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
