3 1/2 DIGITS DIGITAL MULTIMETER 600.
Read the Users Manual thoroughly before use. SAFETY INFORMATION The digital multimeter has been designed according to IEC-1010 concerning electronic measuring instruments with an over voltage category (CATI) and pollution degree 1. ELECTRICAL SYMBOLS AC (Alternating Current) DC (Direct Current) Important safety information. Refer to the manual. Dangerous voltage may be present. Earth ground Fuse Conforms to European Union directives Double insulated Do not attempt to make any repairs yourself.
WARNING To avoid possible electric shock or personal injury, follow these guidelines: • Do not use the meter if it is damaged. Before you use the meter, inspect the case. Pay particular attention to the insulation surrounding the connectors. • Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged test leads before you use the meter. • Do not use the meter if it operates abnormally. Protection may be impaired.
CAUTION To avoid possible damage to the meter or to the equipment under test, follow these guidelines: • Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance. • Use the proper terminals, function, and range for your measurements. • Before measuring current, check the meter’s fuses and turn power OFF to the circuit before connecting the meter to the circuit. • Remove test leads from the Meter before opening the Meter case.

DIODE AND AUDIBLE CONTINUITY TEST Range Description Test Condition The approx. forward The forward DC current voltage drop of the diode is approx. 1mA, the will be displayed on the reversed DC voltage is LCD. approx. 2.8V. If the resistance of the circuit under test is less Open circuit voltage is than 40Ω, the built-in approx. 2.8V. buzzer will sound. TRANSISTOR TEST Range hFE PNP & NPN 0~1000 Test Current 1b=10µA Test Voltage Vce=2.8V OPERATING INSTRUCTION DC VOLTAGE MEASUREMENT 1.
DC CURRENT MEASUREMENT 1) Connect the red test lead to the “mA” jack and the black test lead to the “COM” jack. 2) Set the range switch to the desired “ ” range. If the current to be measured is not known beforehand, set the range switch to the range and then turn down range by range until satisfactory resolution is obtained. 3) Open the circuit in which the current is to be measured, and connect test leads in series with the circuit. 4) Read the current value displayed on the LCD.
AUDIBLE CONTINUITY TEST 1) Connect the red test lead to the “VΩ” jack and the black test lead to the “COM” jack. 2) Set the range switch to the “ ” range. 3) Connect the test leads to the two terminals of the circuit to be tested. The resistance is less than about 40Ω, the built-in buzzer will sound. Battery & Fuse Replacement ” appears on the LCD, it indicates that the battery should be If “ replaced.
