(Equal to +/- 10 ℃) . In this function display, 1 degree equal to 0.1 ℃

adjustment.

E. For example, if operator’s thermometer displays 98.5℃ and Block Heater

shows 100℃. Operator shall press down button of Temperature setting to -15
( 98.5-100= -1.5℃ ) . After 3 seconds without any further action, display will

Block Heater. If the display value still differs from thermometer, repeat the

OFFSET function setting again.

F. Care and maintenance

Blocks shall not be touched while still hot. Operator shall not directly pour

water/liquid/ice on the hot block/ block heater to reduce the temperature of the heating

surface. It may cause damage to the instrument and fast-evaporated water/ liquid may be

harmful to the operator.
