1.3.3.2 Low Voltage Test
To perform the low voltage test, follow these steps:
- 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.
Figure 1-12. Test Output—Low Voltage Test - Remove the voltmeter probe pins from the SM48D
adapter module.Note: Ensure special attention to avoid shorting pin 1 and 48.
- 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.
- To proceed to the next test, on the SS4 programmer, press the START push button.
