NOTE

• The multimeter will automatically identify the voltage measurement

based on the following criteria:

• If AC V > 0.5 V or AC V ≥ the absolute of DC V, AC V will be selected.

• Otherwise, DC V will be selected.

• Press once to lock the initial signal identification (AC V or DC V).

Press again to exchange the AC and DC voltage indication on the

primary display. Pressing for the third time will restart the auto

identification of the signal. See Figure 2-7 to learn more.
