Victor VC70D User Manual

Digital multimeter
1 / 25
Ⅰ. Overview
As a kind of intelligent 3 5/6 digital multimeter with automatic identification, steady performance and high
reliability, this meter is equipped with LCD display device with the text height of 33mm which features
clear reading, direct-viewing display and convenient operation. It can be used to measure DC voltage, AC
voltage, DC current, AC current, resistance, capacitance, frequency, diode and continuity test; meanwhile, it
is available for unit symbol display, data retention, the measurement of maximum and minimum value,
automatic/manual range switching, automatic power off and alarm function. The complete machine takes a
switching integrated circuit which can directly drive LCD microprocessor and double-integrating A/D and a
digital display drive offering high resolution and high precision. Since the meter features complete
functions, high measurement accuracy and convenient operation, it is the ideal tool in laboratory and
factory as well as for radio fans and family.
Ⅱ. Open-package Inspection
Open the package box and take out the meter, check carefully if the following accessories are absent or
damaged. If there is any absence or damage, please contact the distributor immediately.
