Description
This portable loop calibrator delivers stable and highly accurate signal sourcing for process control applications. It supports 4–20 mA, 0–20 mA, and 0–24 mA output with 1 μA resolution and ±0.025% accuracy, helping technicians verify transmitters, control loops, and PLC inputs with confidence.
The calibrator also provides DC voltage output up to 24 V with excellent precision. Built-in Auto-Ramp and Easy Step (1–100%) functions simplify loop testing and simulation tasks. The just-type-in number interface speeds up operation and reduces setup errors.
Safety features include an open-loop beeper and short-circuit warning, which help protect equipment during testing. With its compact body, clear LCD display, and battery operation, the unit works well for both field service and bench calibration.
