Maintenance
Rear Case
6–10
You will need a torque-limiting Torx T-15 screwdriver and pliers for this
procedure.
Refer to the exploded view diagram. (See page 8-10.)
Removal.
1. Remove the power button. (See page 6-9, Power Button.)
2. Place the oscilloscope face down on a soft surface such as an anti-static mat.
3. Remove the two ESD protection covers from the rear case to expose two
screws.
4. Remove the five screws located on the rear case. Tilt the handle to gain access
to the top two screws.
5. Lift the rear case off of the oscilloscope.
Installation.
1. Place the oscilloscope face down on a soft surface (such as an anti-static mat).
CAUTION.
Be careful not to pinch any wires or other parts between the front
and rear cases.
2. Place the rear case onto the assembled oscilloscope and verify that:
All of the edges align with the front case.
The Li-ION battery is vertical in the battery location.
The slots align near the USB connector and near the battery.
CAUTION.
Avoid cross-threading the screws that attach the rear case to the front
case. An easy way to avoid this is to slip the screw into the hole and, using slight
pressure, slowly rotate the screw counterclockwise until you feel the screw slip
into the screw threads. Then tighten the screw clockwise. A properly started screw
will exhibit very little resistance going in.
3. Install the five screws in the rear case. Tilt the handle to access the top two
holes.
4. Install the two ESD protection covers.
5. Install the power button. (See page 6-9, Power Button.)
