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 andmeasure all your current signal instruments in a 4 to 20 milliamp DC loop. Itcan 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 tosimultaneously power your 2
Wire Transmitter and measure its output.
Source milliamps
Calibrate recorders, digital indicators, strokevalves or any instruments
that get their input from a 4 to 20 mAloop. Easily set any value quickly to within 0.01 mA with the adjustable digitalpotentiometer “DIAL“or use preset 4.00 mA (0.0%) and20.00 mA (100.0%) EZ-CHECKsettings.
Monitor changes with bar graph
The Quick Reference Bar Graph indicates the inputand output level
to the PIECAL 531 in % of 4-20 mA with 1.0%resolution. The Quick Reference Bar Graph flashes when signals outside thenormal operating range is detected.
Power saving output
Choose High Power 24V output to drive loops withup to 1200 Ohm
loads or extend battery life by selecting LowPower 15V output which drives loops with up to 600 Ohm loads.
Calibrate using loop power
Check loop wiring and receivers by using thePIECAL 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 milliampsignal anywhere in the loop. The PIECAL 531 measures 0.00
to 24.00 mA (-25.0 to 125.0%) signals withgreater accuracy than a typical multimeter.
Power & measure 2 wiretransmitters
The PIECAL 531 can simultaneously output 24V DCto power any and all devices in a process loop using the
internal batteries and internal switching powersupply, while measuring the output of a 2 Wire Transmitter and any other loopdevices. Powers HART transmitters with built-in 250 ohm resistor simplifyinghookups with HART communicators.
Evolutionary design
PIECAL Calibrators are designed and built bymembers 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 withlarger digits and bar graph, rugged switches, belt clip and a batterycompartment for fast battery
changes.
