ELT-400 5 Operation and use
5-11
Note: The measurement display will fluctuate whenever the setting is
changed. This fluctuation depends on the selected lower
frequency range limit and may continue for several seconds,
particularly if 1 Hz or 10 Hz is selected. Wait until the display has
settled before starting measurements.
5.3.6 Activating the MAX HOLD display function
The default setting updates the current measurement values in the display
continuously. Activating the MAX HOLD function causes the highest level
measured since activation of the MAX HOLD function to be displayed. This
considerably simplifies the measurement of fields that vary over time, and
particularly of pulsed fields.
If required, the highest field strength existing within the volume of a room
can also be displayed by moving the instrument around the room with the
MAX HOLD display function activated.

⇒
Press the MAX HOLD key until MAX appears in the display.
Deactivating the MAX HOLD function
