Simulated operating mode
This function is intended primarily for checking the correct function of the system and is
selected and terminated at V8H0:
•
Enter 6 to simulate frequency, level, volume or current
•
Enter an operating mode to terminate simulation and resume normal
measurements.

V8H0
e.g. 6
Selects simulation mode channel 1, entries can be made at
fields V9H6
…
V9H9
or
e.g. 0
Selects two channel measurement and ends simulation

Four modes are possible:
•
Simulation of frequency, V9H6
•
Simulation of level, V9H7
•
Simulation of volume, V9H8
•
Simulation of current, V9H9.
When a value is entered at the appropriate matrix, the analog outputs are fed with the
appropriate current and voltage and the other 3 simulation values are recalculated.
Throughout the simulation the red alarm LED flashes to indicate that the instrument is no
longer measuring, the alarm relay does not, however, trip.
