The FNIRSI SG-004A is a multifunction process calibrator for instrument technicians. It sources and reads current, voltage, frequency/PWM, millivolt and thermocouple signals, and simulates resistance and RTD sensors such as Pt100 and Cu50.
Current and voltage accuracy is ±(0.02% + 0.003) with 0.001 resolution, and it covers ten thermocouple types (S, B, E, K, R, J, T, N and two tungsten-rhenium types). Programming mode, history records, real-time curves and Modbus make it useful for both bench calibration and field loop checks.
