First switch on the Main Switch locate on the front panel of the equipment.
NOTICE: It is forbi en to use the evice without filling it with water. It coul cause evice estruction an staff injury.
The evice warns you if there is not enough water insi e the bath. It is necessary to use electrically con uctive liqui .
If wou use non electrically con uctive liqui then the evice will notify all the time that there is not enough water
insi e the bath even if it isn’t true. If you use istille water in the laboratory just a a pinch of salt (NaCl) an you
will get electrically con uctive liqui .
Switch on the cooling on-off switch except for the main switch in the cooling bath. There is a cooling thermostat just
next to cooling on-off switch an we o reccomen to leave its value as prea juste „value 5“
Warning! Do not exceed the temperature+30 degrees Ce sius in the coo ing bath otherwise the coo ing system can
be irreversib y damaged!!!!!

The bottles can be put in only into the bottle hol er which makes part of the supply. If you put them insi e without
the bottle hol er the bottles may move in the bath an the stirrer can be amage .
The stirrer is controlle with the help of the switch „Stirrer“. We reccommen to leave the stirrer always switche on
(in the position I) in this way the stirrer will be controlle (switch on/switch off) with "Main switch". Once the main
switch is switche on the stirrer is switche on automatically too.
One chip microprocessor is use to control the evice. The algorithm is save in the program. Program is controlle
with the help of 7 keys of the membrane keyboar which is locate on the front panel of the equipment. The report
about the operating con ition can be observe on the 2 lines of the isplay.

After switching on the equipment there is 1-CUBE name an the version of the control programme appears on the
isplay, they isappear after a while an the the text THERMOSTAT appears on the isplay. Once you finish working
switch off the evice with the help of the Main switch.
Control algorithms:
The following control algorithms PROFILE, THERMOSTAT, CALIBRATION can be run with the Water Bath
During the process the following information are automatically isplaye on the isplay.
1. ine:
The require temperature is isplaye .
2. ine:
Information about time given in minutes an instantaneous real working temperature.

Adjustment of the required temperature or time:
The require temperature or time in the metho s (menu) THERMOSTAT, CALIBRATION an PROFILE are a juste by
pressing keys plus + (to increase the value) or minus – (to ecrease the value). First the require value is change of
tenths of egree or 1 secon s, after ten changes (ten presses of key) the require value is change of egrees or 10
secon s, after ten following changes (ten presses of key) the require value is change of 10 egrees or 100 secon s
etc. Once you have a juste the require ata push the key OFF to save it into the memory, after this step the text
THERMOSTAT appears again on the isplay.
Metho Thermostat:
This algorithm allows to a just any require temperature an the Water Bath maintains the temperature for the
require time. The evice has save the last value a juste temperature that was regulate . If you o not want to
change the value of the temperature start the algorithm itself by pressing the key ON. The text: REQ.CONTROL:
appears on the first line of the isplay, there is the time in minutes „min=“an the real temperature „T=“ in
0
C on the
secon line.
If the set temperature oesn’t suit you an you nee to change it you have to a just the require temperature before
you press the key ON. The require temperature is set with the help of keys plus + (to increase the value) or minus –
(to ecrease the value) – see the paragraph above: Adjustment of the required temperature or time: in the chapter
Contro a gorithms. After setting the require temperature press the key OFF an in that way the require
temperature is save an the text THERMOSTAT appears again on the isplay. Now you can start the temperature
control running by pressing the key ON. The algorithm is stoppe by pressing the key OFF. If there is not enough
water in the Bath the text „add water“ appears automatically on the isplay an it will isappear once the water is
a e .
Method PROFILE:
This algorithm allows to a just any require time behaviour of temperatures. It is possible to a just as many as 7
points efine with time an temperature coor inates. After choice of the item PROFILE in the main menu with the
help of the key ROTATION one can start the algorithm itself by pressing the key ON.
After 1 sec the text: START ON:
OTHER PARAMETERS: appears on the isplay.
If there has been alrea y set the temperature curve before, one can use it again (because it is save in the internal
memory) by hol ing the key ON at the time when the text: START ON:
OTHER PARAMETERS: appears on the isplay.
If there hasn’t been set the temperature curve yet or it is necesary to set it in a ifferent way, one waits about 1 sec
till the text SET UP THE CURVE appears on the isplay. After that the text: time of point 1= appears on the first line an
one sets the time in minutes on the secon line. Time is set with the help of keys plus + (to increase the value) or
minus – (to ecrease the value) – see paragraph: A justment of the require temperature or time: in the chapter
Control algorithms. After setting the time of point 1 press the key OFF an in that way time of point 1 is save in the
internal memory an after that the text: time of point 2= appears on the first line an one sets in the same way the
time of point 2, the time of point 3, the time of point 4, the time of point 5, the time of point 6, the time of point 7.
After setting the time of point 7 press the key OFF an the text: temp. of point 1= appears on the first line an one
sets the temperature in
c
C. on the secon line. Temperature is set with the help of keys plus + (to increase the value)
or minus – (to ecrease the value) – see paragraph: A justment of the require temperature or time: in the chapter
Control algorithms. After setting the temperature of point 1 press the key OFF an in that way temperature of point 1
is save in the internal memory an after that the text: temp. of point 2= appears on the first line an one sets in the

9
same way the temperature of point 2, the temperature of point 3, the temperature of point 4, the temperature of
point 5, the temperature of point 6, the temperature of point 7 an by pressing the key OFF the control of the
a juste curve starts running. There is isplaye the require temperature on the first line of the isplay an the time
runne off from the beginning of the test an real temperature on the secon line of the isplay. The algorithm is
stoppe by pressing the key OFF.
