Function description, EXTENDED DIAGNOSTIC group
MIN T FLUID Description
Lowest fluid temperature measured since the last reset 
(RESET T FLUID function ä 177).
Display
5-digit floating-point number, incl. unit and sign
e.g. 95.3 °C
MAX T FLUID Description
Highest fluid temperature measured since the last reset 
(RESET T FLUID function ä 177).
Display
5-digit floating-point number, incl. unit and sign
e.g. 218.1 °C
RESET T FLUID Description
Reset the values in the MIN T FLUID (ä 177) and MAX T FLUID functions
(ä 177).
Options
NO
YES
Factory setting
NO
WARN T FLUID LO Description
Use this function to enter the lower limit value for monitoring the fluid temperature. This
limit value is used to generate a fault message which is intended to indicate that the fluid
temperature is changing in the direction of the specification limits of the device in order
to prevent device failure or to prevent the process from overcooling.
The appropriate unit is taken from the UNIT TEMPERATURE function (ä 102).
User input
5-digit floating-point number, including sign
Factory setting
–202 °C
WARN T FLUID HI Description
Use this function to enter the upper limit value for monitoring the fluid temperature. This
limit value is used to generate a fault message which is intended to indicate that the fluid
temperature is changing in the direction of the specification limits of the device in order
to prevent device failure or to prevent the process from overcooling.
The appropriate unit is taken from the UNIT TEMPERATURE function (ä 102).
User input
5-digit floating-point number, including sign
Factory setting
402 °C °C
TEMPRTRE ELECTR Description
The temperature currently measured at the electronics board appears on the display.
Display
4-digit floating-point number, incl. unit and sign
e.g. –23.5 °C; 160.0 °F; 295.4 K
MIN T ELECTRONCS Description
Lowest temperature measured at the electronics board since the last reset 
(RESET T ELECTR. function ä 178).
Display
5-digit floating-point number, incl. unit and sign
e.g. 20.2 °C
