With an accuracy of 0.015% of
reading, 0.001 mA resolution,
and 1 microamp step 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.
