Are these resistance readings ok?

Hi folks,

I've measured the resistance between the connections named in the manual. I have to mention I'm doing this with a cheapo multimeter but I'm getting 125KΩ for between the thermistor wires, instead of 100KΩ mentioned. Is this the multimeter, acting all unprofessional or is this ok? Also maybe these values are out of order?:

Extruder heater: 6,5Ω (manual: 5,8Ω)
Bed heater: 1,9Ω (manual: 1,2Ω)
Motors: around 2,5Ω (manual: 1,9Ω)

Looks like your meter leads add about 0.6R.

125K for the thermistor is most likely because your room is colder than 25C.

Hi Chris,

Yep definitaly below 25 C. More like 20. So they rise that fast then. Thanks for pointing out the consistency in addition of the values due to the multimeter. When I hold the pins together I indeed read 0,6 or 0,7 ohm.
