Because some (not all) DMM's become unstable when looking
into inductive reactive loads. It's a problem to read some
meter movements, coils/inductors and transformer
winding resistance with many Digital Multi Meters.
-
Reading transformer windings can become dangerous
because the auto range circuit often keeps "hunting"
around for a value/position. Said hunting can induce
a rather interesting and dangerous voltage(s) from other
windings.
-
Even some of my better Fluke brand DMM's hunt
across inductive loads.

Why not just measure the resistance of the meter with the Fluke or other
Digital VOM? I have done it for years and never damaged a meter yet.
Agreed
do not use a Simpson 260
