right angle filler plate bracket on the right front
side of the Meter, keeping the smooth face with
two holes of the bracket facing the front as shown
in Figure 2.
2. With the tray flat on a desk with the rack screw
ears toward you, place the Meter so the left side
of the front frame is against the left wall of the
tray.
3. Attach the Meter to the tray by inserting one #832 x ½" panhead screw through the left-hand
forward holes in the tray and into the side of the
Meter as shown in Figure 2.
6. Install the 9½" painted filler panel to the right
front of the tray by inserting the attached screws
through the holes in the right-angle bracket and
locking it in with lock washers and lock nuts as
shown in Figure 2.
7. Install the assembled rack mount kit in the rack
using the four rack screws with the painted 1"
wide plate under the screws on the left-hand side
of the rack mount tray as shown in Figure 2.
8. Complete the installation by installing the Meter’s
