Bridge101A

Product Notes

The Bridge101A Data Logger measures and records voltage, typically used in conjunction

with strain gauges, load cells or other low-level DC voltage sources. This device is designed to

accurately measure and record the output of the gauge to determine parameter levels such as

stress, torque, strain, and pressure on a structure or item over a period of time.

Available in three different measurement ranges (±30 mV, ±160 mV or ±1200 mV), the

Bridge101A offers a reading rate of up to 4 Hz with memory capacity of 1,000,000 readings

(memory wrap optional). The device can be conﬁgured to start at a speciﬁed date and time

up to 24 months in advance and the pushbutton start/stop feature allows the user to initiate

or cease logging data in the ﬁeld if desired.

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.

Product Information Card

- 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)

- Puncture the center of the back label with the screw driver and unscrew the enclosure.

- Remove the battery by pulling it perpendicular to the circuit board.

- Insert the new battery into the terminals and verify it is secure.

- Screw the enclosure back together securely.

Recalibration

Bridge101A standard calibration values:

Logger Voltage 30 mV 150 mV 1000 mV

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.

Strain (V) 0 V and 22.5-25 mV 0 V and 90-100 mV 0 V and 900-1000 mV
