To
adjust the gain
, move the measuring tube to the end of the (nominal)
measuring range and use the gain potentiometer P
E
to set the output signal
to the desired value (usually
10 V
or
20 mA
).
5.4 Basic configuration of measuring amplifier
If the adjustment range of a trimming potentiometer is not sufficient for the
required adjustment, you must change the basic configuration. To change the
basic configuration, solder in fixed resistors and/or capacitors.
Hazardous voltages inside
the measuring amplifier with 230 V supply
voltage (type 46.31.2x).
Touching live parts can result in death, serious injury or considerable
property damage.
•
Soldering work must only be done by qualified skilled persons and only
in accordance with these instructions.
•
Before opening the field enclosure, check all conductors. They must be
de-energized.
•
De-energize the device first, before doing any assembly and soldering
work.
If you cannot do the basic configuration on site, you can also
have the conversion done at the factory. In this case, send the
measuring amplifier freight prepaid along with your requirements
(measurement range, desired output range) to MESSOTRON. If
you are using a third-party sensor, we also need the
displacement sensor or at least its specifications.
