PIECAL Pocket-Cal Milliamp Calibrator

With the PIECAL 134 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 0.00 to 24.00 mA, Simulate a 2 Wire Transmitter or use the PIECAL 134 to simultaneously power your 2 Wire Transmitter and measure its output.

Features

• Simulate a 2 Wire Transmitter or use the PIECAL 134 to simultaneously power your 2 Wire Transmitter and measure its output.
• 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 0.01 mA with the adjustable digital potentiometer "DIAL" or use preset 4.00 mA (0.0%) and 20.00 mA (100.0%) EZ-CHECK™ settings.
• Monitor changes with bar graphThe Quick Reference Bar Graph indicates the input and output level to the PIECAL 134 in % of 4-20 mA with 1.0% resolution. The Quick Reference Bar Graph flashes when signals outside the normal operating range is detected.
• Power saving output Choose High Power 24V output to drive loops with up to 1200 Ohm loads or extend battery life by selecting Low Power 15V output which drives loops with up to 600 Ohm loads.
• Calibrate using loop power Check loop wiring and receivers by using the PIECAL 134 in place of a 2 Wire transmitter. Uses any loop power from 2 to 42 V DC.
• Read loop current Check controller outputs or measure the milliamp signal anywhere in the loop. The PIECAL 134 measures 0.00 to 24.00 mA (-25.0 to 125.0%) signals with greater accuracy than a typical multimeter.
• Power & measure 2 wire transmitters The PIECAL 134 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.
• 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 134 improves upon other brands by including a larger display with larger digits and bar graph, rugged switches, belt clip and a battery compartment for fast battery changes.
