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.
