All other functions/keys will remain inactive while setting this parameter. Once the heating mode is selected the parameter will set automatically.

HOO: Slow Heating for Low volume Liquid & high Accuracy (up to ll} This mode is basically for Lower volume i.e. Up to ll. The accuracy for this mode is very High, so it is 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.
H01 : Slow heating with High AccuracyThis mode is very useful for the solutions which are very sensitive to a change of temperature. After setting all parameters when user presses “Start”, the initial temperature of device will rise quickly to a point below the set value of temp., 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
H02 : Fast heating with High Accuracy high accuracy of+/-1 ·c.This mode is useful when the user wants to heat the solution quickly. 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 the set value. Initially, the temperature may vary up to +/-15°C. After stabilizing, the temperature of the plate will remain constant with
H03 : Rapid Heating with OvershootThis mode of heating is useful when user wants to heat the solution rapidly without the concern of accuracy of temperatre. 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.
H04: Rapid Heating for High volume Liquid (2L-SL}This mode is similar to H03 mode, but it is basically for high volume i.e. 2-SL. After setting up the parameters if the ser 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.
HOS: Rapid Heating for High volume Liquid (6L-10L)This mode is basically for higher volume i.e. 6-10L. 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 to the set value.

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.
