Reassembling the Meter

Before reassembling the Meter, read the How to Retain the IP67 Rating
section first.
To reassemble the Meter, perform the disassembly steps in reverse order.

How to Retain the IP67 Rating

The following items identify parts of the Meter that can compromise the IP67 rating by
leaking if assembly instructions are not followed carefully.
1. Knob: The knob has an overmolded seal that fits tight against the top case. This area
must be lubed and the lube must be spread evenly around the seal area.
2. E-clip: Make sure it is installed correctly.
3. Keypad: The keypad must be seated correctly and all six board screws tightened to 6
in-lbs torque.
4. Bottom case gasket: The gasket must be installed so that the gasket does not have any
twists, bends, waves, etc. The gasket must be completely flat in the bottom case
groove. This can be accomplished by using a modified top case to push the gasket
into position.
5. Battery door gasket: Place over battery compartment walls and push each corner
down as far as they will go. Install battery door screws with 6 in-lbs torque.
6. Fuse access door: Place onto bottom case and wiggle it to make sure it is fully seated.
Install the battery door screws with 6 in-lbs torque.
7. Case screw o-ring: Torque case screws to 12 in-lbs torque. Verify that the o-rings are
not sticking out of the sides of the screw head.
If you want to ensure your Meter meets the IP67 rating, return the Meter to
a qualified Fluke Service center.
