Measurement
4-1.
Preparation
The tie-bar gage is mounted to a tie bar according to the installation manual.
Please mount the tie-bar gage and connect with the I/O terminal of CSA-593 correctly according to [3.
Wiring], and turn on the power.
4-2.
Execution of automatic ZERO
Please make sure to reset the output voltage by using A/Z (Automatic ZERO set) before the
measurement.
The lower or upper limit of output voltage in the product specification might be output in the initial
strain condition at the first mounting on tie bar because ZERO calibration at the shipment of tie-bar
gage is executed without mounting it on tie bar.
4-3.
Measurement
CSA-593 becomes possible to measure after the execution of ZERO set, because SPAN calibration of
CSA-593 is executed at the shipment. The relation between the input range and output voltage is shown
in the below table.
Input (x10
-6
strain) Output voltage (V)
+500 10
0 0
-500 -10
The output of tie-bar gage has the fluctuation element after turning on the power. Please use
CSA-593 after about 30 minutes has passed from turning on the power to work in stable condition.
