Probe Insertion
Caution
To prevent possible damage to probes, make
sure all probes put into the furnace are rated
for the temperature range used in the
calibration procedure.
Fluke Calibration recommends you use a metal
and/or ceramic fiber surface or container to set hot
probes on.
For the best stable temperature and minimum gradient, put
sample probes into the full depth of the holes in the
isothermal block or the center of the furnace tube if the
34
Note
Note
isothermal block is not installed. Variations in equipment,
probe dimension, and configuration can have an effect on
temperature stability and gradients.
A solid (unstirred) mass, as in a furnace, can have
heat loss through the probe stem. The loss
changes between probes and temperatures.
Cutouts
The Product has five cutout functions: soft cutout, hard
cutout, chassis thermostat cutout, TC and heater cutout,
and fan fault cutout. Only the soft cutout can be set
through the user interface.
Soft Cutout
The soft cutout prevents damage to the Product and
temperature probes. Use the soft cutout to turn off power
to the furnace so the probes do not become too hot.
The temperature at which the soft cutout turns off power to
the furnace can be set through the user interface. See the
Temperature Setup Menu section to learn how to set the
soft cutout temperature. Set the cutout temperature to
±10 °C of the temperature limit of the equipment under
calibration.
