No it will display what ever is been drawn, so no you don't times/divide the reading. so if it draws less than 1 amp the meter will display .200 say or anything over 1 amp it will dispaly 1.5 say. The same goes for the resistance reading only if your set to 2K the and put say 200ohm on there is will read 0.200 and if to put 1K on the it should read 0.999 tp 1.100K

I only times it by 8 to show you, All you need to do is times the reading by the number of solenoids you are running, so if you got 4 then times it by 4, It would pay for you to allow and extra .5 to 1Amp say for all the stuff you will have runnig of the rectifier
