6. Do not overload voltage or current on EITHER
between terminal and terminal OR between terminal
and grounding which indicate on meter limitation.
7. The rotary switch should be placed in the right
position and no any changeover of range shall be
made during measurement is conducted to prevent
damage of the Meter.
8. Do not use or store the meter in an environment
of high temperature, humidity, flammable and
electromagnetic environment. The performance of
the meter may deteriorate after dampened.
9. The internal circuit of the meter shall not be
altered at will to avoid damage of the meter and any
accident
10. Replace the battery as soon as the battery
indicator “ ”Appears. With a low battery, the
meter might produce false readings that can lead to
electric shock and personal injury.
11. Turn the meter off when it is not is use and take
out the battery when not using for a long time.

Operating Manual
Overview
Digital Bench-Type Multimeter Model UT801 is the
maximum reading 1999 and 3 1/2 digits and UT802
is the maximum reading 19999 and 4 1/2 digits,
both models are in manual range, DC / AC current
type digital multimeter, This is also the extra large
characters in LCD display backlight with full function,
full measurement and full overload protection as well
as a good product design outlook, In addition to all
the conventional features include DC/AC voltage,
DC/AC current, resistance, frequency, capacitance,
temperature
℃
, Transistor hFE
、
diode and
continuity buzzer.
This operating manual covers information on
safety and cautions. Please read the relevant
information carefully and observe all the Warnings
and Notes strictly.
Unpacking Inspection
Open the package case and take out the Meter.
Check the following items carefully to see any missing
or damaged part. If you find any missing or damage,
please contact your dealer in your country.
● Operating Manual 1 piece
● Test Lead 1 pair
● Alligator Clip 1 pair
● K Type Temperature Probe 1 piece
( For the temperature under 230
℃
testing)
● Multi-Purpose Socket 1 piece
● Power Cord 1 piece
(AC220V 50Hz DC9V/200mA)
Safety Information
This Meter complies with the standards
IEC61010-1 in pollution degree 2, overvoltage
category (CAT II 1000V) and double insulation. If you
can not follow up this operating instruction to use the
meter and it reduces the chance to have an using
protection.
1. Before using the Meter and Test Leads inspect
both items. Do not use the Meter and Test Leads
if it is damaged or the case (or part of the case) is
removed or no reaction on LCD display. Prohibited
to use the meter without housing or housing without
screw fix up in order to avoid possible electric shock
or to avoid possible damage to the meter or to the
equipment under test.
2. If the damage of test leads, use only the same
model number or identical electrical specifications
replacement parts.
3. Do not use your finger to touch on any testing
cable, connector, unused terminal input or circuit
during the testing stage
.
4. When the meter working at an effective voltage
over 60V in DC or 30V rms in AC, special care should
be taken for there is danger of electric shock.
5. Selecting the correct terminal input and turn the
rotary switch to select the measuring function. In
case of no any idea on the value input of the current,
just simply test from the high value to low one.
