Operation

3-5

3.6.2

Verifying SoftCal™ Operation

Check the status of SoftCal™ by holding UNITS for 2-3 seconds. If
SoftCal™ is not in operation, "-000-" displays.

If the first digit of the display is 1, SoftCal™ is set for below 28 K. If either
the second or third digit is 1, SoftCal™ is set for above 28 K.

3.6.3

Erasing SoftCal™ Compensations

When SoftCal™ compensations are erased, the thermometer returns to
normal operation.

1. Move the SET switch to position 1.

2. Hold UNITS until the front panel displays 0. This key is a toggle. If the

display moves in the wrong direction, release and press again.

3. Press CAL ENABLE on rear panel using a pen tip. The display changes

from 0 to "-SOF-". The alarm setpoint displays after erasing SoftCal™
compensation.

4. Move the SET switch to position 0.
