  • Page 3: General

    1. GENERAL This instrument is a high performance, 4½ digital bench multi-meter for measuring DC and AC voltage, DC & AC current, Resistance, Capacitance, Hz, hFE, Diodes and Continuity. The max. Voltage measuring can upto 1000V DC or AC peak value, resolution can be 10 V, and current measuring can upto 20A. It also has the function of polarity auto-change, backlight displaying and directly reading.

  • Page 10: Operation

    The meter is driven by 220V / 110V AC, when operating, connect the power socket to power plug firstly then 4. OPERATION turn on the power. Each meter is equipped with one pair of testleads as standard attachment, to insert the proper jack in front panel is banana plug, connect the pointed end of the testlead to the circuit under test.
  • Page 11 4.4 ACA : 1. Connect the black test lead to “COM” terminal and the red one to “mA” terminal (max.2A) or “20A” terminal. 2. Set the knob to ACA range, connect the test leads across to the circuit under measured, the polarity will be displayed with the voltage reading value.
  • Page 12 NOTE : 1. If the current under measure is unknown beforehand, start from the highest range and work down. 2. If only the MSD displays “ ”, it means overrange, should set to a higher range. 3. The max. Input current is 2A for “mA” and 20A for “20A”, large current will blow the fuse. Be careful when measuring 20A range, large current will make the circuit heat, even make the circuit damaged.

  • Page 13: Maintenance

    NOTE : 1. Do not input voltage or current signal at Capacitance range. 2. Release the capacitor completely to avoid damaging the meter. 3. It should take a few time to be stable when input at 200mF range. 4. The meter may not return to zero at capacitance range, it’s normal and has no effect on the accuracy. 4.9 TRIODE hFE MEASURING 1.
