1. Safety Warnings This instrument has been designed, manufactured and tested according to the following standards. IEC 61010-1 Measurement CAT.Ⅲ 300V Pollution degree 2 IEC 61010-031 IEC 61326 This instruction manual contains warnings and safety rules which must be observed by the user to ensure safe operation of the instrument and retain it in safe condition. Therefore, read through these operating instructions before using the instrument.
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.

Preparation 5-1 Checking Battery Voltage Set the Function Selector Switch to other positions except the OFF position.
(2) Set the Function Selector Switch to " " position.(Then, "AC", "Auto", and "V" symbols are indicated on the display.) (3) Connect the test leads to the circuit under test. Measured value is indicated on the display. Note) When you make measurement of the voltage less than 0.1V at the AC6V range, the measurement value cannot be indicated correctly. Even if short-circuit the input line at the range of AC6V, 1∼3dgt may remain indicated. In that case, by pressing "REL" Key, "0" will be indicated.
(5) Connect the test leads to the circuit under test so the instrument is in the series. (6) Power on the circuit under test. (7) Measured value is indicated on the display. 6-2-4 AC Current Measurement (up to 10A) CAUTION ● For safety sake, the measuring time on 10A range should be 15 seconds or less. Interval time between 2 measurements should be greater than 15 minutes.
(Then, " " and "Ω" symbols are indicated on the display.) Make sure that the "OL." symbol is indicated on the display at this bout, then short the test lead tips and check "0" is indicated on the display and check if the buzzer beeps. (4) Connect the test leads to both ends of the resistance under test. Measured value is indicated on the display. The buzzer beeps below about 100Ω. Note) Even if short the test lead tips, indicated value may not be "0".
7. How to use Function Switches 7-1 SELECT Key This key is to chose the measuring function at Ω/ Diode Check/ Continuity/ function and Current function(uA, mA, A). Actions at each function are as below. ● Ω/ Diode Check/ Continuity function When setting the instrument to "Ω/ Diode Check/ Continuity" function, "Ω"measuring mode has been selected in the initial condition. By pressing "SELECT" Key, measuring mode changes.
8. Auto Power Off Auto power off function operates when about 15minutes passed after power on this instrument. When Auto power off function operates and the instrument powered off, the power-off statue returns to normal by pressing any key. And it is possible to release the Auto power off function. Turn the Function Selector Switch from OFF position to the function you want with pressing "SELECT" Key, and power on the instrument. 9.
