MODE Button To select Diode/Continuity, DC/AC Hz/%Duty HOLD Button The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or to exit the HOLD function. RELATIVE Button The relative measurement feature allows you to make measurements relative to a stored reference value. -
Page 12: Dc Voltage Measurements
DC Voltage Measurements CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. 1. Set the function switch to the position. 2. Press MODE (if required) so DC appears on the display. 3. -
Page 13: Dc Current Measurements
DC Current Measurements CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. 1. Insert the black test lead banana plug into the negative COM jack. 2. -
Page 14: Ac Current Measurements
AC Current Measurements WARNING: To avoid electric shock, do not measure AC current on any circuit whose voltage exceeds 250V AC. CAUTION: Do not make current measurements on the 10A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. -
