Piecal 434 milliAmp Loop Diagnostic Calibrator, find hidden loop problems

Description

PIECAL High Accuracy Milliamp Loop Diagnostic Calibrator

With the PIECAL 434 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 434 to simultaneously power your 2 Wire Transmitter and measure its output.

Features

• Simulate a 2 Wire Transmitter or use the PIECAL 434 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 434 in place of a 2 Wire transmitter. Uses any loop power from 2 to 60 V DC.
• Read loop current Check controller outputs or measure the milliamp signal anywhere in the loop. The PIECAL 434 measures 0.000 to 24.000 mA (-25.00 to 125.00%) signals with greater accuracy than a typical multimeter.
• Power & measure 2 wire transmitters The PIECAL 434 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 434 can measure from -60.00 to +60.00 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 434 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.
