TEMPERATURE MEASUREMENT
Raytech WR series Instruments are very accurate and precise test systems. To take full advantage of
this high accuracy, the recording of the temperature of the device under test is highly recommended.
This is due to the characteristics of the increase in resistance of a metallic object as its temperature
increases. Incorporated into the system are temperature compensation tables for Copper and
Aluminum. These tables are used to automatically calculate the conversion factor to a known reference
temperature.
Temperature Correction Settings: see page 49.
The system allows up to three (3) temperature probes to be used for the purpose of recording
temperatures. Optional Part Number: 2021N-26001, can be purchased for this purpose.
The temperature probe is mounted to a flexible cable that plugs into the rear panel of the WR-
instruments. This option enables the user to record the ambient temperature and/or the actual
temperature of the device under test. A set of
three (3) temperature probes can be ordered to
allow complete temperature measurements at
three different reading points.
The instrument will automatically detect when a
temperature probe is connected. The temperature
will be displayed on the instrument screen during
a test and will appear on the printed report. The
temperature, as well as the test results, can be
saved into memory.
As soon as a temperature probe is connected, the
value is displayed on the main screen and will
automatically be stored to the correspondent
resistance value.
