10.4.6 Measurement Time, Measuring duration, Timer
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 avail-
able 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. 11.5.8), the measurement time
will also be automatically cleared on each start.
Function measuring time:
Measuring time: 00:00:00.00
Clearing the measuring time by using:
<CLEAR>
Measuring duration
If you want to stop a measuring operation or an averaging process (see above)
after a certain length of time, you can program the measuring duration in the
menu
Times - Cycles
or in a user menu; (this function is displayed in the sta-
tus bar with ´
©l
´). (see 10.1.4)
Measuring duration function
Measuring duration 00:00:00
Use a programmed measuring duration when recording to memory;
this ensures that recording does not abort prematurely.
Timer as function channel
Measuring times can be output and saved by means of the function channel
Time
; the format is “sssss” or “ssss.s”. (see 10.3.9) The resolution can be
raised to 0.1 seconds by programming the exponent to -1. At a count of 60000
the timer is reset and starts again at 0. All the normal start / stop functions can
be used; in addition, the start, stop, output, and zero-setting of the timer can
also be triggered by actions in the event of limit values being exceeded.
10.4.7 Averaging over the Cycle
The averaging mode ´
CYCL
´ must be used if average values have to be ac-
quired in cyclic periods over these periods. This ensures, that the average
value is cleared after each cycle, but appears in the display during the next cy-
cle.
