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
potentiometerDIALor use preset 4.000 mA (0.00%) and20.000
mA (100.00%) EZ-CHECKsettings.
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.
