9.4.5 Averaging over the Measuring Time
To determine the average value of all meas. values, that were acqired over the
conversion rate, over a defined period, the averaging mode
´CONT´
must be
set for the required measuring channel. Averaging can be carried out with or
without cycle. A measuring point scan will be performed in any case on start
and stop allowing to record the start and end values including the time of day.
A function channel
M(t)
is required for the recording of the average value M
(s. 10.3.9, 10.3.10).
Set the averaging mode:

9.4.6 Measurement Time
For the averaging over time (see above) and for many other measurement ex-
periments, in many cases, the actual measurement time, from start to stop, is
required. The function ´Measuring time´ has a resolution of 0.10s and is availa-
ble to allow a continuous monitoring of the measurement time without clearing
the real time. If the function ´Clear Meas. Values On Start of a Measurement´
is activated within the operating parameters (s. 10.5.8), the measurement time
will also be automatically cleared on each start.

Measuring time: 00:00:00.00
