Program List and Explanations

3.3 Simulation
Select the alarm relay, relay 1 and 2, signal output 1 and 2, input,
magnetic valve 1 and 2 or stirrer with the up/down keys. Then press
<Enter> to change the setting or value. After confirming the setting
with the Enter key, the value is simulated by the relay/signal output.
At the absence of any key activities, the instrument will switch back
to normal mode after 20 min. If you quit the menu, all simulated val -
ues will be reset.
3.4 Set Time
Adjust date and time.
4 Operation
4.1 Grab Sample
4.1.5 Starts a grab sample measurement. Follow the instruction on the
screen. See Grab Sample Measurement, p. 47
4.2 Sensors
4.2.1 Filter Time Constant: Used to damp noisy signals. The higher the fil -
ter time constant, the slower the system reacts to changes of the
measured value.
Range: 5–300 Sec
4.2.2
Hold after Cal:
Delay permitting the instrument to stabilize again after
calibration. During calibration, verification or grab sample plus hold-
time, the signal outputs are frozen (held on last valid value), alarm
values, limits are not active.
Range: 0–6‘000 Sec
4.3 Relay Contacts
