3. MEASURING INSTRUCTION
3.1 DC/AC Voltage
1) Connect the black test lead to "T-COM" socket and red test
lead to the " T+V
ΩHz " socket.
2) Set the Rotary switch to "
V
" position Push the SELECT
key to desired DC /AC test
3) connect the probes across the source or load under
measurement.
4) Read the result from the LCD panel.
3.2 Resistance
、
Diode and Audible continuity
Measurement
1) Connect the black test lead to " T-COM " socket and red test
lead to the " T+V
ΩHz " socket.
2) Set the Rotary switch to desired "
Ω
" position, the
present function is resistance measurement, if it is other
function, push the SELECT Key to select .Diode and Audible
continuity
3) Push "SELECT" to select diode test.
4) Connect the black and red test probe to the cathode (-)
and anode (+) ends of diode to be tested
repectively, read the forward voltage drop (junction) value
from the display. If reverse connected the probes to diode,
display shows over-load.
5) Push "SELECT" to select Audible continuty test.
6) Connect the probes across circuit to be tested, the beeper
sounds continuously if the resistance is less than approx. 5
0Ω
7) Connect the probes across circuit to be tested.
8) Read the result from the LCD panel.
Caution: Ensure that the circuit to be tested is "dead".
Max.input over-load: 250V rms
<
10sec
3.3 Capacitance Measurement
1) Connect the black test lead to "T-COM" socket and red test
lead to the "T+V
ΩHz" socket.
2) Set the Rotary switch to desired "
CAP
" position.
3) Connect the probes to the capacitance to be tested.
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
1) Connect the black test lead to "T-COM" socket and red test
lead to the " T+V
ΩHz " socket.
2)Set the “
Hz/Duty
” key to desired Hz/Duty test
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.
B.
This meter inclosure WRNM-010 type contact thermocouple
limit temperature is 250

shortly ) ;
C.
Please don't change the thermocouple at will , otherwise we
can't guarantee to measure accuracy ;
Please don’t importing the voltage in the temperature function.
D. Please use special probe for test high temperature.
3.6 DC/AC Current Measurement
1
) Set the Rotary switch to desired “600A
”or “3000A
”
position.
2) Set the SELECT key to desired DC or AC test
3) Press the "REL" Key, the display show "0", ACA auto Zero.
4) Open the clamp by pressing the jaw-opening handle and insert
the cable to be measured into the jaw.
5) Close the clamp and get the reading from the LCD panel.
Note:
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.
