Key Features
Multi‑signal capability – Outputs and measures DC voltage (V, mV), current (mA), resistance, frequency, pulse, and thermocouple (TC) signals. Also supports RTD simulation for temperature calibration.
High accuracy – Basic accuracy up to 0.02% for critical calibration tasks. Digital temperature compensation ensures stable readings in changing conditions.
Simultaneous operation – Output and measure at the same time. Perfect for transmitter calibration where you need to source one signal while reading another.
24V loop power – Provides DC 24V to power two‑wire transmitters directly. No external power supply needed on site.
User‑friendly interface – High‑contrast LCD with 5‑digit resolution. Intuitive keypad and rotary encoder for quick value adjustment.
Handheld & portable – Battery‑powered, lightweight design. Ready for field use, plant floors, and control cabinets.

Smart Output Modes
Step Output – Increase or decrease output by a fixed increment (e.g., 4→8→12→16→20 mA). Ideal for checking linearity.
Ramp Output – Output rises and falls automatically in a triangle wave pattern. Tests valve response and system dynamics.
Custom Curve Programming – Program up to 100 points of output versus time. Simulate complex process profiles for controller testing.
25% Step & Auto Ramp – Quick 4‑20mA testing with one‑button 0%, 25%, 50%, 75%, 100% steps.
