1.3.3.2 Low Voltage Test

To perform the low voltage test, follow these steps:

  1. Measure the voltage of pin 1, see the following figure. Voltage reading must be within the specified range. Otherwise, the programmer is out of calibration and needs servicing.
    Figure 1-11. Measure the Voltage of Pin 1

    The following figure shows the allowable range of the low voltage test.

  2. Remove the voltmeter probe pins from the SM48D adapter module.
    Note: Ensure special attention to avoid shorting pin 1 and 48.
  3. Connect the scope probe to pin 1 and ground to pin 48.
    Note:
    • Ensure to give special attention to avoid shorting pin 1 and 48.
    • Do not connect the ground pin of the scope to pin 1 of the SM48D adapter module.
  4. To proceed to the next test, on the SS4 programmer, press the START push button.
