The Fluke 117 CAL is a True-RMS digital multimeter purpose-built for electricians and technicians in commercial and industrial environments. It delivers precise measurements across voltage, current, resistance, and frequency with a 6,000-count display and 33-segment bar graph. The instrument includes NIST-traceable calibration certification, VoltAlert™ non-contact voltage detection, AutoVolt automatic AC/DC selection, and LoZ mode to eliminate ghost voltage errors. True-RMS capability ensures accuracy on both linear and non-linear loads—critical for diagnosing modern electrical systems.
