lower edge into the groove at the bottom of the bezel. Push
it down against its spring until the top can be slid past at
the top of the bezel.
CRT Light Filter. The filter performs the same function
as the clear shield, and improves CRT viewing in brightly
lighted locations.
Viewing Hood. To install, attach the top first, inserting
the key into the groove at the top of the bezel.

1. Internal battery-powered operation should not be
continued for long periods after the LOW BA T T lamp
starts flashing. Damage to the NiCd batteries may
result. I f the batteries become sufficiently discharged',
the trace will disappear and the light will cease flash
ing. The battery should then be recharged to avoid
the possibility of individual cells becoming reverse-
charged. Operation can continue during recharging.
P6049 Probe. This probe includes a right angle adapter
which contains a compensation adjustment. See the explan
ation later in this section, or in the P6049 Probe manual.
Patch Cord. This cord can be used to connect a banana
jack to a BNC-female connector; for example, connecting
the Type 324 Oscilloscope CAL O U T jack to the T R IG OR
H O R IZ INPU T or the V E R T IN P U T connectors.
3 to 2-Wire Adapter (domestic orders only). Grounding
is not provided through the AC power source when the
adapter is in use. A separate grounding connection must be
used.
Panel Cover. A friction fit keeps this cover over the
front panel during storage or transporting. The cover can be
placed over the rear of the oscilloscope for storage when
the oscilloscope is in use. The recess in the cover accommo
dates the accessory pouch strap and should not be used as a
finger grip for cover removal.
Accessory Pouch. This unit grips on the handle pivots
and on the cover securing screw at the rear panel. It has
sufficient capacity to hold the standard accessories, with
the exception of the manuals and the Panel Cover.
2. Always operate within the oscilloscope's allowable
input values, which are as follows:
Po wer Source—A C
Power Source—DC
VERT INPUT
E X T TRIG OR
HO RIZ INPUT

Unless the Type 324 Oscilloscope is connected to a
common ground, its metallic parts will be elevated to
the signal potential to which it is connected. To in
sure personnel safety and dependable equipment
operation, connect a lead between oscilloscope
ground and equipment ground before connecting the
oscilloscope inputs to equipment test points. Do not
remove the ground lead until all other connections
are removed.
Strap Assembly. The strap is designed to be snapped
into place for transporting the oscilloscope. It can be used
to suspend the oscilloscope in front of or alongside the
operator during use. The handle can be extended between
the operator and the oscilloscope to obtain optimum view
ing positions.
FIRST TIM E OPERATION
General
This first time operation is designed to obtain a trace
and provide familiarization with the oscilloscope controls
and responses. A control setup chart is provided in Fig. 2-4.
It can be duplicated as a convenient method of recording
specific setups in conjunction with oscilloscope familiariza
tion and use.
