User Manual
A. Introduction
This product is a battery-powered, true-rms, auto-ranging digital multimeter with
a 4000 counts, LCD display and backlight/flashlight.
B. Safety Information
To avoid possible electrical shock, fire, or personal injury, please read all safety
information before you use the product.
(1) Do NOT exceed the “maximum value” indicated in the Specification.
(2) Examine the connection of the test leads and the insulation of the product
before measuring voltage higher than 36V DC or 25V AC.
(3) Disconnect the test leads from the circuit before changing the mode。
(4) Misuse of mode or range can lead to hazards, be cautious. “OL” will be shown
on the display when the input is out of range.
