3 Features and Functions
Strain
This section describes how to configure the selected channel for strain measurements from the front panel. When a
force is applied to a body, the body deforms. The deformation per unit length is called strain (ε). Strain may be either
tensile (+) or compressive (-). The DAQ970A/DAQ973A supports two types of strain measurements which are Bridge
configuration and direct resistive method.
Once you have configured strain measurement function in all strain channels, press [Home] > Strain Offset to
measure or specify the unstrained offset that will be subtracted from strain measurements before the strain
conversion is performed.
Bridge configuration
Full and half bridge in bending arrangement
This section describes how to configure the selected channel for full and half bending bridge strain gage
measurements from the front panel.
1. Connect bridge configuration source to the module's screw terminals.
Full bending bridge:
Half bending bridge:
2. Press [Channel] > Measure, and select STRAIN from the selection menu.
