This is a dynamic strainmeter that uses direct current as the bridge power supply.
The bridge power supply can be selected from constant voltage or constant current type.
In the constant-current type, there is no sensitivity reduction due to the resistance of the connecting cable between the strain gage transducer and the bridge box.
The instrument can be built into a dedicated case or rack for multi-channel configuration.
