7.1.2 Memory for Peak Values
From the acquired measured values of each measuring point the highest and
lowest value is determined and stored. For indicating the peak values the
function MAX. VALUE or MIN V. must be selected with the rotary switch and
the desired channel must be set by using the key
CH ▲
.
Function:
Peak values: MAX. VALUE
MIN. V.
Clear: Using the keys
ENTER
,
CLEAR
The peak values are cleared if a total clearing (see 7) or change of the range
(see 6.2) is carried out. If the cleared channel is the selected measuring
channel, the measured value will be indicated immediately after the clearing.
7.1.3 Averaging
The average value of the measured value is required for various applications:
e.g. - the average flow velocity in a ventilating channel
- smoothing of a largely varying measured value (wind, pressure etc.)
- hourly or daily average values of weather data (temp., wind etc.)
- as above, of consumption values (current, water, gas etc.)
The average value of a measured value, , results when a number of A
measured values A
i
are added together and then divided by the number N of
the measured values:
Average Value A =
i
(
Σ
A
i
)
/N
Indication and programming of an average value is performed by setting
the rotary switch to AVERAGE V. The type of averaging is determined
through the averaging mode. This function (
AM
) is activated by key
F
.
