Data transmission
A) In general
We are still in the working window. On the left, there is the illustration of the thermo-
meter and perhaps "No Connection" provided that the thermometer has been tur-
ned-off or disconnected.
Turn-on the thermometer or connect it. Now the message "No Connection" disap-
pears. If the message "No Connection" does not disappear, there is a problem either
with the thermometer (battery?) or with the connecting cable (safe fit?) or with the
software installation (setup error?). Start again from the beginning and try it once
more.
In the working window you can click everywhere where a "readable" button can be
seen. In the headline of the menu window you can find the following fields:
The field "File" for Save, Print or Exit for quitting the program or
The field "Real Time" (graph), a graphic presentation of the measurement in real time
(Run or Stop) or
The field "Datalogger", the transmission of the stored data from the thermometer to
the PC or
The field "View" for activating and deactivating the Control Panel or the graph or
The field "Window" for activating or deactivating different window views
(cascading windows) or
The field "Com Port" for setting up the interface if the Com 1 is "occupied"
or
The field "Help", the so-called help file with a German menu-driven operation but an
English help text or
Finally the field "Exit" (a "X" at the top on the right) for quitting the program.
In the bottom line of the working window you can follow the status of the Thermo-
logger: "On Connection" for "the connection has been established" or "Off Connec-
tion" for "the connection has been interrupted".
B) Real time graph
Click the field "Real Time" and "run". If you have a colour display or a colour monitor,
you will see four constantly writing lines that depict the temperatures T1 (in yellow),
T2 (in red), T3 (in green) and T4 (in pink) in dependence on the time T. In the following
you will find a short description of the different commands.
The two fields on the left in the real time graph window serve to fade in or fade out
the table below the temperature writing or to fade in or fade out the three fields Start-
Time, Sampling Rate and Data-No. (= continuous counter of the acquired tempera-

C2 Button assignments
a) MAX MIN for the temperature measuring input "T1"
By actuating the button "MAX MIN" you get to the recording of the minimum and maxi-
mum values. The highest and lowest temperatures are constantly detected and recor-
ded. With each actuation of the button you can read alternately the maximum value
"MAX", the minimum value "MIN" or the current measuring value "MAX MIN" (flashing).
Actuate the button "MAX MIN" for approx. 2 seconds in order to quit the function.
Note!
It is not possible to change the measuring unit during the recording of the
maximum / minimum values.
b) CLOCK for the time display
The actual date with year (centre), month, day (at the bottom on the left) and time
(hours:minutes, at the bottom on the right) are indicated with the button "CLOCK"
(after setting the time). Each press of the button is confirmed with a short "Beep" of
the beeper.
In order to set the time, proceed as follows:
Actuate the button "T1 - T2" at the same time when you turn-on the thermometer in
order to set the time. In that way you will get to the setup menu "Set".
Now actuate the button "CLOCK" (= Hold). The display for the date and the time
appears, the year is flashing. With the buttons "^" for upwards (=" REC") and "v" (="°
C/° F") for downwards you can modify the setting upwards or downwards.
Set the year and actuate the button "CLOCK" once.
Now the segments for the month are flashing.
Set the actual month (e.g. 01 for January) and actuate the button "CLOCK" once
again. Now the segments for the day are flashing.
Set the actual day (e.g. 08 for the eighth day of the month) and actuate the button
"CLOCK" once. Now the segments for the hours are flashing.
Set the hours (24-hour display) of the actual time and actuate the button "CLOCK"
once. Now the segments for the minutes are flashing.
Set the minutes and actuate the button "CLOCK" once in order to finish the setting of the
time. The display indicates for a short time the available memory (e.g. 1 5984 for 15984
memory locations). Then the display changes to the "normal" temperature display.
Now the time is set relative exactly to the minute.
c) HOLD function
With each press of the button (brief) the HOLD function is activated or deactivated.
HOLD means that the current measuring value of T1 is held until the data hold func-
tion will be deactivated. While the measuring value of T1 stands still, the temperatu-
re difference T1- T2 and the temperature display T2 continue running. It is neither
possible to change from °C to °F or vice versa nor to activate the time display or the
function "MAX MIN".
