For R
ISO
the limit is the minimum value. The limit range is from 1 kΩ to 15 TΩ.
The limit value is set using the and buttons. As the meter has many measurement sub-
ranges, an algorithm for rapid increase or decrease of values is implemented. When holding the value
key it changes very rapidly: first the hundreds, after 3 s tens, and after 3 s units etc. The limit setting is
circular. The resolution of the set limit is related to the sub-range.
To deactivate the limit (displayed symbol ---) press the button while in the 1 kΩ position or the
button while in the 15 TΩ position.
