4 CABA LOCAL
4.13 Transducers menu
All transducers that you use for circuit breaker testing
are administrated and calibrated via this menu. Once
the transducers are defined it is just to pick them from
the list when testing.
Define new transducer
1]
Press the “DEFINE NEW TRANSDUCER” but-
ton and the following screen appears.
In CABA Local transducers are sorted in groups depending
on the transducer input type.
2]
Select the desired transducer type.
Defining motion transducer
1]
Press the “MOTION” button.
2]
Select the appropriate transducer output
type by pressing the”Transducer type” but-
ton repeatedly. There are three different
transducer output types available:
▪
“resistive” transducer output is a voltage that is
depending on the position of the transducer.
▪
“Digital” transducer outputs are pulses depending on the
position of the transducer.
▪
“4 – 20 mA” transducer output is a current depending on
the position of the transducer.
Calibrating resistive transducers
The calibration can be done in three different ways:
A]
Manual. Enter all values (pairs of position &
voltage reading) manually.
B]
Using the instrument readings as reference.
Enter position value manually while using
automatic the instrument voltage reading.
C]
Using digital transducer as reference. Using
automatic position reading from a digital
transducer and automatic voltage reading
from the instrument.
Note The system assumes that you use a voltage
reference of 4095 mV applied across the
transducer to be calibrated. If you connect
any other reference you have to multiply each
voltage reading with 4095 / (applied ref. volt
(mV)).
A. Manually calibrating a resistive
transducer
1]
Press the “Calibrate” button. The following
question appears.
