The Fluke 8050A-01 is a 4.5-digit digital multimeter engineered for precision electrical measurements across DC voltage, AC voltage, current, resistance, and specialized functions including diode testing and dBm measurement. This portable instrument delivers 0.03% basic DC accuracy with true RMS capability from 20 Hz to 50 kHz, making it suitable for electronics troubleshooting, field service, and calibration work. The model 8050A-01 integrates rechargeable NiCad batteries providing 10 hours typical operating time, alongside AC line power operation (90–264 V, 47–440 Hz), enabling both cordless field deployment and stationary bench use. An automatic polarity indicator and overrange display enhance readability on the 4.5-digit LCD. Built-in transient protection rated to 6 kV, 10 microseconds, combined with overload protection and a 500 V dc maximum common mode voltage rating, safeguards the instrument against typical field hazards. Weighing 1.08 kg and measuring 22 cm × 6 cm × 25 cm, the meter fits standard equipment racks and portable kits.
