ⅰ、brief introduction
thermostat water bath tank is a necessary instrument widely used for testing activities in the scientificeducational department of medicinesanitation, biology, descendiblity, environment protectionaquaculture, such as desiccation, inspissations, distillation, soakageso on. the main features are as following:
1 temperature is controlled accuratelyautomatically with digital display.
2 the container of the instrument is made of stainless steal with a super function of anti-cauterization.
3 it’s easysafe to operate.
4 a magnetic time stirrer can be installed to satisfy customer’s need to enhance its equalityaccuracy.

ⅲ、usagemaintenance
1.1 inject adequate water no more than 2/3 of its volume into the containerput it on the tableput through the electricity.
1.2 panel introduction
1. digital display to show the set temperatureconcerned parameter
2. indicator light sl green when setting the temperatureconcerned parameter ; ol red when it is heating
3. keystroke
set: to se-lect the parameter
up: to turn up the parameter
down: to turn down the parameter
1.3 when electrified, the panel first flashesdisplays dfs then shows 8 to test the numeral tube
1.4 press the set key oncethe sl light is on,you are in the state of setting the temperature. press up key oncethe temperature rise 0.5℃
1.5 press the set key a second time, the primacy shows dyou are in the state of controlling the temperature in advance, the adjusting range is from 0℃ to 5℃ (for example: the setting temperature is 50℃, if the deviation is 0.5℃ ,set d to 0.5 to prevent from erring.it will stop heating when it reaches 49.5℃; if the set temperature is 90℃the deviation is 1℃ then set d to 1it will stop heating when it reaches 89℃)
1.6 press the set key a third time, the primacy shows c or -,it’s time to adjust the deviation. you can set in the range of -9.8—+9.9℃. for example: when the showed temperature is 0.5℃ lower than the needed temperature, set c to 0.5℃; when the showed temperature is 0.5℃ higher, set c to -0.5℃
1.7 press the set key a fourth time to test state, if you have a preset temperature, it goes to control automatically. after the temperature is set, the controller will go back to work if you don’t press the set key in 5 seconds
1.8 press the set key for 5-8 secondsthe instrument recover to 00.0℃. when you set the temperature for the first timethe temperature is abnormal, please reset.
1.9 when work is done, press the set key for 5-8 seconds the temperature controlling system would reset automatically to 00.0℃turn off the powerif you forget to press the reset keyturn off the power directly, the temperature controlling system will remember the previous temperature after restart
1.10 if the instrument is not used for a long time, water should be get rid ofthe instrument should be cleaned with soft cloth.
note: no heating when there is no water in the container
