CALOG - LC II
Hand-Held Loadcell Display/Tester/Calibrator
The
- LC II is a portable, multifunction, precision instrument for straingauge
loadcell system testing and calibration. This
model now includes the powerful ARM
processor, a display function (ideal for
portable scales or field readings), an SD card
for datalogging, a USB port for connection to
a computer for certificates or spreadsheets
and longer lasting Lithium-Ion battery pack.
Supplied complete with carrying case, charger
and leads.
DISPLAY: mass, force, strain or torque from
loadcells. Set mV/V, range, decimal points
and units. Zero and span trim available.
Selections for tare, peak hold and auto zero
maintenance. Can be used for one 350 Ohm
or three 1000 Ohm loadcells.
TEST LOADCELL: connect the loadcell leads
to spring terminals and select test to get a
readout of 4 or 6-wire, zero balance, input and
output resistance and bridge balance. This is
an ideal, time saving way to field test individual
loadcells in position.
INSULATION TEST: connect leads to screen,
housing and gauge to get a 50V insulation test
between each in megohms. This test will show
up water ingress that can cause loadcell
measurement errors.
MEASURE: high accuracy measurement of millivolts with a secondary display of excitation voltage and milliamps for
loadcell systems. Use this function to compare the actual loadcell readings with amplifier outputs or display readings
for fault finding.
SOURCE: high accuracy millivolt injection with display of excitation voltage and mA output for workshop or field
calibration of amplifiers and indicators.
SIMULATE: for sourcing milliamps into remote displays or SCADA systems. The
or mass equivalent.
- LC II display can be in mA
SETTINGS: allows you to set up the unit for power savings, contrast, language options and technical access.
HELP: gives you connection diagrams for each application, like having a built-in manual.

CALOG Calibrators
The
range of process instrumentation calibrators are designed for servicing, repairs in the workshop and the
plant environment. They are tough, sophisticated precision instruments that are portable, compact and user-friendly.
Robust enough to withstand the rigors of most industrial environments, they are powered by long-life lithium Ion
batteries and incorporate a clear, back-lit LCD graphic display.
For quick source value set-up, the
