@zeeglen, I have no idea why they would be wax covered. I was hoping someone would give a valid explanation in the comments. I'm guessing it is shielding of some type, but is wax paper that effective?

I'm not sure what you're referring to, but now I'm really curious!

I can understand your confusion. This is not a typical thing to see. Usually, only capacitors would carry that waxy coating. however, in this case, those are resistors. You can see it in the schematic as well as just figure it out by looking at what the mode selector that they are attached to does. it changes the resistance!

I think it's strange that it doesn't have a mirror. I thought even the cheap ones had a mirror to deal with parallax.

@ Caleb - Why wax sleeves over the resistors?  Might this be intended as an indication of overheating if a user applies a higher-than-rated voltage, or any voltage with the function switch set to "ohms"?

@ molear - looking at the schematic and parts list these are 1% resistors, there are only 3 wax paper caps listed.

Waxed paper parts

The parts in waxed paper are NOT resistors.  Those would be capacitors, and I would be very careful using that device.  The old paper and wax capacitors can go bad.  I've had one explode and blast scraps of burning paper around the room.

IoT Network Shoot Out
July 16, 1pm EDT Thursday

Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion. Join in and ask his guests questions.
