Multi-Function Measurement for Advanced Field Troubleshooting
The HK39H is the most versatile model in the HK39 smart pocket series. It combines AC and DC voltage, AC and DC current, resistance, capacitance, frequency and duty-cycle measurement in a 130 g instrument. This expanded capability is designed for technicians who diagnose powered equipment, electronic controls, appliances and field wiring but still want a meter that fits comfortably in a small tool kit.
A 5,999-count display provides the highest display count of the three models. The meter covers current ranges from microamps to 600 mA, capacitance up to 60 mF, resistance up to 60 MΩ and frequency up to 10 MHz. Its 0.1%–99.9% duty-cycle range adds another useful measurement for suitable pulsed and control signals.
SMART/AUTO range selection helps reduce manual adjustments during varied diagnostic work. True RMS capability, NCV detection and live wire recognition support electrical testing, while diode, continuity and data-hold functions cover common troubleshooting tasks. A backlit LCD, work flashlight and automatic power-off round out a feature set intended for mobile technicians and bench users alike.

Typical Applications
Powered Equipment Diagnostics
Measure supply voltage and low current while checking the operation of appliances, small machines and electronic equipment.
Control-Signal Testing
Use frequency and duty-cycle modes to assess suitable periodic signals in control boards, switching circuits and related systems.
Electronics Bench Work
Combine µA/mA current measurement with resistance, capacitance, diode and continuity tests during circuit development or repair.
Appliance and Electromechanical Service
Check capacitors, trace wiring faults and investigate electrical behavior across motors, actuators and household or commercial equipment.
Mobile Maintenance and Commissioning
Carry one compact meter for a broad set of voltage, current, component and signal checks during field visits.
Compare HK39E, HK39G and HK39H
Choose the HK39H when current and duty-cycle measurement, a 5,999-count display and the widest measurement coverage are priorities. If current measurement is unnecessary, the HK39G smart multimeter with capacitance and frequency offers a focused alternative. For core voltage, resistance and continuity work, see the HK39E essential smart pocket multimeter.
