PIECAL 434

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
