A minus sign on the left hand side of the LCD will appear if the
leads are connected the other way round.
CURRENT MEASUREMENTS
These are made in series with the test circuit. All the current to be mea-
sured flows through the multimeter.
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.
