Digital Voltmeter
The digital voltmeter
may be used to measure the thermocouple voltage and determine the temperature
of the hot junction in the indium sample. This voltmeter is in parallel
with the computer data acquisition system. When used in conjunction with
the digital stop watch, the temperature-time curve for the indium can be obtained
during heating and cooling by reading the voltmeter and converting the
measured voltage into Celsius temperature.
Shorting Plug
A shorting banana plug is provided so that the zero
of the voltmeter can be checked or adjusted before data acquisition. Place
the plug across the voltmeter terminals and determine any offset error. |
