2.16Setting Averaging
display rate average
The averaging allows for a stable display with varying flow amounts. Possible values, adjusted to the
requirements, are between 1 and 10000. In case of averaging the display of quick changes takes
place with a time delay.
Examples of reaction time for a change of 99.9% of the actual frequency jump:
o Averaging0 or 1: 0.02 s
o Averaging2: 0.04 s
o Averaging8: 0.16 s
o Averaging9: 1.3 s
o Averaging500: 75 s
o Averaging1000: 150 s
o Averaging10000: 1500 s
No filter is active for Averaging0 or1. In the case of Averaging2–8 a continuous average-value gen-
eration is carried out. A V
Z
1 filter is active at Averaging9–10000. In the process the old measured
value is weighted higher by the averaging value than the new measured value. Averaging of the dis-
play is also active on the Modbus.
2.17Setting Deactivate
alarm messages
Deactivate the display of alarm messages and group error message
Key combination + (Call up alarms) becomes ineffective.
2.18Setting Maximum
flow rate error message
Setting of the percentage via Q
nom
, for which the alarm Is exceeded is displayed. In this case Q
nom
is
always the flow rate at the highest still valid frequency of the linearization in Menu4 and Menu5.
2.19Setting Minimum
temperature volumeter
Set the smallest permissible operating temperature of the flowmeter. This temperature is limited
mainly by the selection of the pick up. A drop below it results in a corresponding error message.
2.20Setting Maximum
temperature volumeter
Set the highest permissible operating temperature of the flowmeter. This temperature is limited mainly
by the selection of the pick up. Exceeding results in a corresponding error message.
2.21Setting Reset to
factory setting
Reset of all settings to factory settings (delivery state)

3.03Setting Scale max.
analog output1
The scale of the analog output is used to set the maximum value. The maximum value is set slightly
higher than the highest possible occurring flow rate. If the value0 is entered here, Analog output 1 is
deactivated and 0V or 4mA respectively is output.
