CAUTION
● Always make sure to check the Function Selector Switch is setting to the appropriate range before starting measurement.
● Do not expose the instrument to the direct sun, high temperature and humidity or dewfall.
● When the instrument will note be in use for a long period, place it in storage after removing the batteries.
● Use a cloth dipped in water or neutral detergent for cleaning the instrument. Do not use abrasives or solvents.
● Allowable measurement time at 10A range of current function is 15 seconds. If you carry on making measurement continuously over 15 seconds, it can cause
instrument damage.
Please refer to following explanation of the symbols marked on the instrument or in the manual.
