Pure sine waves are rare in modern facilities due to digital switching power supplies. The True-RMS calculation engine in the 191 model has been overhauled to evaluate heavily distorted, non-sinusoidal square and sawtooth waveforms with a total harmonic distortion (THD) profile of up to 40%, keeping measurement error margins tight at Real-World Field Applications Industrial Automation and VFD Diagnostics
includes all fundamental testing capabilities but integrates high-precision thermal diagnostics. Boasting a 0.1°C temperature resolution across a wide operational spectrum (-40°C to 400°C / -40°F to 752°F), it is heavily favoured by climate control engineers, industrial motor technicians, and HVAC specialists.

: Though heavily shielded, keeping the main chassis away from unshielded high-voltage transformers prevents residual noise induction. Pure sine waves are rare in modern facilities
