T95
uses the constants stored in PROBE - T95
depending on location) to extrapolate the change in
reading to the expected final value when a temperature
probe is connected. The function is particularly suited to
slow temperature probes. The constants are measured via
PC software.
0.1 - 0.01
switches resolution when a temperature probe is
connected (only for Pt100 or adjusted thermcouple
probes) and facilitates with these probes measurements
≥ +300° C and ≤ -100°C with a resolution of 0.1 ° C and
measurements ≤ +300° C and ≥ -100°C with a 0.01 ° C
resolution.
Delta T
Calculates the difference between two displayed tempera-
ture values if two temperature probes are connected.
Delta P
Calculates the difference from the two pressure values,
if two pressure probes (0638.1740, 0638.1840 or
0638.1940) are connected.

aw-value
aw value measurement (water activity)
NET
Calculates NET climate index
Send
Sends current readings in ASCII format with unit to a
connected PC via connection cable 0554.0178 using the
RS232 interface. The values can be displayed, printed
and saved using the HyperTerminal program, for example.
Not all of the function buttons are allocated in every menu or
with every probe.
