7.5.2 Frequency Bar-Graph Interpretation
The actual frequency depends on the power supply’s operating frequency. Use Table 7.6
to Table 7.8 below to interpret frequency bar graph readings.
NOTICE
If there is a test overload or an external memory reset signal is
received, then the 50% segment will be displayed and blinking.
