Bridge101A
Product Notes
The Bridge101A data logger is designed to interface with and measure strain gauges and load
cells. The device provides an excitation voltage of 2.5V’s and is available in the following
millivolt input ranges: ±30mV, ±150mV, ±1000mV.
LEDs
- Green LED: every 10 seconds to indicate logging and 15 seconds to indicate delay
start mode.
- Red LED: every 10 seconds to indicate low battery and/or memory and 1 seconds to
indicate an alarm condition.
Installation Guide
Installing the Interface cable
- IFC200
Insert the device into a USB port. The drivers will install automatically.
Installing the software
Insert the Software USB Stick in an open USB port. 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.
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
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: Small Phillips Head Screwdriver and a Replacement Battery (LTC-7PN)
