    Do not operate the meter if the body of the meter or the test lead looks broken. Check the main function dial and make sure it is at the correct position before each measurement. When making current measurements ensure that the circuit is not “live” before opening it in order to connect the test leads.

  • Page 5 Don’t apply more than 500V DC or AC rms to the input, indication is possible at higher voltage but there is danger of damaging the internal circuit. Use extreme caution to avoid contact with high tension circuits when measuring high voltage. AC Voltage Measurement Connect the black test lead to the "COM"...
  • Page 6 Read the result from the LCD panel. Note: If the resistance value being measured exceeds the maximum value of the range selected, an over-range indication will be displayed (“1”), select a higher range. For resistance of approximately 1 megohm and above, the meter may take a few seconds to stabilize, this is normal for high resistance readings.

  • Page 7: Maintenance

    Caution: Dispose the used batteries according to the rules, which are defined by each community. Warning: If an explosion or fire hazard could occur through fitting a battery of the wrong type. Fuse replacement This meter is provided with a F0.5A/600V fuse to protect the resistance, Diode, Audible continuity test and the current measuring circuits which measure up to 200mA, with a F10A/600V fuse to protect the 10A range.
