The HoldPeak HP-990B is a specialized handheld digital SMD (Surface Mounting Device) tester designed for precise measurement of small components like resistors, capacitors, and diodes. It features a tweezer-like probe design with gold-plated pins to reduce contact resistance and prevent rust.
Key Specifications & Ranges
Display: 4,000 count LCD.
Resistance: to with to accuracy.
Capacitance: to with to accuracy.
Zener/LED Test: Open voltage greater than DC 20V.
Battery Test: Specifically includes a battery power measurement function (approx. 10mA loading current).
Continuity: Audible buzzer sounds if resistance is less than approx.
Core Features
Auto Scan & Range: Automatically identifies and measures components like resistors and capacitors to save time.
Relative Value (REL): Allows users to clear zero for low-value capacitance measurements to improve precision.
Ergonomic Design: The case is covered with a thermo plastic elastomer for a comfortable, non-slip grip.
Auto Power Off: Conserves battery life by turning off after approx. 15 minutes of inactivity.
Dimensions: Approximately
, weighing roughly 182g.
