3.3 Basic Operation
1. Add 3 to 4 drops of mineral oil or other heat transfer fluid to each of the 6
probe wells. The oil improves the thermal interface between the probes and
the probe well.
2. Be sure to have the unit in a tilt position during operation so that the mineral
oil does not drip out of the unit. (See Figure 4).
3. Place the ice point reference cell on a surface, leaving at least 2” space around
the unit. Never obstruct any of the air vents on the unit. Be sure that the
environment is between 35.6 to 90 °F (2 to 32.2 °C) and no higher than 90%
RH, non-condensing.
4. Plug in the unit’s power cord, being sure to use a socket with a ground lug.
Insert reference probes into the probe wells, being sure that the probe tips are
making contact with the bottom of the wells. Allow 30 minutes for the
temperature to stabilize at “freezing point.”
5. The probe wells are electrically connected to “earth ground” the the 3-wire
power cord. Never defeat the grounding lug. Always use an outlet equipped
with a grounding socket.

NOTE: NOTE:
The greater the number of probes inserted into the ice point cell the greater the thermal
load on the TRCIII-A. While the unit is designed to maintain “freezing point” for 6 probes,
performance could be compromised at elevated ambient temperatures.
3.4 Applications
An ice point reference cell is most commonly used in temperature measurement
instrumentation calibrations. The function of the ice point reference itself in such
a system is to provide a highly effective cold junction between a
thermocouple and a DMM. The cold junction assures that there is no EMF
generated at the junction between thermocouple leads and the DMM input.
In practice, this is achieved by connecting thermocouple leads to copper leads
via TRP probes which have been inserted into the ice point reference cell.
Figure 5 shows the ice point in as it is used in the field. Calibration of the system
consists of comparing the temperature of the standard probe, which is measured
in millivolts by the 5
instrument. Note that in Figure 5, J type thermocouples were chosen for
illustration.
1
⁄2 digit DMM, to the temperature shown on the temperature
It is more desirable to connect the DMM to the probe that it will normally be
used with during operation.

Operation
The “System Calibration” procedure would be as follows:
1. The temperature instrument is first electronically calibrated to its
specifications following the procedure in the Operator’s Manual.
2. The temperature probe is then compared to the “Standard” probe at various
temperature points requested.
3. A Certificate of Calibration is issued with a listing of the deviations from these
points to the “Standard.”

Figure 6 shows another common setup involving an ice point reference cell.
Here, a millivolt source is used to simulate a thermocouple’s output. The
copper lead wires are then interfaced to the iron-constantan lead wires via the
TRP probes. The TRP probes are, in effect, a cold junction since they are inside
of the ice point reference cell. The temperature measurement instrument can
now be calibrated.
