7. CONNECTING A RTD
Use the correct 100
Ω
RTD (alpha =
0.003850) for your instrument. Using
an incorrect probe type will result in
erroneous readings. Insert the 3-pin
plug into the mating connector on the
top of the instrument.
If no probe is connected the display
will read “open”.
RTDs are sensitive at the tip or
sensing element. When taking
measurements, allow time for the
reading to stabilize. Multiplying the
time constant of the probe by 5 will
give you the approximate time
required.
