  • Page 12: Warning And Cautions

    Making Basic Measurements Preparation and Caution Before Measurement : Observe the rules of Warnings Cautions When connecting the test leads to the DUT (Device Under Test) connect the common (COM) test lead before connect- ing the live lead ; when removing the test leads removing the test live lead before removing the common test lead.
  • Page 13 Measuring AC/DC Voltage And Frequency...
  • Page 14 Note – When measuring voltage, the Meter acts like a 10MΩ impedance in parallel with the circuit under test. This loading effect of the 10MΩof the Meter can cause measurement errors, loading efffect error, Especially in high impedance cir- cuits. For example : A 1.1M impedance circuit will cause a –10% measuring error.
  • Page 15 Measuring Resistance  Caution To avoid possible damage to the Meter or to the equip- ment under test, disconnect circuit power and discharge all high-voltage capacitors before measuring resistance. Note – The Meter provides a open voltage ≦–1.5V to the circuit under test that cause the diode, transistor junction to conduct so it is batter to disconnect the resistance from the circuit to get a correct measurement.

  • Page 16: Testing For Diode And Continuity

    Testing for Diode and Continuity Diode : Bad! Good! Good! Continuity :  Caution For in-circuit test, turns circuit power off and Discharge the high-voltage capacitors through an appropriate resistance load.
  • Page 17 Note – Use the diode test to check the semiconductor junction is good or bad. The Meter sends a current through the semiconductor junction to measures the voltage drop across the junction. A good junction drops between 0.4 V to 0.9 V. Measuring DC mA, AC mA, DC A, AC A Current And Frequency ...
  • Page 18  Caution To avoid possible damage to the Meter or to the equip- ment under test, check the Meter’s fuses before measur- ing current. Use the proper terminals, function, and range for your measurement. Never place the probes across (in parallel with) any circuit or component when the leads are plugged into the current terminals.
  • Page 19 Making Basic Measurements Measuring Hz / RPM  Note – Connect the red test lead to the “ VΩHz ” terminal and the other (black) test lead to the “COM” terminal. Set the rotary function selector to “Hz RPM” position to meas- ure the frequency or RPM with the blue switch.
