PIECAL 334Plus
Automated 4-20mA Loop Calibrator

With the PIECAL 334Plus 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 334Plus to simultaneously power your 2-wire transmitter and measure its output.

• Calibrate milliamp instruments
  Source 0.00 to 24.00 mA & -25.0 to 125.0% of 4-20 mA
  Read 0.00 to 52.00 mA
  Read -99.99 to 99.99 V
  Simulate 2-wire transmitter, power & read transmitters
  Menu selectable 250Ω resistor for HART compatibility            
• Calibrate with accuracy
  Accurate to ±(0.02% of reading + 0.002 mA)  
• 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
