I was reading the datasheet of a digital multimeter (DMM) and I came across a resistance value terminated with 3/4, like so:

enter image description here

You can find it at the bottom of page 1-3 of the this document.

What does it mean?

    \$\begingroup\$ Ω2 and Ω4 refer to 2-wire and 4-wire resistance measurement techniques, respectively, while 100kΩ is just a resistance value. \$\endgroup\$

    \$\begingroup\$ @TobySpeight en.wikipedia.org/wiki/Mojibake (in short: character encoding messed-up during decoding/typesetting). Just for the people that didn't know the term since now (as I did) :-) \$\endgroup\$ Commented Dec 13, 2022 at 11:36

That's just a "typo" caused by an incorrect encoding specified for the characters/text of the datasheet, or the wrong font; something went wrong with the typesetting.

Just read "Ω" where it says "¾".
