set menu has been displayed, enter
temperature signals and press the [ENT] key to set. If the manual
temperature compensation is enabled, the temperature set menu is
displayed in maintenance mode.
The maximum and minimum slope values that may be entered depend on the nominal current
from service code 01.
Example : When nominal current = 3.75 μA the maximum and minimum slope calibration
values that may be entered are: Maximum 3.75 x 2 = 7.5 μA
Minimum 3.75 x 0.4 = 1.5 μA
