2. Current control mode (<S> for static, <D> for
dynamic).
3. Entry field for setting the desired hold limit. Recalls
the default hold limit or the last custom hold limit set
for the currently active range.
Enter the desired hold limit. The next display is:
1. Current reference transducer (<H> for high, <L> for
Lo) and range (<1>, <2> or <3>).
2. Current control mode (<S> for static, <D> for
dynamic).
3. Entry field for setting the desired stability limit.
Recalls the default stability limit or the last custom
