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 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. Uses any loop power from 2 to 100 V 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 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 by members of the same team that designed and built the calibrators
manufactured by Fluke* under the Altek* label. The PIECAL 334Plus improves upon other brands by including a
rubber boot, tilt stand, backlit display with larger digits, rugged switches and a battery compartment for fast battery
changes.
