Connections

Power

Attach power supply wiring to the module as shown below:
Connect to a 3 Volt power supply or batteries.
This module is not reverse polarity protected!
The maximum voltage is 3.6 V!
For battery information please refer to

Strain Sensor

Strain gauge connection is 4 wire as follows:
The resistance of the strain gauge can be between 85 and 5000 ohms. The T24-LT1 can support up to four 350
ohm strain gauges bridges attached in parallel (At the expense of reduced battery life).
The cable lengths between the T24-LT1 and the gauges should be kept below three metres and generally as short
as possible.
As the measurement is four wire then as the cable length increases the voltage drops in the cable will have more
of an effect on the factory mV/V calibration.
The strain gauge measurement is bi-directional, i.e. tension & compression.
