24V Heater Cartridge

[PlasmaFlow]

Is there a way to test a 24V Heater Cartridge?

What I mean is, if I use a VOM, What would be a correct resistance value for the cartridge?

I currently have a cartridge that even though I tune the PID for the heater, it never gets to temperature after the PID values are flashed again.

I also bought some extra cartridges and when I measure them the values are different even when they are supposed to be 24v 40w.

I also read that for using heater cartridges PID is better than Bang mode? Is this true?

Thanks!

~.8 ohms for a 30 watt.

~.6 ohms for a 40 watt.

The lead probe contact resistance will affect your reading a lot if you do not have a good connection when measuring.
