Safety Information

Digital Multimeter UT56 (hereafter referred to as "the

Meter") is 20000-count hand-held instruments

featuring stable performance, versatile functions, high

degree of reliability&accuracy. It is designed with

large-scale integrated circuits, dual integral A/D

converter as well as overloaded protection. The series

can measure AC/DC voltage, AC/DC current,

resistance, capacitance, frequency, transistor, diode

and continuity, making the series a perfect tool for

users.

Caution:

1) At 200M

Ω range, test lead is short circuit, the

LCD display 1000 digits, subtract the 1000

digits from the measured reading during

measuring.

2) At 200

Ω range, short the test lead first to display

the resistance value of the test leads. subtract

that resistance value from the measured reading

to obtain the being measured object's correct

value .
