b) This device adopts charging mode to measure capacitance, so when testing
large capacitance, it will take longer time before the final indication, and the
larger capacitor, the longer the time (For 100uF range, it will take about 15
seconds).
c) When testing small capacitance, to assure the measurement accuracy, first
press "REL", then go on measuring.
Max. input over-load: 250V rms＜10sec
3.6 Frequency measurement
1) Connect the black test lead to "COM" socket and red test lead to the "VΩHz"
socket.

from the display.
Max. input over-load: 250V rms＜10sec
3.7 Temperature measurement
1) Connect the black test lead of the sensor to "T-" socket and the red test
lead to the "T+" socket.
2) Set the selector switch to " " position.
3) Put the sensor probe into the temperature 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

4. CARE AND MAINTENANCE
4.1 CARING FOR YOUR MULTIMETER
Your Digital Multi meter is an example of superior design and craftsmanship.
The following suggestions will help you care for the multi meter so you can
enjoy it for years.
1) Keep the multi meter dry. If it gets wet, wipe it dry immediately. Liquids can
contain minerals that can corrode electronic circuits.
2) Use and store the multi meter 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 multi meter gently and carefully. Dropping it can damage the
circuit boards and cause and can accuse the multi meter 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 multi meter away from dust and dirt, which can cause premature
wear of parts.
6) Wipe the multi meter with a damp cloth occasionally to keep it looking new.
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean
the multi meter.
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 external 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.
