.
2. Clear the average value with using the keys
long, CLEAR

3. The averaging can be started with the key
START/STOP.
The arrow ´

indicated in the display.
4. The averaging can be stopped by operating the

Averaging over a Number of Single Measurements
For an averaging of isolated measurements at certain points or times (e.g. net
measurements) the averaging mode
´SinGL´
must be used. In this case
corresponding requirements must also be met:
Averaging mode of the selected channel ´

No cyclic measuring point scan (cycles stopped)
No continuous measuring point scan (no
C

1. Before each measurement the average value must be cleared in the
function AVERAGE VALUE by using the keys long,
CLEAR
.
ENTER
2. In the function MEAS. VALUE the single values are captured in the memory
for instant values by pressing the key
MEAS.VAL.
The arrow ´
HOLD
´ appears
in the display.
3. If the value is correct, it can be transferred into the memory for average
values by operating the key
START/STOP
. The arrow ´
HOLD
´ will then turn off.
4. If the value is not correct, it can be rejected by operating the key
MEAS.VAL.
once again, i.e. the arrow ´ HOLD ´ turns off and the current value is indicated.
5. To acquire more values, the steps 2 to 4 can be repeated.
6. To
indicate the average value the function AVERAGE VALUE ´
AV
´ must
be selected with using the key F1 .
7. With operating the key F1 once again, the count N of averaged values can
be obtained within the function ´
