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.
Installation Guide
Installing the Interface Cable
IFC200 (sold separately) — Insert the device into a USB port. The drivers will install automatically.
Installing the Software
The Software can be downloaded from the MadgeTech website at madgetech.com
. Follow the instructions provided in the Installation Wizard. Compatible with
Standard Software version 2.03.06 or later and Secure
Software version 4.1.3.0 or later.
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
