It is a professional capacitance meter with wide measuring range, stable performance and accuracy result. With large LCD display and white backlight, easy to read. Features: This meter can be used to measure capacitance of cable and switch. Applied with CMOS double-bevel A/D convertor that is automatic in zeroing and polar selection. Wide measuring range, data hold function, it is more practical. Large LCD display with white backlight, easy to read. Maximum display value: 1999(3 1/2). Low battery indication. Note: Please ensure that all measured capacitor are discharged before testing.
