7.3 Simulated operating mode
This function is intended primarily for checking the correct function of the system and is
selected and terminated at V8H0:
•
Enter 3 to simulate the input variable (pulse rate or frequency)
- display 0
…
9999, actual 0
…
99990
•
Enter 4 to simulate the normalised input variable (0
…
100)
•
Enter 0 to terminate simulation and resume normal measurements.
Start and stop simulation
Step Matrix Entry Significance
1 V8H0 e.g.3 Selects simulation of input variable
or
e.g. 0 Selects standard operation mode and ends simulation
2 - »E« Registers entry
When a value is entered at matrix position V9H6 or V9H7, the relay response can be
tested accordingly. Throughout the simulation the red alarm LED flashes to indicate that
the instrument is no longer measuring, the alarm relay does not, however, trip.
Countrate/frequency The countrate (or frequency) is entered in the same manner as it is displayed at V0H8,
i.e. as value/10, e.g.
•
120.1 = 1201 pulses/s, 1234 = 12340 pulses/s for DG 57
•
2.5 = 25 Hz, 0.9 = 9 Hz for DG 17/DG 27
Step Matrix Entry Significance
1 V9H6 e.g. 100 1000 pulse/sec for DG 57 or 1000 Hz for DG 17/27
2 - »E« Registers entry
Normalised countrate Any value between 0
…
100 can be entered
Step Matrix Entry Significance
1 V9H7 e.g. 10 Normalised countrate/frequency = 10
2 - »E« Registers entry
