Automated Milliamp Calibrator

PIE Model 334Plus – Automated Milliamp Calibrator with Patented Current Leakage Test. Includes rubber boot, carrying case and FREE NIST Traceable Certificate of Calibration

• With the PIECAL 334Plus you can check,

• calibrate and measure all your current signal

• instruments in a 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

• 334Plus 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 loopproblems

Quickly diagnoseground fault and current leakage with the

patented loopdiagnostic technology (US Patent 7,248,058).

• Source milliamps

Calibrate recorders,digital indicators, stroke valves or any

instruments that gettheir input from a 4 to 20 mA loop. Easily set

any value quickly towithin 0.001 mA with the adjustable digital

potentiometer“DIAL”or use preset 4.000 mA (0.00%) and20.000

mA (100.00%) EZ-CHECK™settings.

• Automatic outputstepping & ramping

Press & hold thedial to automatically step from 4 to 20 in 2, 3 or 5

steps or choose acontinuous ramp.

• Calibrate usingloop power

Check loop wiring andreceivers by using the PIECAL 334Plus in

place of a 2 Wiretransmitter. Uses any loop power from 2 to 100 V DC.

• Read loop current

Check controlleroutputs or measure the milliamp signal anywhere

in the loop. ThePIECAL 334Plus measures 0.000 to 52.000 mA

(-25.00 to 300.00%)signals with greater accuracy than a typical

multimeter.

• Power &measure 2 wire transmitters

The PIECAL 334Pluscan simultaneously output 24V DC to power any and all devices in a process loopusing

the internalbatteries and internal switching power supply, while measuring the output of a 2Wire Transmitter and

any other loopdevices. Powers HART™ transmitters with built-in 250 ohm resistor simplifyinghookups with HART

communicators.

• Read DC volts

The PIECAL 334Pluscan measure from -99.99 to +99.99 VDC with 0.01 Volt resolution. Use it to checkloop power

supplies, I/Vconverters, 1 to 5 Volt signals, and other voltages making it unnecessary tocarry a multimeter.

• Evolutionarydesign

PIECAL Calibratorsare designed and built by members of the same team that designed and built thecalibrators

manufactured byFluke* under the Altek* label. The PIECAL 334Plus improves upon other brands byincluding a

rubber boot, tiltstand, backlit display with larger digits, rugged switches and a batterycompartment for fast battery

changes.
