  • Page 2 The Model 9860 is a TEDS IEEE 1451.4 compliant, enhanced performance, microprocessor-based indicator capable of interfacing directly to a low level strain gage load cell transducer. The 9860 provides (3) user selectable calibration modes and (1) factory calibration mode. Consult Interface before accessing the Description factory calibration mode.
  • Page 3 To panel mount the 9860, perform the following steps. 1. Rotate the four pawl screws (outside screws in each corner) several turns counter-clockwise to retract the pawls. Make sure the pawls retract enough to clear the back of the mounting panel.

  • Page 5 The beauty of open collector outputs is, since these outputs are floating, they can be used with any voltage source up to 50 VDC. In this way you can match the output voltage level of the 9860 to any external equipment input be it 2.5 VDC or 48 VDC.

  • Page 7: Menu Function Definitions

    Menu Function Definitions Filter Value (FILtEr) (00 to 99) The 9860 uses a filter based on a digital averaging technique where N samples are arithmetically averaged. Subsequent averages subtract the oldest reading and add the newest reading. The number of readings is equal to the value of (FILtEr).

  • Page 12: Appendix A Understanding The 9860 Digital Filter Settings

    Understanding the 9860 Digital Filter Settings The 9860 digital filter is implemented as a cumulative moving average filter. It is used to filter the output of a 16-bit successive approximation analog-to-digital converter running at a rate of 250 conversions per second.

    50mV. To change the full scale range to 25mV, reference the instructions shown in Appendix E. Example: Calibrate the 9860 to read 00000 to 10.000 with an input of ZERO and XXmV/V full scale using a precision load cell simulator or known force (weight).

  • Page 14: Appendix C Calibrating The 9860 Using The Cal On2 Calibration Method

    In the CAL2 mode, the MAXIMUM FORCE or CAL value and the MAXIMUM OUTPUT in mV/V or SCALE values are entered. The 9860 uses these values to auto-calibrate the readout and analog outputs. ZERO or TARE may be initiated after the CAL2 calibration is completed.
