Automated 4-20 mA Diagnostic Calibrator

PIE Model 434 – High Accuracy Automated 4-20 mA Diagnostic Calibrator with atented Current Leakage Test. includes rubber boot, carrying case andFREE Traceable Certificate of Calibration

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.

Turn on backlight & easily see the display indark areas of the plant.

Quickly diagnose ground fault and current leakagewith the

patented loop diagnostic technology (US Patent7,248,058).

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-CHECK™settings.

Press & hold the dial to automatically stepfrom 4 to 20 in 2, 3 or 5

steps or choose a continuous ramp.

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.

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.

The PIECAL 434 can simultaneously output 24V DCto power any and

all devices in a process loop using the internalbatteries and internal

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.

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.

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.
