7.4 Checking Amperage
The Multimeter can be used to check amperages under 10 amps in AC or DC current.
When checking the amperage of the electric hose
always use a clamp-on amp meter (See Figure
7.2 Clamp – On Amp Meter/Multimeter ) . The amperage in the hose can reach as high as 35
amps.
Clamp the meter around one wire at a time. Remember most clamp-on meters do not work on DC
current.
