  • Page 4: Safety Information

    1. SAFETY INFORMATION This multimeter has been designed according to IEC-1010 concerning electronic measuring instruments with an overvoltage category (CAT II) and pollution 2. Follow all safety and operating instructions to ensure that the meter is used safely and is kept in good operating condition.

  • Page 5: Usage

    1.2 USAGE • Never exceed the protection limit values indicated in specifications for each range of measurement. • When the meter is linked to a measurement circuit, do not touch unused terminals. • When the value scale to be measured is unknown beforehand, set the range selector at the highest position.

  • Page 6: Symbols

    1.3 SYMBOLS Important safety information, refer to the operating manual. Dangerous voltage may be present. Earth ground. Double insulation (Protection class II).

  • Page 7: Maintenance

    1.4 MAINTENANCE • Before opening the meter, always disconnect test leads from all sources of electric current. • For continue protection against fire, replace fuse only with the specified voltage and current ratings: F1: F 500mA/250V F2: F 10A/250A • If any faults or abnormalities are observed, the meter cannot be used and it has to be checked out. •...

  • Page 14: Operating Instructions

    3. OPERATING INSTRUCTIONS 3.1 MEASURING VOLTAGE 1. Connect the black test to the COM jack and the red test lead to the V/Ω jack. 2. Set the function switch at V or V ~ range to be used and connect test leads across the source or load under measurement.

  • Page 15: Measuring Resistance

    3. Connect test leads in series with the load in which the current is to be measured. 4. Read LCD display. The polarity of red lead connection will be indicated when making a DC measurement. 3.3 MEASURING RESISTANCE 1. Connect the black test lead to the COM jack and the red test lead to the V/Ω jack. (NOTE: The polarity of the red lead connection is positive “+”) 2.

  • Page 16: Continuity Test

    3. When checking in-circuit resistance, be sure the circuit under test has all power removed and all capacitors fully discharged. 3.4 CONTINUITY TEST 1. Connect the black test lead to the COM jack and the red test lead to the V/Ω jack. (NOTE: The polarity of red lead connection is positive “+”) 2.

  • Page 17: Testing Transistors

    3. Connect the red lead to the anode of the diode to be tested and the black lead to the cathode. Read LCD display to get the forward voltage drop of the diode under testing. 3.6 TESTING TRANSISTORS 1. Set the function switch at hFE position. 2.
