1.1.3.
4-Wires
Resistance Meter allows the measurement at four wires of the load resistance, which allows to
take the measurement on loads far from the instrument avoiding that itself results faulty.
This type of measure necessitates only three ulterior connections (SENSE contact-plugs) of small
section and, in the case of wrong connection, a LED at the base of the display visualizes the
presence of it.
1.1.4.
Delay / Hold /Range function
With the
DELAY
commutator it is possible to choose the time of response of the RM, adapting it to
the various demands, decreasing the disturbances to the measure caused from the pulsating loads
like for example the motors for compressor.
The
HOLD
function, insertable with proper commutator, allows to memorize the last measure
taken.
Acting on the commutator
OHM RANGE
it is possible to choose among four values of span: 2, 20,
200, 2000 ohm (on request extended range 20÷20000 ohm).
1.1.5.
Remote Control
A rear connector allows the interface of the instrument with cards of I/O. Both an analog signal
proportional to the read value and the suitable signals to characterize the scale to which it refers
are present on that connector. It should be remarked that the analog output is completely
insulated from the circuit of measure through optical digital coupling. From the outside it is
possible to control, through this connector, both the choice of the phase to measure (UV-UW) and
the modality of measure (OHM-VOLT).
