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 instrumentsin a
4 to 20 milliamp DC loop. It can be used at anyaccess point in your loop. Source & Read 0.000 to 24.000 mA, Simulate
a 2 Wire Transmitter or use the PIECAL 434 tosimultaneously power your 2 Wire Transmitter and measure its output.
Easy to read
Turn on backlight & easily see the display indark areas of the plant.
Troubleshoot loop problems
Quickly diagnose ground fault and current leakagewith the
patented loop diagnostic technology (US Patent#7,248,058).
Source milliamps
Calibrate recorders, digital indicators, strokevalves or any
instruments that get their input from a 4to 20 mA loop. Easily set any value quickly to within 0.001 mA with theadjustable digital potentiometer “DIAL“or use preset 4.000 mA (0.00%) and20.000 mA (100.00%) EZ-CHECKsettings.
Automatic output stepping &ramping
Press & hold the dial to automatically stepfrom 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 thePIECAL 434 in place
of a 2 Wire transmitter. Uses any loop power from2 to 60 V DC.
Read loop current
Check controller outputs or measure the milliampsignal anywhere
in the loop. The PIECAL 434 measures 0.000 to24.000 mA (-25.00 to 125.00%) signals with greater accuracy than a typicalmultimeter.
Power & measure 2 wiretransmitters
The PIECAL 434 can simultaneously output 24V DCto power any and
all devices in a process loop using the internalbatteries and internal
Actual Size
switching power supply, while measuring theoutput of a 2 Wire Transmitter and any other loop devices. Powers
HART transmitters with built-in 250 ohmresistor simplifying hookups with HART communicators.
Read DC volts
The PIECAL 434 can measure from -60.00 to +60.00VDC 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 bymembers 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, tiltstand, backlit display with larger digits, rugged switches and a batterycompartment for fast battery
changes.
