Note: Internal acceptance limits for trigger low time are wider than those specified in Table 7-6, Table 7-7, and

Table 7-8, to accomodate +-20% oscillator drift.

1) UT = Programmed nominal SPC unit time

2) Trigger time in the sensor is fixed to the number of unit times specified in the “typ.” column, but the effective trigger time

varies due to the sensor’s clock variation
