Model UT30B/C/D/F: OPERATING MANUAL

UT30 series Multimeter is 3 1/2 digits with steady operations,fashionable

structure and highly reliable hand-held measuring instrument. The meter

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

Temperature, Diode, Transistor hFE, and Continuity. It is an ideal tool for

maintenance.

A. Introduction

Model UT30B/C/D/F: OPERATING MANUAL

This Meter complies with the standards IEC61010-1: in pollution degree 2, overvoltage

category (CAT I 600V, CAT II 300V) and double insulation.

CAT. I: Signal level, special equipment or parts of equipment, telecommunication,

electronic, etc., with smaller transient overvoltages than overvoltages CAT. II.

CAT. II: Local level, appliance, PORTABLE EQUIPMENT etc., with smaller transient

overvoltages than CAT. III

Use the Meter only as specified in this operating manual, otherwise the protection

provided by the Meter may be impaired.

B. Safety Information

C.Rules for safe operation(1)

l Use the meter only as the rules specified in this manual, otherwise,

the protection provided by the meter may be impaired.

l Do not operate the meter unless the bottom case has been closed as

terminal can carry voltage.

l Inspect the insulation of the test leads and make sure there is no

damage to the test leads before using the meter.

l As soon as the battery indicator’s“ ” appear, replace the battery to

ensure accurate readings.

l Set the meter to suitable function and range before each measurement.

l Tested values over the maximum range of each measurement can

cause damages to the meter or electric shock to users.

l To avoid damages of the meter, do not turn the rotary switch during

measurement

Model UT30B/C/D/F: OPERATING MANUAL

l When measuring voltage higher than DC 60V or AC 30Vrms, pay

extra attention to avoid electric shock.

l Make sure to replace right type and right rating fuse.

l Do not operate or store the Meter under high temperature or humid

condition.

l Do not change internal circuit to avoid damages to the meter and

danger to the user.

l Periodically wipe the case with damp cloth and mild detergent. Do

not use abrasives and solvents.

l The meter is designed to withstand the stated maximum voltages.

If it not possible to exclude without doubts that impulses,transients,

disturbance or for other reasons these voltages are exceeded,a

suitable prescaler (1:10) must be used.
