This unit
The Tenma 72-7730A is a handheld True RMS digital multimeter engineered for electrical and electronic testing across industrial, field service, and laboratory environments. This 4.5-digit (20,000-count) instrument delivers precise AC/DC voltage, current, resistance, capacitance, frequency, and temperature measurements with auto-ranging simplicity. The 100 kHz bandwidth supports transient analysis, while integrated duty cycle measurement (10% to 90%), diode testing, and continuity detection expand troubleshooting capability.
USB connectivity enables PC-based data logging of up to 100 records, making it suitable for continuous monitoring and documentation workflows.

Tenma 72-7730A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Tenma 72-7730A. Calibration covers DC voltage accuracy at all ranges, AC voltage (True RMS) accuracy at 50 Hz, 1 kHz, and 10 kHz, DC current accuracy, resistance accuracy at all decade ranges, frequency accuracy, and diode test voltage. Fluke 87V and 289 also include capacitance and temperature calibration.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Tenma 72-7730A faults: blown input fuse, worn input jacks, display segment failure, relay contact wear on bench DMMs. Common faults include worn input jacks (banana socket contact wear on the mA and COM terminals), blown input fuses (especially the 440 mA HRC fuse), and display segment failures. Keithley 2000/2001/2002 bench DMMs commonly develop relay contact wear affecting resistance accuracy after extended service.
