Before using the logger, the internal jumpers positioning must be set
according to the input type used.
The factory setting of these jumpers is for measurement of Pt100 /
Thermocouple / 0-50mV signals.
Figures below show some positioning for possible input types.

EXTERNAL BATTERY SWITCH
The example in (Fig. 11) below shows the usage of the external
battery switch for commanding the power supply of external devices.
Channel 1 is configured to 4-20mA input signal. A battery is used to
provide power to the 4-20 mA loop. The battery switch "turns on" the
power to the loop a moment (defined in the configuration) before the
measurement is taken, enabling the transmitter (pressure,
temperature, etc) to start up and stabilize the output.

DIGITAL INPUT (DI)
The Digital Input that can be used to guide the logger readings is
available in terminals 7 (-) and 10 (+) of CN2.

INSTALLATION RECOMMENDATIONS

Signal wires should be installed in grounded conduits and away from
power or contactor wires.
Instruments must be powered only by an exclusive power supply.
System failure should always be taken into account when designing
a control panel to avoid irreversible damage to equipment or people.
Installing RC filters (47 R and 100 nF, serial) is strongly recommended
at contactor coils or any other inductors.
OFFLOADING AND DATA VISUALIZATION
The transference of data to a PC is accomplished by using the
LogChart II software. Data can be collected anytime and saved in
files for future analysis (menu "File Save" or "File Save as"). Help can
be accessed from the LogChart-II software when necessary.
Offloading data: data offload is accomplished by clicking on the
button:
Or using the LogChart-II menu. During data transference, a status
bar indicates remaining data to be transferred. Data offloading time is
proportional to the number of readings logged. At the end of data
transference, the Graph window is displayed.
Graph window
The Graph is a convenient tool for analysis. It enables the logger
acquisitions to be read in the form of a "values x time" graph. As one
moves the mouse in the chart area, the time and the value of the
records of each channel are shown in the field located in the bottom
of the window.
Zooming in and out are implemented. It is possible to select an area
by clicking and dragging the mouse, thus creating a zoom region,
starting at the upper left position of the region of interest.
