4.6 Current measurements

These are made in series with the test circuit. All the current to be
measured flows through the multimeter.
WARNING
Do not attempt to measure currents in high energy circuits
capable of delivering greater than 600V. Since the fuse is
rated at 600V damage or injury could occur. The 20A
input terminal is protected by a 20A/600V high energy,
fast blow fuse. The mA input terminal is protected by a
500mA/500V fast blow fuse.
Do not exceed the limits of each current input terminal. This is 20A
(maximum time limit of 30 seconds for currents greater than 10A) for
the 20A terminal and 400mA for the mA terminal.
All current rages are fused. If a current greater than 20A on the 20A
range or greater than 500mA on all other ranges flows, the fuse will
blow causing an open circuit between the current measuring
terminals.
1. Insert the BLACK test lead in the COM input terminal.
2. For measuring currents less than 400mA, connect the RED
test lead to the mA input terminal. For measuring currents
between 400mA and 20A connect the RED test lead to the
20A terminal.
3. Select the desired AC current range or DC current range.
NOTE: If the 20A range is selected then the 20A input terminal must
be selected in step 2. If the μA, mA ranges is selected the
mA input terminal must be selected in step 2.
