parameters may be en-

disabled with [On

]. Each of these parameters has an
additional indicator to the right of the descriptor to indicate the
on

The

values are display-
only. All the other values can be changed using the [ ] but-
tons; the digit selected for adjustment is indicated by its flash-
ing brightness. Change the digit selection while
Shift
is high-
lighted ([

•
There are two formats for the numeric display: Exponential,
and fixed decimal. The format used for a particular param-
eter depends on its range. Parameters
P
,
I
,
D
and
SP Ramp
(rate) vary by several orders of magnitude and are therefore
displayed in exponential format, while all other parameters
range from
−
10 V to
+
10 V and are displayed in fixed decimal
format.
•
For exponential format, the mantissa may be changed using the
up
/
down arrow buttons. The active digit may be selected using
the left
/
right buttons (
=
shift, followed by up
/
down button).
