Caution:
a) Capacitors should be discharged before being tested.
b) When testing large capacitance, it will take longer time before
the final indication(For 100uF range, it will take about 15
seconds).
c) When testing small capacitance, to assur the measurement
accuracy, first press "REL", then go on measureing.
Max.input over-load: 250V rms＜10sec
3.5 WATT measurement
1) Connect the black test lead to "T-COM" socket and red test
lead to the " U" socket.
2) Set the Rotary switch to desired "40kW "or"400kW" position.
3) Connect the red test head to the live wire of the load by test
and connect the black test head to the N-wire of the load by
test, Push the " REL " Key Until the meter display “000”.
4) Open the clamp by pressing the jaw-opening handle and
clamp the live wire of the load by test, Let the live wire through
The clamp from surface of the meter，The meter will display
working power of the load by test。
Notice：
If meter display negative,reversed the clamp or test lead.
3.6 Cosα TEST
1) Set the Rotary switch to desired " Cosα" position.
2) The way of Connection wire,Please reference 3.5 item 1) ,3),4)
3) The meter will display power factor of the load by test。
Notice：The meter will display “OL”when test value is negative
Cosα ，then reversed the clamp or test lead.

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 selector 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.
