Calibrating BPM Microsystems Manual Programmers

Calibrating Programmers

Calibrating the BPM Microsystems programmer is not required. The hardware is designed to be very stable and does not need calibration. However, if the customer’s organization is ISO9000 certified or has some other military, medical, or government certification, it may require that all manufacturing equipment be certified each year. In this case, we provide this service to satisfy those requirements. (We just verify the calibration if there is no need to recalibrate the circuitry.)

BPM’s programmers are a self-calibrating unit. During operation, each pin driver is continuously monitored and calibrated by a special supervisory circuit. The self-diagnostic test will verify the correct operation of the pin drivers, power supply, CPU, memory, and communications. It is not necessary to recalibrate the unit in the field.

However, it is necessary to verify the accuracy of the self-diagnostic test to ensure that it will provide accurate results. The BPM Microsystems programmer uses an internal Digital Volt Meter to measure the voltage and/or current of 13 internal nodes and 48 analog pin drivers, allowing verification. Its accuracy may be verified with a bench DVM.


8th & 9th Gen Manual Programmers

The “VerifyCalibration” option (on the BPWin ‘Device‘ menu) can be executed to verify the accuracy of the internal DVM and time base using a bench DVM and oscilloscope. We recommend that the following procedure be performed every 12 months. This procedure may be performed in the field or at the factory for a small fee. If the unit fails the accuracy of the diagnostic tests, the unit must be returned to the factory for repair and failure analysis.

Equipment required:

  • Digital Volt Meter (must be rated at 0.1% precision)
  • Oscilloscope

Procedure for verifying the programmer’s calibration:

    1. Ensure that the 8th Gen [2800, 2800F, 2800F-MK2] or 9th Gen [1900, 2900] programmer is attached to the computer and is powered on. On an 8th Gen programmer, the “Yellow” (‘Active’) LED will be on and the “Green” (‘Pass’) LED will be flashing. [After BPWin initializes the unit, the “Yellow” (‘Active’) LED will be off and the “Green” (‘Pass’) LED will be on.] On a 9th Gen programmer, none of the internal LEDs will be on until BPWin initializes the unit.
    2. Install an FVE4SM32D socket card in socket location “A” (the left-most socket card location on the programming site).
    3. Open BPWIN. BPWin will detect and initialize the attached programmer. (Image above shows an initialized FP2800 )
    4. Select the “Programmer Diagnostics” routine by either:
      • Clicking the ‘paper‘ icon on the toolbar.
      • Clicking <Tools/Programmer Diagnostics>.
    5. When the ‘Self Test Configuration’ window appears, click <Cancel> to return to the BPWin main screen.
    6. Click the <Device> menu option at top of window (not the Device button) and select <VerifyCalibration> from the pulldown menu.
    7. The “Self Test Configuration” window will be displayed.
      Note: “Loop mode” is disabled (grayed-out).
      • Select the site(s) to be tested and click <OK>. [Note: If BPWin displays a “…missing socket module…” dialog box, click the ‘Do not show this message…’ box and then click <OK>.]
    8. The BPWin programmer diagnostic test will be run on the selected site.
      1. If the diagnostic test fails (does not pass), the Verify Calibration procedure will be skipped for the selected site. (Continue with step 11.)
      2. If the diagnostic test passes, the Verify Calibration procedure will run. (Continue with step 9.)
    9. Verify DC Calibration:
      The programmer will produce a voltage on pin 2 of the device socket.
      1. Connect the DVM to pins 1 (black lead) & 2 (red lead) and verify that the measured voltage is within the minimum and maximum values displayed on the screen.
      2. Disconnect the probes.
      3. Click <OK> to continue.
    10. Verify AC Calibration:
      The programmer will produce a pulse on pin 2 of the device socket.
      1. Connect the oscilloscope probe to pins 1 (ground lead) and 2 (probe tip) and verify that the positive pulse width is within the minimum and maximum values displayed on the screen.
      2. Disconnect the probes.
      3. Click <Close> to continue.
    11.  If multiple programming sites were selected in step 7, steps 8 through 10 will be repeated for the other programming site(s).

The programmer/programming site has to be repaired if (a) it fails the diagnostic test or (b) the Verify Calibration measurements are outside of the values displayed by BPWin. Please go to the RMA Procedurepage on our website for information on how to request a RMA number in order to send the programmer in for repair.

6th & 7th Gen Manual Programmers

An option in the self-diagnostic test may be executed to allow testing the accuracy of the internal DVM and time base using a bench DVM and oscilloscope or period counter. We recommend that the following procedure be performed every 12 months.  The procedure may be performed in the field or at the factory for a small fee. If the unit fails the accuracy or the self-diagnostic tests, it must be returned to the factory for repair and failure analysis.

Equipment required:

  • Digital Volt Meter (must be rated at 0.1% precision)
  • Oscilloscope

Procedures for verifying the accuracy of internal DVM:

  1. Secure the SM48D in place on the programmer (48 pin DIP socket module).
  2. Launch BPWin and go to Tools/Programmer Diagnostics
  3. Click Yes, when asked would you like to verify calibration with a voltmeter.
  4. Connect the BLACK lead of your DVM to pin 3 of the DIP Socket.
  5. Measure the voltage at pins 1 and 2 of DIP socket and check that they fall within the minimum and maximum levels displayed on the screen.
  6. Press any key to continue.

Procedures for verifying AC calibration:

At this point in the test, the programmer will produce a 900us pulse width on pin one of the DIP socket.

1. Use an oscilloscope or period counter to verify that the positive pulse on pin one is between 890us and 910 us.

This completes the traceability test. The programmer will then continue with the remaining self-diagnostic tests.  The self-diagnostic test should be performed on each programming socket module that will be used in addition to the SM48D socket module.

Please contact Customer Service if there are any questions concerning the calibration procedure.
