target". Switching signal can be inverted
with function no 8.
11 Q = trigger input mode:
1
With rising edge on Q
held until the next trigger occurs.
12 Q = enable input mode:
1
Used to switch laser beam on and off.
Laser beam is on when Q
= ­ U
Last measured value remains. When re­
activated, the response time is prolonged
according to the set mean value.
13 Switches off averaging:
The first measured value is taken into
account (page 35).
14 Switches on 4 ms averaging:
the first 10 meas. values are taken into
account (page 35).
15 Switches on 40 ms averaging:
all (max. 100) meas. values are taken into
account (page 35).
Set analogue output 0% (4 mA):
16
When S button is activated, the current
meas. value corresponds with 0% value of
the analogue output.
Set analogue output 100% (20 mA): When
17
S button is activated, the current meas.
value corresponds with 100% value of the
analogue output.
18 Q automatic zero mode:
1
For characteristic curve displacement. If
Q = +U
1
is set to the analogue value 0 % = 4 mA.
The incline of the characteristic curve is
maintained. If exceeded, the characteri­
stic curve ends at the start or end of the
measuring range.
19 Q automatic centre mode: displacement
1
of centre of characteristic curve. If Q
+U
B
the analogue value
50 % = 12 mA. The incline of the charac­
teristic curve is maintained. If exceeded,
the characteristic curve ends at the start
or end of the measuring range.
