HP-990B Smart SMD Chip Tester Digital SMD Meter Handheld Resistance Capacitance 4000 Counts Ohm Tester Professional Multimeter Descriptions: The meter is a handheld and battery-powered small tool, which is specially applied to measure SMD(Surface Mounted Device). The meter can test resistance, capacitance, battery, diode, Zener/LED and continuity. Besides, it is displayed by large LCD and it will be off automatically after 15minutes if no button is pushed during this period. Specifications: Resistance: 400Ω~40MΩ Capacitance: 4nF~200uF Display: 4000counts Range Select: Auto Battery Test Diode Test Continuity Buzzer Zener/LED test: Open Voltage more than DC 20V Relative Value Auto Power Off Power Supply: 2*1.5V AAA battery(battery not included) Dimension: 207*36*26mm Resistance: 400Ω/6KΩ/40K/400KΩ±2.0%rdg; 4MΩ/40MΩ±2.5%rdg Capacitance: 4nF/40nF/400nF/4μF±2.5%rdg; 200μF±3.0%rdg Diode Test: Open Voltage: 1.5V, Testing Current: 2mA Continuity Check: When the resistance is less than approx.30Ω,The Buzzer sounds. Zener/LED: Open Voltage: MIN 20V, Testing Current: Appr. 1mA Battery Power: Loading Current: Approx. 10mA±1.5rd% Note: 1. Due to the light and screen difference, the item's color may be slightly different from the pictures. 2. Please allow 1-3cm differences due to manual measurement.
