PIE Model 434 - High Accuracy Automated 4-20 mA Diagnostic Calibrator with atented Current Leakage Test. includes rubber boot, carrying case and FREE Traceable Certificate of Calibration
• Easy to use
With the PIECAL 434 you can check, calibrate
and measure all your current signal instruments
4 to 20 milliamp DC loop. It can be used at any
access point in your loop. Source & Read 0.000 to 24.000 mA, Simulate
a 2 Wire Transmitter or use the PIECAL 434 to
simultaneously power your 2 Wire Transmitter and measure its output.
• Easy to read
Turn on backlight & easily see the display in
dark areas of the plant.
• Troubleshoot loop problems
Quickly diagnose ground fault and current leakage
patented loop diagnostic technology (US Patent#
• Source milliamps
Calibrate recorders, digital indicators, stroke
valves or any
instruments that get their input from a 4
to 20 mA loop. Easily set any value quickly to within 0.001 mA with the
adjustable digital potentiometer "DIAL"
or use preset 4.000 mA (0.00%) and
20.000 mA (100.00%) EZ-CHECK™
• Automatic output stepping &
Press & hold the dial to automatically step
from 4 to 20 in 2, 3 or 5
steps or choose a continuous ramp.
• Calibrate using loop power
Check loop wiring and receivers by using the
PIECAL 434 in place
of a 2 Wire transmitter. Uses any loop power from
2 to 60 V DC.
• Read loop current
Check controller outputs or measure the milliamp
in the loop. The PIECAL 434 measures 0.000 to
24.000 mA (-25.00 to 125.00%) signals with greater accuracy than a typical
• Power & measure 2 wire
The PIECAL 434 can simultaneously output 24V DC
to power any and
all devices in a process loop using the internal
batteries and internal
switching power supply, while measuring the
output of a 2 Wire Transmitter and any other loop devices. Powers
HART™ transmitters with built-in 250 ohm
resistor simplifying hookups with HART communicators.
• Read DC volts
The PIECAL 434 can measure from -60.00 to +60.00
VDC with 0.01 Volt resolution. Use it to check loop power
supplies, I/V converters, 1 to 5 Volt signals,
and other voltages making it unnecessary to carry a multimeter.
• Evolutionary design
PIECAL Calibrators are designed and built by
members of the same team that designed and built the calibrators
manufactured by Fluke* under the Altek* label.
The PIECAL 434 improves upon other brands by including a rubber boot, tilt
stand, backlit display with larger digits, rugged switches and a battery
compartment for fast battery
