In order to start the operation function, press the INST/AVE key. In that case, an operation type is displayed at
the upper left part of display.
In Linear average, [LIN] is shown, in Exponential average, [EXP] is shown, and
in Maximum hold, [MAX] is shown. The average number is also displayed. If the INST/AVE key is pressed
again, it will change to the Instantaneous measurement and [INST] is shown.
If the START/STOP key is pressed where the operation type is LIN, EXP, or MAX, the average will start and
the counter of the average number will go up. If the START/STOP key is pressed again during the average
operation, the average will stop at the time. If the START/STOP key is pressed in the Instantaneous
measurement, the average will not start.

Fixing a FFT spectrum
In Linear average or Maximum hold, the operation stops when the average counter reaches to the average
number, and the FFT spectrum is fixed.
In Instantaneous measurement or Exponential average, the operation continues. When you read the frequency
or the amplitude of spectrum with cursor, press the PAUSE/CONT key. The measurement changes to the
paused state, and a measured FFT spectrum is fixed. To resume the measurement state, press the
PAUSE/CONT key one more time.
⑧
Zooming the X-axis and the Y-axis of the graph display
When the SCALE ON/OFF key is pressed, the display scaling function becomes operational. In this case, the
graph zoom symbol or the cursor move symbol is shown at the bottom left corner of the display.
The graph zoom symbol and the cursor move symbol can be changed by the SCALE EXPAND/MOVE key.
