Wiring the Data Logger
Wiring Options
For 4-wire RTD probes, connect the four lead wires to your RTD logger as shown in the
figures below.
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 Ohm, 2 or 4 wire RTD probes are
recommended for the most accurate performance. Most 100 Ohm, 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 Ohm. (Note: Please contact the manufacturer of the RTD probe for questions on the resistance)
Device Maintenance
Battery Replacement
Materials:
3/32” HEX Driver (Allen Key)
Replacement Battery (U9VL-J)
- Remove the cover from the device by unscrewing the four screws.
- Remove the battery from its compartment and unsnap it from the connector.
- Snap the new battery into the terminals and verify it is secure.
- Replace the cover taking care not to pinch the wires. Screw the enclosure back together
securely.
Note: Be sure not to over tighten the screws or strip the threads.

Installation Guide
Installing the Interface cable
- IFC200
Insert the device into a USB port. The drivers will install automatically.
- IFC110
Plug the serial cable into the port and verify it is secure.
- USB-1 or USB-101
Install the USB drivers from the CD provided in the kit, then plug the USB cable into the
computer and the serial cable into the serial port.
Installing the software
Insert the Software CD in the CD-ROM Drive. If the autorun does not appear, locate the
drive on the computer and double click on Autorun.exe. Follow the instructions provided
in the Wizard.
Connecting the data logger
- Once the software is installed and running, plug the interface cable into the data logger.
- Click the Communication Menu, then Auto Configure Port.
- After a moment, a box will appear stating that a device has been found.
- Click OK. The Device Status box will appear. Click OK.
- At this point, communications have been configured for your logger. These settings can
be found under the Communication Menu.
Note: For additional installation instructions refer to your “Data Logger & Software Operating Manual”.
Device Operation
Starting the data logger
- Click Device Menu then Start Device.
- Choose the desired start method.
- Choose the start parameters by selecting a Reading Rate suitable for your application.
- Enter in any other desired parameters and click Start.
- A box will appear stating the data logger has been started. Click OK.
- Disconnect the data logger from the interface cable and place it in the environment to
measure.
Note: The device will stop recording data when the end of memory is reached or the device is stopped. At this point the device
cannot be restarted until it has been re-armed by the computer.
Downloading data from a data logger
- Connect the data logger to the interface cable.
- Click the Device Menu then Read Device Data. This will offload all recorded data onto
the PC.
