Same-day response on quotes. ISO/IEC 17025 accredited calibration available.
Overview
The PIECAL 334Plus adds diagnostics and finer resolution to everyday loop work. Source and read 0.000 to 24.000 mA (−25.00 to 125.00% of 4–20 mA), simulate two-wire transmitters, and power HART transmitters with the built-in 250 Ω resistor. Patented Ground Leak Detection helps find moisture and wiring faults that ordinary loop calibrators miss.
EZ-CHECK points at 4 and 20 mA are ≤ ±(0.025% of span) (±0.005 mA); full-range source accuracy is ≤ ±(0.05% of 24 mA span) (±0.012 mA). Loop drive is 1200 Ω at 20 mA with leak detection off (950 Ω with HART resistor). Automatic stepping and a backlit display speed plant rounds.
Includes batteries, Certificate of Calibration Card, rubber boot, deluxe carrying case, and test leads per the datasheet. Made in the USA with NIST-traceable calibration.
