4.1 Household Batteries
Set the function/range switch to 10V DC to
test household 1.5 volt through 9 volt batteries.
Touch the red (+) test lead to the (+) terminal
and the black (-) test lead to the (-) terminal
of the battery. Read the 0-10 scale to
determine the condition of the battery.
5. DC Milliamp Measurement
1) Fully seat the test leads in the correct input
jacks, (-) black lead, (+) red lead.
2) Set the function/range switch to the
appropriate DCmA setting.
3) Touch the test leads to the circuit in series (in
line with the circuit) so that the circuit current
passes through the multimeter in order to
make the measurement. If the needle indicator
deflects to the left, reverse the test leads.

Common DC Milliamperage
Measurements
It is important to point out that milliamps can
also be expressed as thousandths of an
Ampere; therefore 150 milliamps is 150
thousandths of one Amp. The 150mA function
of your multimeter is commonly used by
electronics repair technicians and hobbyists to
troubleshoot various low voltage circuits.
Although not normally used for electrical
troubleshooting around the home, this function
can be used to measure the milliamperage
draw of household items such as flashlights,
and other battery operated devices that do not
draw more than 150 mA. In fig. 2 the red (+)
test lead is hooked up to the (+) terminal of the
lantern battery while the black (-) test lead is
hooked up to the bulb. The meter will indicate
the milliamperage draw when the flashlight
switch is thrown in the ON position.
Do not apply voltage to the
test leads while the meter is set in the
milliamp range. See #8
For Your Safety.
6. AC Voltage Measurement
1) Fully seat the test leads in the correct input
jacks (-) black lead, (+) red lead.
2) Set the function/range switch to the
