    The self-contained unit offers excellent characteristics, together with full flexibility and ease of use. For the industrial user, the OD5 will provide facilities for diverse applications such as automatic processing, testing, etc., both on the shop floor or in the laboratory. In more scientific fields, the unit will find favour due to its versatility and adaptability to a wide range of transducers.

    2.6 MOUNTING The instrument is supplied with two (2) mounting bars that may be fitted to the base of the OD5 box. These bars in turn provide accessible fixing holes for mounting the instrument into a jig or fixture. 2.6.1 Fitting Mounting Bars To fit the optional mounting bars perform the following steps.

  • Page 11: Options

    OPTIONS 3.1 INTRODUCTION The OD5 has optional excitation frequencies of 2.5kHz and 5kHz which allow the device to operate with all standard Solartron Displacement and Gauging LVDT’s. Selection of the excitation frequency is by internal link settings. 3.2 5kHz OPERATION The 5kHz excitation frequency is required for operation with standard Solartron Gauging and Displacement LVDT’s calibrated at 5kHz.

  • Page 16: Gain Selection

    SETTING UP 5.1 GAIN SELECTION The OD5 is designed to operate with a transducer having a full scale output in the range 17-1,000mV/V. An internal link allows selection of Hi and Lo gain ranges (ref. section 3.6). Multi turn potentiometers allow fine adjustment of phase, zero and span settings.

  • Page 17: Calibration Using Phase Adjustment

    CALIBRATION 6.1 CALIBRATION WITH STANDARD SOLARTRON TRANSDUCERS With reference to Section 5 select the appropriate link 1 position. Unplug transducer and insert a link between pins 4 and 5 of connector 3. Adjust the zero control for zero output of the conditioner. Remove the link and replace the transducer.
  • Page 18 Plug connections apply to DIN standard 5-way 240° type. Where screen is used, connect to case of plug. Ensure that elsewhere the screen is isolated electrically. Cable colours are as fitted to Solartron transducers. Increase of element impedance marked P gives a positive going voltage output.
