You can also use any of the ohm scales, especially the lowest
one, to measure ohms. If the heater is good, it will show zero or
close to it.


OOops. If the heater is good, it will show a low value, but not zero.

With analog meters, where the ohmmeter part has to be "zeroed", and
where different scales zero maybe a bit differently, I got used to
thinking, in places where the actual value wasn't critical, where I
was using the meter to decide if there was continuity or not, of
anything close to zero as zero.

If the heater is bad, it will not change from when the
probes are not touching anything. The reading will be blank, or
dashes, or something like that. You can verify the meter is working
by connecting its two probes right together and it should say zero or
very close to zero.
