12 VEGAMET 407 Z
Effects within the measuring range outside the measuring range
-10 % … 0 % ...............100 % … 110 % < -10 % or >110 %
0/4 mA...............20 mA 22 mA
0 V..................10 V 11 V
0 V....................5 V 5,5 V
Example to end simulation ...................................... • push MOD–button again
Effects - Cancel the simulated output values
- Transmits the true output values
Parameter adjustment
Integration time
Application
- Where the product surface is agitated the system
outputs may be stabilized by adjusting the inte-
gration time.
Important notes:
The integration time depends on the filling and
emptying period of the vessel, i.e. integration time
≤
filling / emptying time. Mis-adjustment of the
integration time may degrade output sensitivity.
Definitions
- range = 0 … 199 sec.
- (0 … 199 secs. corresponds to the definition in
sec.)
At 200 sec. effects a time period, the actual value
is approx. 45 minutes.
- settings > 200 sec. are automatically limited to
the max. value 200 sec.
Example
- integration time of e.g. 15 sec.
• select mode t in MODEFIELD
• program 15 sec. in PARAMETER FIELD
• then store with STO
Example ..............to activate the simulation ……… • select mode SIM in MODEFIELD
• activate the simulation with button MOD
• increase or reduce the output with button + or
button –
t
Simulation mode
In the simulation mode it is possible to test the
measuring system over the whole measuring range
independent of the process.
Button + increases and
button – reduces
all output values.
The longer the simulation button + and – are
pressed the greater the rate of change.
Integration time is ignored during the simulation
sequence.
