To di tingui h between the multiplier "Milli"(10-3)

and "Mega" (106), the abbreviation "M" for Milli and

"MA" for Mega are u ed.

One exception i the re i tance unit. There i no unit

for "Milliohm". The unit "MOHM" alway mean

MagaOhm!

For the mo t command that u e a

numeric value a parameter, the value

MIN and MAX can be pecified.

MIN de cribe the malle t po ible

value for a parameter (mo tly 0).

MAX de cribe the highe t po ible

value for a parameter.

Example: Set maximal current:

MIN and MAX mu t not be followed by a

The minimal and maximal value of a

numeric parameter can be determined

by query. To do o, a white pace a
