MEASURING VOLTAGE
1. Insert the test leads in the jacks.
2. To select a voltage function, put the slide-switch in the middle position. See
Figure 3.
To toggle between dc and ac, press [g].
3. Touch the probes to the test points, and read the display. The meter beeps an
Overload Alert™ when OL (overload) is displayed.
In manual range, you can toggle the meter between a high or low input impedance
mode by moving the slide-switch between the voltage and continuity/ohms positions.
(See “i AND HOW TO USE IT”.) In the continuity/ohms position, the input
impedance of the meter is 2 kΩ, and LoZ is displayed to indicate that the meter is in
the low input impedance mode. In the volts position, the input impedance is 5 MΩ in ac
and 10 MΩ in dc.
