Measurement
8. Press the Start/Stop key to start the measurement.
During measurement, the symbol flashes and the elapsed
measurement time is displayed every one second.
When the measurement time set in step 4 has elapsed, the measurement
terminates automatically. When wishing to terminate the measurement
earlier, press the Start/Stop key.
If no display (arbitrary measurement time) was selected, the Start/Stop
key must be used to conclude the measurement.
If an under-range condition or over-range condition occurs at least
once during measurement, the "
O v
" (Over) or "
U n
" (Under) indicator
appears, to show that the processing data contain over-range or under-
range data.

the A/C/FLAT key and Level keys are inopera-
tive. Only the following four keys can be used:
Start/Stop, Pause/Cont, Mode, Light. All other
settings must be made before starting the mea-
surement.
