Reassembling the Meter

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 overmold 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 correctly seated, 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.
