3.1 Equipment Required
•
Precision mV source, with 0.001 mV resolution and ±0.002 mV
accuracy
or
•
Precision DVM with ±0.002 mV accuracy and an adjustable mV
source with 0.001 mV resolution
•
OMEGA TRC III Ice Point Reference (or stable ice bath)
•
Temperature Reference Probe Part Number: TRP-(*)
*Thermocouple Type J, K, T, E
3.2 Set-Up of Equipment
To prepare the ice bath: Refer to
Figure 3-1
a)
Fill a glass beaker with crushed ice made from distilled water.
b)
Fill the beaker with enough distilled water so that the ice just
becomes slush, but not enough to float the ice.
c)
Insert the reference thermocouple.
Figure 3-2
shows an alternate set-up. Here, a high precision thermocouple
calibrator, such as the Model CL511, replaces the DVM, ice bath, voltage
source, etc.
