Description

The handheld multifunction process calibrator is designed for accurate and reliable testing in industrial and field environments. It can source 4–20 mA, 0–20 mA, and 0–24 mA signals with 1 µA resolution. The device also sources DC voltage from 0–12 V and 0–100 mV and supports simultaneous measurement of AC/DC current and voltage with True RMS.

It offers frequency sourcing and measurement from 1 Hz up to 39.999 MHz and calibrates 11 types of thermocouples. Users can also measure resistance, continuity, and diode voltage safely with overload protection. The calibrator supports HART communication with a selectable 250 Ω resistor, allowing smooth integration with HART-enabled devices. Auto ramp and step functions streamline mA, voltage, and temperature testing. The device provides clear warnings for overload, open output, or short circuits, ensuring safe operation.
