    The WDS-180A is a compact and lightweight digital indicator specified for strain gage transducers. The WDS-180A is an indicator that not only displays physical quantity of the transducer but measures the initial value of the transducer in [μm/m] or [mV/V] and conducts automatic sensitivity registration when the Transducer Electronic Data Sheet (hereinafter referred to as the TEDS)-compatible transducer is connected.

    7. SETTING OPERATION AND FUNCTION The WDS-180A is provided with ‘STRAIN Mode (STRAIN)’ that measures the actual output of the strain gage transducer and ‘MEAS Mode (MEAS)’ that displays physical quantity by multiplying coefficient. 7-1 SWITCHING STRAIN UNIT (F-1) • The WDS-180A displays the output of the strain gage transducer in [μm/m] or [mV/V].

  • Page 10: Meas Mode

    7-3 MEAS MODE Converts the output of the strain gage transducer to the physical quantity and displays the converted data. 7-3-1 Calibration Registers the conversion coefficient for displaying the transducer output in physical quantity. It is essential to conduct either the ‘Load CAL (Actual Load Calibration)’ or ‘Sensitivity CAL (Sensitivity Registration Calibration).’...

  • Page 12: Teds Function

    The TEDS loading operation is set with the ‘F-7’ setting. When the ‘Conducting ZERO after the TEDS operation’ is set to ‘0: Conduct’, after the Sensitivity CAL (Sensitivity registration calibration), the WDS-180A conducts ZERO to display ‘0.’ Then, the measurement can be started immediately.
