Use of an anti-static wrist band or other grounding procedures are recommended.

  • Page 9: Glossary Of Terms

    1.3 Glossary of Terms Absolute displays the check size as the actual part size. An A/E (Air to Electric) transducer converts changes in pneumatic pressure into an electrical signal. +APPROACH (or -APPROACH) are optional user defined programmable values approaching the max and min part limits. AVG (Average) is a function that returns the average check reading.
  • Page 10 An LVDT (Linear Variable Differential Transformer) is an electromechanical transducer that converts the linear motion of its contact tip to an AC voltage which can be interpreted by a readout device. Magnification is the enlargement of an input signal to a usable value that can be interpreted by the readout device.
  • Page 11 A Signal Conditioner is a circuit board that modulates and amplifies the LVDT or A/E signal used by the readout device. A Single Check Program allows the user to program the Accusetter II for one dimensional check. In Setup Mode the user can program the required variables for the par checks and transducers.

    3.4 Input Setup Setting A/E Mag and Zero for Air Gage NOTE: Inputs MUST be setup from the Calibration, Inputs menu not in RUN mode. In Run mode the master corrections are applied. In Calibration mode the raw input readings are displayed. If the gage tooling is an airplug or air ring using an (1) channel or (2) channel A/E module use the following procedure to set zero and magnification for each input(s) using a set of max and min masters.
  • Page 73 For example, for the above example after turning the mag knob the displayed reading may be (+.0005) + (.0012) = +.0017 or it could read (+.0005) - (.0012) = -.0007. This depends on the polarity of the check. 10) After adjusting the mag knob, turn the zero knob in the same direction as the mag knob to adjust the displayed reading to equal the deviation of the MIN master value on the calibration sheet.

    4.4 Communications RS232 Communications Figure 4.7- RS-232C The Accusetter II's RS232C serial port provides a path to communicate to external devices such as a Data Collector, Personal Computer (PC), or serial printer. The RS232C connector is a standard 9-pin “D” style and is located on the back of the Accusetter II. The following pins on the connector are utilized for communications: Accusetter II Cable...
  • Page 98 Offloading Data Current measurement results can be offload through the RS232C connection. The offloaded data consist of the check name, measured numeric value, scale (inch or metric), status (good, over or under), and class. There are three ways of initiating data offload from the Accusetter II. They are as follows: The operator can initiate offload by pressing the “ENTER”...

This is performed by *pressing the enter button twice while the Accu-Setter is in the RUN mode. For the data collector to automatically solicit data, an “EEH”...
  • Page 100 RS-232 Personal Computer The PC Data protocol allows someone with knowledge of RS-232 communications to write a software program to communicate to the Accu-Setter. The PC Data protocol consists of two main categories: 1. Uploading measurement data 2. Downloading command codes The PC is considered the Master in the system.
  • Page 101 (RS-232 Personal Computer, continued) The PC can request two types of numeric measurement data from the AccuSetter: 1. Current Data — Current measurement readings being displayed on the Accu-Setter. 2. Saved Data — Measurement readings stored in the Accu-Setter’s memory. The Accu- Setter can store the active reading.
  • Page 102 (RS-232 Personal Computer, continued) If the Accu-Setter is executing the MPF FXT program, then the response packet will just contain the displayed fixture. The response packet will contain five fields for each feature being measured. Each field will be separated by a semicolon (;) delimiter. If their is no data for a particular field, the delimiter will still be included in the response packet.
  • Page 103 (RS-232 Personal Computer, continued) The PC can also simulate the push-button panel on the Accu-Setter through command codes. Command codes consist of a single byte which is not station dependent. The Accu-Setter does not transmit a response packet on receipt of a command code. Command codes transmitted from the PC will affect all of the Accu-Setters connected to the daisy chain serial link.
  • Page 104 RS-232 Upload/Download The format for a parameter upload response will consist of 192 bytes plus the bcc and eot characters: <192 bytes><bcc><eot> (Mark Parity) The bcc is calculated by performing the XOR function on the 192 bytes of packet data. A complete parameter upload will consist of the PC requesting four parameter packets (30h - 33h) from the Accu-Setter.

Solution: Readjust air inputs or position of LVDT gage head. MAX = MIN Cause: The gaged value of MAX equaled the gaged value of the MIN during the mastering routine.
