Martel Electronics LC-100 Data sheet
LC-100 Precision Loop Calibrator
Description
The LC-100 Precision Loop Calibrator provides
signifi cantly extended performance when compared
to any competitive calibrator. With an accuracy of
0.015% of reading, with 0.001 mA resolution, the LC100 has the highest accuracy in its class. Features such
as a “% Error” function, which eliminates manual error
calculation and allows the display of the actual versus
ideal error at any calibration point, put the LC-100 way
beyond similar instruments. The LC-100 can simulate,
power, and measure two-wire transmitters. With automatic Step and Ramp functions, the LC-100 enables
remote calibration of 4-20 mA devices.
Intuitive Interface
The LC-100 Loop Calibrator provides a highly intuitive user interface. A pair of cursor keys allows rapid
selection of the decade to be modifi ed, while a large
knob allows precise and rapid adjustment to any value
needed, with immediate feedback from the LCD display. A single MODE key cycles through and selects
the source, simulate, and measure modes.
Powerful Features
The LC-100 provides innovative, powerful features to
make your calibration job easier. A handful of clearly
marked keys provide access to the full functionality of
the unit. To enable remote calibration of devices and
processes, the LC-100 features automatic STEP and
RAMP output modes, which automate either a discrete
4-8-12-16-20-16-12-8-4 mA stair step output, or two
speeds of a linear 4-20-4 mA ramp output, respectively.
One or more simple pushes of the AUTO key (1) are
all that are needed to access this time-saving function.
To further aid remote calibration, the LC-100 features
a Minimum/Maximum value recall function. In the
measure mode, holding the AUTO(/MAX) key (1) provides a direct readout of the maximum value achieved,
while holding the 25%(/MIN) key (4) provides a direct
readout of the minimum value achieved. Holding
the % ERROR key (2) while turning the large knob
provides instant feedback of the difference between
the ideal and actual current values required for a given
device response. Instant verifi cation of whether the device is within its accuracy range is provided. No more
calculations are necessary!
