11.5 Changing the temperature unit of
measuerement from °C to °F
To toggle the unit of measurement for temperature readings
from °C to °F and back again, proceed as follows:
• Switch off the unit at the main ON/OFF switch. (The residual
heat display should no longer be enabled. See, Residual Heat
Warning (HOT)
• Hold the "Mode" and "Temp" membrane buttons pressed
down and switch on the main ON/OFF switch. After approx. 5
seconds the display will begin to flash. Release the membrane
buttons.
• Temperatures will now be displayed in the unit of measure-
ment selected. Temperatures in the memory will be converted
accordingly.

Setting the safety temperature

Setting and/or changing the safety temperature is only possible in
the „A"-mode of operation.
The safety circuit is set as follows:
Switch instrument on with mains switch on the left side of the
instrument.
As soon as the display shifts to SAFE H (safety temperature
limiter of the heatin plate) (SV is blinking), press the foil key
"Mode"(SV is blinking no longer), keep this foil key depressed
and set the requested safety temperature with the TEMP
rotary knob. The set safety temperature (e.g. 100°C) is dis-
played. After releasing the foil key "Mode", SAFE H OK is dis-
played for about 2 seconds, and the safety temperature is sto-
red this way.
When the display changes to show SAFE P (safety temperatu-
re limit for external sensors) (SV flashes), press the "Mode"
membrane button. The SV will stop flashing. Hold down the
"Mode" membrane button down and turn the TEMP knob to
set the safety limit temperature required. The safety tempera-
ture (e.g. 60°C) will be displayed. Release the "Mode" mem-
brane button. After approx. 2 seconds, the message SAFE OK
34
will be displayed to indicate that the safety temperature has
now been stored in the memory.

Function stirring

The motor speed is set on the rotary knob "Mot", (0 and/or. 50
to 1500 1/min in steps of 10 1/min each). "SV" is blinking.
The function "stirring" is started and stopped with foil key
"Mot".
If the function stirring is started, the motor runs smoothly to
the set speed, and the LED "Mot" beside the imprint "Mot
1/min" shines green.
The display changes to real speed display.
12.1

Intermittent mode

If Intermit mode is active, "On IntErmit" will be displayed when
the device is switched on.
The intermittent mode interrupts the stirring cycle at regular
intervals. For example, if the stirring function is switched on
with the setpoint speed set at 1 rpm the stirring cycle will be
interrupted for approx. 10 seconds after a cycle time of 60
seconds. The cycle time and the length of the interruption can
be modified via the serial interface (see section 14.1).
The stirring bar breakaway monitoring function cannot be
enabled when the intermittent mode is enabled.
The intermittent mode can also be used with the special small
stirring bars. These can be used when the stirring bar breaka-
way monitoring function is not enabled and will continue to stir
the medium even when the stirring bar breaks away. These
stirring bars are picked up once again when the speed drops
cyclically.
