PIE Model 531 – Pocket Size mA Calibrator. Includes FREE NIST Traceable Certificate of Calibration (Optional Carrying Case 020-0205)
• Easy to use
With the PIECAL 531 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 531 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 graph
The Quick Reference Bar Graph indicates the input and output level
to the PIECAL 531 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 531 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 531 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 531 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 531 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.
