With an accuracy of 0.015% of
reading and 0.001 mA resolution,
the PCL120 has the highest
precision in its class. Other features
that make the PCL120 stand out
include a “% error” function, which
eliminates manual error calculation
and allows the display of actual
versus ideal error at any calibration
point. The PCL120 can simulate,
power, and measure 2-wire
transmitters. Its’ automatic step and
ramp functions enable remote
calibration of 4 to 20 mA devices.
The PCL120 has many innovative,
powerful features that make
calibration easy. A few clearly
marked keys give the user access
to the full functionality of the unit.
The STEP and RAMP output
modes automate either a
discrete
4-8-12-16-20-16-12-8-4 mA
stair
step output or 2 speeds of a linear
4-20-4 mA ramp output. Pressing
the AUTO key (1) activates this
time-saving function. To further
aid remote calibration, the PCL120
features a minimum/maximum
value recall function. In the
measure mode, holding the
AUTO(/MAX) key (1) gives a
direct readout of the maximum
value, while holding the 25%(/MIN)
key (4) gives a direct readout of
the minimum value. Holding the %
ERROR key (2) while turning the
large knob provides instant
feedback on the difference between
the ideal and actual current values
required for
a given device response. This tells
the user whether the device is
within its accuracy range. No further
calculations are necessary. A LOOP
POWER key (3) provides instant
24 Vdc loop power output. The
25% (4) key provides instant
outputs of 4, 8, 12, 16, and 20 mA
loop current, with increments
occurring each time the key is
pushed.
