NOTE
Switching the range on each channel screen.
1. Switch to display the channel for which you wish
to change the setting.
2. Hold down the panel
RANGE
(+,-) key until the
desired setting range is displayed.
3. To set auto ranging, hold down the panel RANGE
(+) key or press both (+,-) keys simultaneously.
4. To cancel auto ranging, press either of the
+
and
-
keys.
Switching on the STATUS screen
1. Press the

(AUTO) ,
F1
( ↑ ; range up),
F2
( ↓ ; range down).
4. Press the
MEAS
key to return to the measurement
screen.
･
For channel combinations of 1P3W and above, the channels are forced to the
same range. In this case the range for the lowest-numbered channel is used
for all of the channels.
･
The auto ranging function switches up a range when a measurement value
exceeds 110% of measurement range (out-of-range) or when a waveform
peak exceeds six times the range value (peak over), and switches down a
range when the value is less than 30% of the nominal range. When
measuring a distorted waveform the range selection may not be stable. In
this case use manual range setting.
･ When the integration function time average has started, auto ranging is
disabled, and the range remains fixed from that point.
