While changing Temp  Unit, the respective value will be rounded off for the converted unit & will display. Each unit selected will be indicted by respective LED.
11.7 HEATING MODE
6 different heating modes can be set when on home screen.
By long press “TEMP/MODE” button, setting display will blink and shown as HO3 as default, by rotary Knob one can switch between – H00, H01,H02,H03,H04 and HO5. All other functions/keys will remain inactive while setting this parameter. Once the heating mode is selected the parameter will set automatically.
NOTE: Temperature accuracy is claimed as per water, if liquid medium changed the accuracy may change.

1. HOO: Slow Heating for Low volume Liquid & high Accuracy (up to 300ml)
   This mode is basically for Lower volume i.e. Up to 300ml. The accuracy for this mode is very High, so itis not suggested for higher volumes. After setting up the required parameters, if the user starts the operation the temperature rises Slowly & stabilizes to  the set value.
   NOTE: This mode is design for zero over shoot of heating liquid, it will take time if the liquid volume increase or liquid type changes.

2. HO1 : Slow heating with High Accuracy (300ml to 800ml)
   
   This mode is very useful for the solutions which are very sensitive to change of temperature, it is basically for volume above 300ml to 800ml.
   After setting all parameters when user presses “START”, the initial temperature of device will rise quickly toa point below the set value chternp.,E then the temperature will rise slowly with high accuracy to set value & once it attains the set value then the  temperature will remain constant for the remaining time with the high accuracy of +/-1°C inwater.
   NOTE: If the Liquid media change than accuracy may differ from specified.

3. HO2 : Fast heating with High Accuracy (800ml to 2L)
   This mode is useful when the user wants to heat the solution quickly, it is basically for volume above 800ml to 2L volume. In this mode after setting all parameters when the user presses “START”, temp. of unit rises quickly to the set value point & then it  stabilizes to setvalue. Initially, temperature may vary up to +/-15°C. After stabilizing, temperature of the plate will remain constant with high accuracy of +/-1°C.
   
   

4. HO3 : Rapid Heating with Overshoot (1L to 2L)
   This mode of heating is useful when user wants to heat the solution rapidly without the concern of accuracy of temperature, it is basically for volume above 1L to 2L . In this mode after setting all parameters when user presses “START”, initial temperature  of device will rise very fast to the set value of temperature and once it reaches the set value device will slowly stabilize the temperature to the set value. In this mode, heating will be much more rapid then previous two modes and possible overheating could  be up to+/-20°C.

5. HO4: Rapid Heating for High volume Liquid (2L to 5L)
   This mode is similar to HO3 mode, but it is basically for high volumei.e. 2L to 5L. After setting up the parameters if the user starts the operation, the temperature will rise with high rate and will gradually stabilize to the set value. In this mode the accuracy  is not that accurate as attained in the previous modes. 
   

6. HO5: Rapid Heating for High volume Liquid (6L to 20L)
   This mode is basically for higher volume i.e. 5L to 20L. The accuracy for this mode is very low, so it is not suggested for lower volumes. After setting up the required parameters, if the user starts the operation the temperature rises rapidly & stabilizes tothe set value.

11.8 SPEED FUNCTION
To set speed, press “SPEED” button on home screen indicated by speed LED flashing on. Speed can be set by rotating the knob in proper direction for increment or decrement ranging from 0-2200 RPM in the range of 10 RPM of increment or decrement to the  parameter. Default RPM is always be as last set RPM. Heater can work even at 0 RPM. After adjusting the speed, will save automatically once the screen stops blinking.
