

Do not replace batteries if the Instrument is wet.



Ensure that the test leads are firmly inserted into the terminal.



Ensure that the Instrument is powered-off if opening the battery cover.

Caution



Set and ensure the Range switch to the appropriate position before making measurement.



et the Range switch to“ OFF” position after use and remove the test leads.



Remove the batteries if the Instrument is to be stored and will not be in use for a long period.



Do not use the Instrument when mark

displays.



Do not use or keep the Instrument in high-temperature, high-humidity, explosive, strong electromagnetic
and dewy environment or expose to direct sunlight.



Do not use abrasives or solvents. Use a damp cloth with neutral detergent for cleaning the instrument.



Do not store the Instrument if it is wet. Store it after it dries.
