7.5 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.

7.6 Change of temperature unit

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.

7.7 Demagnetisation

The workpiece is automatically demagnetised when heating is complete.
Demagnetisation will not occur if the power is interrupted or the main
switch is turned off. To use EDDYTHERM 2x for demagnetisation only,
select TIME MODE and set the time to 0.1 minute (6 seconds).

7.8 Power level selection

When heating bearings with EDDYTHERM 2x, 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 guidelines are provided:
For sensitive bearings (including bearings with C1 or C2 internal

clearance) or bearings with brass cages, do not exceed 20% power
when using the small yoke, 40% power when using the medium
yoke, or 60% power when using the large yoke.
When using the small yoke, never exceed 40% power.

When using the medium yoke, never exceed 60% power.
