Position the conductor within the jaws at the intersection of
the indicated marks as much as possible (Figure 1) in order
to meet this Meter’s accuracy specifications.
If the conductor is positioned elsewhere within the jaws, the
maximum additional error resulted is 1.5 percent.

5. How to Use this Meter
5.1 Battery Replacement
This Meter is powered by a single 9V battery (NEDA Type
1604A, 6LF22, or 006p). To guarantee the specified battery
life, alkaline or other long-life batteries are recommended.
If the low-battery indicator on the dig
i
tal display will be
d
i
s
played, replace the battery by using the following
procedure referring to Figure 2.
1. Unclamp this Meter from any conductor, and turn it off by
pressing the ON OFF pushbutton.
2. Place this Meter fa
c
e do
w
n on a non abrasive surface
and completely loosen the three rear panel screws with
a Phillips-head screwdriver.
