• EASY TO USE

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 the backlight to easily read the display in

dark areas of the plant.

• TROUBLESHOOT LOOP PROBLEMS

Quickly diagnose ground fault and current

leakage with the patented loop diagnostic

technology (US Patent# 7,248,058).

• 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™ settings.

• AUTOMATIC OUTPUT STEPPING & RAMPING

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 334Plus in place of a 2 Wire transmitter.

The PIECAL 334Plus uses any loop power from

2 to 100V DC.

• READ LOOP CURRENT

Check controller outputs or measure the milliamp

signal anywhere in the loop. The PIECAL 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 334Plus 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 334Plus can measure from -99.99 to +99.99 VDC with 10mV resolution. Use it to

check loop power supplies, I/V converters, 1 to 5 Volt signals, and other voltages making it

unnecessary to carry an additional multimeter.
