Your New PCL-130
Lighten your load…take the PCL-130 to ever y site. It’s
like bringing a cartload of test equipment from the shop to
the control room or the field. The PCL-130 sources and
reads DC like a milliamp or voltage calibrator, simulates and
measures T/Cs & R TDs lik e a temperature calibr ator, generates and counts frequency and Counts-Per-Minute like a
frequency calibrator and displays pressure like a precision
test gauge. Troubleshooting? It checks continuity with a
beeper and measures AC line voltage like a multimeter!
Calibrate Milliamp Inputs
Calibrate controllers, recorders and other devices in 4
to 20 or 0 to 20 mA loops. Source and read 0.00 to 24.00
mA, or Simulate a 2-Wire Transmitter.Use the optional AC
adaptor for continuous operation.Display to 0.01 mA , 0.1
% of 4 to 20 and 0.1 % DP Flow.
Calibrate 2-Wire Transmitters
Easily calibrate 2-Wire Pressure and Electronic
Transmitters by connecting the PCL-130 to both the input
and output of the transmitter. The PCL-130 will simultaneously indicate the input and output of the transmitter on the
graphical display.
Calibrate Pressure Systems
Read pressure with extreme accuracy using an external
PM130 pressure module in a companion PCL130-MH
module holder. Attach the module directly to the pressure
connection for the best accuracy or with optional tubing for
tight spots. Display to five digits within 0.025% of reading
in up to 20 engineering units including psi, pa, Kpa, Mpa,
BAR, mBar, Atm, Kgf plus torr, inches and mm of mercury

CHECK 1-5 VOLT INPUTS
WITHOUT DISCONNECTING WIRES
Most 1-5 Volt receivers in 4-20mA loops have a 250 Ohm resis-
tor across the input of the receiver.This resistor may be mounted
internally or externally. PCL-130 is connected directly across the
input of the 1-5 Volt receiver without disconnecting any field wiring.
This saves a great deal of time when a large number of voltage
receivers, such as chart recorders or computer systems, require
calibration.
Make certain that changing the signal input will not disturb the
process or cause unexpected alarms when checking on-line
instruments. It is impor tant to remember the 130 drives only the
device to which it is connected. It has no effect on other devices in
the 4 to 20 mA loop.PCL-130 will clamp the selected value in the
mV and V Ranges to the maximum source or sink current of >16
mA.
1) Turn the Selector Knob to V
2) Press the DISPLAY/SOURCE/READ push-button until SOURCE
and V or mV appear on the display
3) Press the TYPE/ENG UNITS push-button once to switch
between V and mV on the display
4) Connect the red SOURCE lead of the calibrator to the plus (+)
input of the device and the black SOURCE lead to the minus (-).
Any associated 250 Ohm resistor must not be disconnected.
