PIECAL 434
Automated Diagnostic 4-20 mA 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.

• Calibrate milliamp instruments
  Source 0.000 to 24.000 mA & -25.00 to 125.00% of 4-20 mA
  Read -99.99 to 99.99 V
  Simulate 2-wire transmitters, power & read transmitters
  Menu selectable 250Ω resistor for HART compatibility
• Calibrate with laboratory accuracy
  Accurate to ±(0.01% of reading + 0.002 mA)
  PIECAL 434 is more accurate than many similar calibrators - within ±0.004 mA at 20 mA output!
• Easy-to-read backlit display
• Locate loop current leakages
  Automatic indication of loop current and leakage current. Measure ground current leakage from faulty wiring, flooded conduit and corrosion bridges. Leakage typically appears as a Zero Shift and helps you decide if the transmitter needs calibration or if there is a problem in the loop wiring.
• Faster calibrations
  Three output EZ-CHECK switch
  2 speed EZ-DIAL
  Stepping & ramping
