4-4-L. Connecr the Blaclr test lead to the COM
terminal and the Red to the A terminal for
a maxirnum
of 2A. For a maxirmrm
of 20A, npve
the Red test lead to ttre 20A tenninal.
4-4-f. Set the function switch to the DC A range
to be used and open circuit in which
oJrrent is to be measured. Connect the test
leads in series witi the load urder

4-4-3. " - " sign for a negative current will
appear on the left side of the LCD.
Note: 1. See E voltage measurernent
Note 1, 2, 3.
2. The maximum inpt current is ZA or Z0A
deperdinE on the termina] used. Excessive
curent will blow the fuse, which must be
replaced. the Z0A range is not. protected
by the fuse. The fuse rating shoul"d not
be over 2A to prevent damage to the
internal" circuit.

4. In case of neasuring Z0A, continuous
measurement over 15 ninutes may cause
damageto the meter.
