IMULATION
This function enables the user to test the settings of the outputs. The NIVOCAP can simulate the static or continuous change of level according to
the simulation cycle time, high level and low level set in
P85
,
P86
and
P87
. (The simulation levels must be within the programmed measuring
range set in
P04
and
P05
.)
After selecting simulation type in
P84
and setting simulation values Measurement Mode has to be re-entered. While the NIVOCAP is in simulation
mode the DIST, LEV or VOL symbol will be blinking. To quit Simulation Mode
P84= 0
should be set.

CCESS LOCK
P99: dcba Lock of programming by access lock
The purpose of this feature is to provide protection against accidental (or intentional) re-programming of parameters.
The Secret Code can be any value other than
0000
. Setting a Secret Code will automatically be activated when the NIVOCAP is returned to the
Measurement Mode. If the Secret Code is activated, the parameters can only be viewed, this is indicated by the a flashing colon “:” between the
parameter address and the parameter value.
In order to program the device locked by a secret code, first enter the Secret Code in
P99
. The Secret Code is re-activated each time the
NIVOCAP is returned to Measurement Mode.
To delete the Secret Code, enter the Secret Code in
P99
. After confirming it with
[E]
re-enter the parameter
P99
and enter
0000
.
