Testing in Pass/Fail Mode or in Normal Mode
Pass/Fail mode: status is indicated directly (screen and LEDs). Status is
determined according to the current threshold set (see Selecting a Threshold
Set on page 14).
Normal mode: only the power levels are shown and LEDs are off.
Note:
If the result is greater than the Pass threshold, the word Fail and the LED
will flash. If the result is lower than the Fail threshold, the unit will only
display Fail and the LED will not flash.
At startup, the unit is in the same mode that was used during last test session.
