4.5 Temperature Measurement
When the heater is not operating, the temperature of the workpiece can be measured by pressing MODE and START/STOP
at the same time� The LED on the START/STOP button flashes during temperature measurement� Press START/STOP to cancel
temperature measurement�
4.6 Change of Temperature Units
Press MODE and UP at the same time to switch between °C and °F� The temperature unit setting remains the same even after
disconnection from mains power�
4.7 Demagnetisation
According to the eddy current principle, the work piece is automatically demagnetised at the end of the heating cycle�
4.8 Power Level Selection
When heating bearings with the IHN010, it is important that bearings with small internal clearance or slight preload are
heated slowly� Slow heating ensures that the bearing expands slowly, thereby preventing damage to the bearing� In
addition, it is possible that the ferrite cage and seals could be heated more quickly than the inner-ring, due to their low mass�
The shape, weight, size, and internal clearances all affect the amount of time required to heat a bearing� The large
variety of bearing types precludes the possibility of providing a specific power level setting for each type� Instead, the
following guide lines are provided:
For sensitive bearings (little internal clearance) the power must be reduced�
›
Max� 20% for small bearings (positioned around the tip of the cone)
›
Max� 40% for medium-sized bearings (positioned in the centre of the cone)
›
Max� 60% for large bearings (positioned at the bottom of the cone)
