RTDTemp101A
PRODUCT USER GUIDE
Product Overview
Don’t be fooled by the small size, the RTDTemp101A
temperature data logger offers a wealth of features with
a compact form factor about the size of a matchbox.
When used with an external RTD probe, this data logger
measures temperatures from -200 °C to 850 °C (-328 °F to
+1562 °F).
The low power design of this data logger provides a
battery life of up to 10 years but still delivers ultra-fast
download speeds. The RTDTemp101A can store over
a million readings and offers a software configurable
memory wrap option. In addition to having a pushbutton
start stop, the device also can be programmed to a delay
start up to 18 months in advance.

Wiring the Data Logger
Wiring Options
For 4-wire RTD probes, connect the four lead wires to your RTD logger as shown in
the figure.
For 3-wire RTD probes, short inputs 3 and 4 together, then connect the lead wires
to inputs 1, 2 and 3.
For 2-wire RTD probes, short inputs 3 and 4 together and inputs 1 and 2 together,
then connect the RTD lead wires to inputs 2 and 3.
Warning:
Note the polarity instructions. Do not attach wires to the wrong terminals.
100 Ω, 2 or 4 wire RTD probes are recommended for the most accurate
performance. Most 100 Ω, 3 wire RTD probes will work, but MadgeTech cannot
guarantee the accuracy. To determine whether or not the 3-wire RTD probe will
work, the resistance between the two same colored wires should be less than 1 Ω.
Note:
Please contact the manufacturer of the RTD probe for questions on the resistance
