DC Voltage Measurement

Capacitance Measurement

  1. Press Ω button and respectively plug in the red and black test leadss into "VΩHz" and "COM".
  2. After the instrument is turned on, triggering the Ω button Is the automatic identification measurement of resistance, diode, buzzer and capacitor. Under the mode of automatic identification, such bottoms as "RANGE", "MAX/MIN", "HOLD" do not play the controlling functions; In case the capacitor being measured is smaller than 0.5nF and bigger than 600μF, please trigger the "SELECT" button, please Trigger the non-automatic identification automatic capacitance measurement mode, and at this time, such buttons as "MAX/MIN", "HOLD", "RANGE" play the functions. )When the mains current is mistakenly fed into the capacitor mode, the circuit may have automatic protection and it will not damage the meter.)

Caution:

  1. When measuring the capacity, all the powers within the tested circuits must be disconnected and the capacitance shall be sufficiently discharged; when measuring big capacitors, it takes a longer time.

Capacitance Measurement

Electric Field Measurement

  1. After triggering the "AC/DC/EF" button, trigger "SELECT" button in cycle, until the LCD displays "EF", at this time, the meter enters the electric field measurement mode.
  2. Put the area of the meter near the arrow near the measured object.
  3. The strength of the electric field is judged by the number of “—” displayed on the LCD display, and based on the interval and continuous beeping sound produced by the buzzer of the EF strength.

Caution:

  1. It is prohibited to input any voltage at any input ports.

Electric Field Measurement

Resistance Measurement

  1. Trigger Ω button, and respectively plug the red and black test leads into the holes of "VΩHz" and "COM"
  2. After the instrument is started, triggering Ω button is the automatic identification measurement of resistor, diode, buzzer and capacitor. Under the mode of automatic identification such buttons of "RANGE", "MAX/MIN", "HOLD" do not play the controlling functions, and in case the measurement is bigger than 1MΩ, only when the "SELECT" button is triggered can the automatic range resistance mode can be measured, and at this time "RANGE", "MAX/MIN", "HOLD" play the controlling functions

Caution:

  1. When measuring the capacity, all the powers within the tested circuits must be disconnected and the capacitance shall be sufficiently discharged When measuring the resistance, any occurrence of voltage may Lead to inaccurate readings, and if the 250V protection voltage is exceeded, it may damage the meter or threaten the safety of the user.
  2. When the range of 600Ω is in use, first sort-circuit the test leadss and measure the resistance of the lead wires and then deduct it in the actual measurement.

Resistance Measurement

Diode and On-and-Off Test

  1. Press Ω button and respectively plug the red and black pens into "VΩHz" and "COM".
  2. After the instrument is started, triggering Ω button is the automatic identification measurement of resistance, diode, buzzer and capacitance. Under the mode of automatic identification such buttons of "RANGE", "MAX/MIN", "HOLD" do not play the controlling functions, trigger "SELECT" to select the diode or buzzer measurement, at this time such buttons as "MAX/MIN". "HOLD" play the controlling functions.
  3. Connect the red test leads to the positive of the diode, the black test leads to the negative of the diode.

Caution:

  1. In case the diode is open circuit or the polarities are connected reversely, "OL" will be displayed on the screen.
  2. When checking the diode, all the powers within the tested circuits must be disconnected and the capacitance shall be sufficiently discharged.
