1. SAFETY INFORMATION
The following safety information must be observed to insure
maximum personal safety during the operation at this meter.
1) When measuring voltage ensure that instrument is not
switched to the current range, resistance range, diode and
continuity range, capacitance range or temperature range.
2) Use extreme care when measuring voltage above 50V.
especially from sources where high energy is existed.
3) Avoid making connections to "live" circuits whenever possible.
4) Before making resistance measurements, diode or continuity
test, capacitance test or temperature test, ensure that the
circuit under test is de-energized.
5) Always ensure that the correct function and range is selected.
6) Extreme care should be taken when using the instrument to
conjunction with a current transformer connected to the
terminals if an open circuit occurs.
7) Ensure that the test leads and probes are in good condition
with no damage to the insulation.
8) Take care not to exceed the over-load limits as given in the
specifications.
9) Before opening the cover of the battery cabinet to replace
batteries. disconnect the test leads from any external circuit,
set the selector switch to "OFF" position.
10) Keep the fingers after the protection ring when measuring
through the instrument lead.
11) Change the battery when the symbol “ ” appears to avoid
incorrect data.

4) Read the result from the LCD panel.
Caution:
a) Capacitors should be discharged before being tested.
b) When testing large capacitance, it will take longer time before
the final indication(For 1uF~99.99mF range, it will take about
4~7 seconds).
c) When testing small capacitance（≤1uF）, to assur the
measurement accuracy, first press "REL", then go on
measureing.
Max.input over-load: 250V rms＜10sec
3.4 Frequency Measurement

3) connect the probes across the source or load under
measurement.
4) Read the result from the LCD panel.
3.5 Temperature Measurement
1) Set the Rotary switch to "℃/℉" position.
2) Connect the black test lead of the sensor to "T-COM"
socket and the red test lead to the " T+ " socket.
3) Put the sensor probe into the temperasure field under
measurement.
4) Read the result from the LCD panel.
Max.input over-load: 250V rms＜10sec
A. The temperature function shows the random number at ordinary
times, must insert the thermocouple in temperature test hole while
examining temperature.

Before this measurement, disconnect the test lead with the
meter for safety.
4. CARE AND MAINTENANCE
4.1 CARING FOR YOUR MULTIMETER
Your Digital Multimeter is an example of superior design and
craftsmanship. The following suggestions will help you care for
the multimeter so you can enjoy it for years.
1) Keep the multimeter dry. If it gets wet, wipe it dry immediately.
Liquids can contain minerals that can corrode electronic circuits.
2) Use and store the multimeter only in normal temperature
environments. Temperature extremes can shorten the life of
electronic devices, damage batteries and distort or melt plastic parts.
3) Handle the multimeter gently and carefully. Dropping it can
damage the circuit boards and cause and can accuse the
multimeter to work improperly.
4) When take current measurement, keep the cable at the center
of the clamp will get more accurate test result.
5) Keep the multimeter away from dust and dirt, which can cause
premature wear of parts.
6) Wipe the mutimeter with a damp cloth occasionally to keep it
looking new. Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the multimeter.
7) Use only fresh batteries of the required size and type. Always
remove old or weak batteries. They can leak chemicals that
destroy electronic circuits.
8) Please take out the battery when not using for a long time.
4.2 9Volt battery replacement
1) Ensure the instrument is not connected to any
extemal circuit. Set the Rotary switch to "OFF" position and
remove the test leads from the terminals.
2) Open the cover of the battery cabinet by a screwdriver.
3) Replace the old batteries with the same type batteries.
4) Close the battery cabinet cover and fasten the screw.
