HK116B Smart SMD Tester
Product Description
The HK116B elevates SMD diagnostics with 60V DC voltage measurement, LED/Zener diode testing, and auto/manual ranging. Its expanded toolkit (capacitor discharge, battery test) makes it ideal for advanced circuit troubleshooting while retaining the HK116A’s compact form.
Key Highlights
Advanced Component Analysis: Tests LEDs, zeners, batteries
Dual Ranging Modes: Auto + manual selection flexibility
Enhanced Workflow: Capacitor discharge + relative mode
Power Management: Auto-off + low-battery indicator
