7.1 Temperature Measurement

The Raytech WR-Instruments are very accurate and precise test systems. To take full
advantage of this high accuracy, recording 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 Aluminium. These tables are used to automatically
calculate the conversion factor to a known reference temperature.
Temperature Coefficient Settings: see chapter 6.2.10 on page 41.

The system allows up to three (3) temperature probes to be used for the purpose of
recording temperatures. Optional Part Number: TP01, can be purchased for this purpose.
TP01 temperature probe is mounted to a flexible cable that plugs into the front 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 (TP03)
can be ordered to allow complete temperature measurements at three different reading
points.
The Instrument will automatically detect when a TP 01 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.
