 The instrument won’t measure any AC value less than 1.5V.
Fig. 4: Use of instrument for DC/AC voltage measurement
1. Select the “ V ” position.
2. Insert the red lead into V/
 jack and the black lead into the COM jack. For ease of use,
attach the rubber holster and insert a test lead (see Fig. 3).
3. Connect the test leads to the circuit under test (see Fig. 4). The instrument
automatically selects “AC” or “DC”. For AC voltage measurements the frequency value
is shown on the secondary display.
4. The “-“ symbol indicates a negative DC voltage polarity.
5. The "O.L" symbol indicates a voltage higher than the full-scale capability of the
instrument
6. For HOLD and MAX/MIN/AVG/PK features refer to § 4.2.1 and § 4.2.3)
