Parameters: Temperature - ProMinent DULCOMETER DMT Series Operating Instructions Manual

DMT settings
Two different test options are available:
Comparison
with buffer You can check the probe in the first menu option by measuring the redox
potential of a buffer solution:
The suggested "buffer value" (the redox potential for the buffer solution) is
220 mV or 465 mV. This value can be changed. The device compares the
buffer value with the measured variable and displays an error message
"faulty probe !!" if the difference is greater than 40 mV.
Probe
resistance The probe can be checked in the second menu option by measuring the
electrical resistance between the electrodes of the probe (must be dry):
It is particularly important that there is no residual moisture adhering to the
probe.
If the resistance measured is less than 2 MΩ the device will display the error
message "faulty probe !!".

7.1.5 Parameters: Temperature

Depending upon the "temp. meas." general setting you have the following
options:
7.1.5.1 General setting: Temperature measurement = automatic
The actual temperature measured is displayed under "meas. val.".

NOTE
• The DMT automatically detects whether a PT 1000 or
PT 100 is connected.
• If there is no temperature gauge connected the
temperature measurement should be set to "none"
or "manual" (see chapter 7.1.7 General settings).
Select the unit of measurement for temperature
Enter the difference ∆t under "offset" to a reference temperature
measurement (see chapter 7.5.5 Calibrating the Pt 100 temperature
gauge).

C or F under "unit".
