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 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)
Installation Guide
Installing the Interface cable
- IFC200
Insert the device into a USB port. The drivers will install automatically.
- 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
The Software can be downloaded from the MadgeTech website at the following link: www.
madgetech.com/software-download. Follow the instructions provided in the Installation
Wizard.
Device Operation
Connecting and starting the data logger
- Once the software is installed and running, plug the interface cable into the data logger.
- Connect the USB end of the interface cable into an open USB port on the computer.
- The device will appear in the Connected Devices list, highlight the desired data logger.
- For most applications, select “Custom Start” from the menu bar and choose the desired
start method, reading rate and other parameters appropriate for the data logging
application and click “Start”. (“Quick Start” applies the most recent custom start options,
“Batch Start” is used for managing multiple loggers at once, “Real Time Start” stores the
QuadRTD and OctRTD Product User Guide
dataset as it records while connected to the logger.)
- The status of the device will change to “Running”, “Waiting to Start” or “Waiting to
Manual Start”, depending upon your start method.
- 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 logger to the interface cable.
- Highlight the data logger in the Connected Devices list. Click “Stop” on the menu bar.
- Once the data logger is stopped, with the logger highlighted, click “Download”. You will
be prompted to name your report.
- Downloading will offload and save all the recorded data to the PC.
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.
Recalibration
The QuadRTD or OctRTD standard calibration is at two points, 50 Ω
and 15
0 Ω
.
