The display then returns to displaying the selected output level and mode.
The output terminals will either be open circuit–if “Standby” was selected, or
at the requested output level–if “Operate” was selected.
Caution:
Prior to selecting the “Operate”
mode, check the displayed output lev-
el. If the connected external circuitry is incompatible with the selected output
level, then this circuitry could be damaged when changing to “Operate”
mode.
Numeric Data Entry
At various places in the following procedures, the user is requested to provide
numeric data input to the instrument, this paragraph describes the actions re-
quired.
Numeric data entry is initiated by pressing a numeric key on the front panel (i.e.,
the digit keys 0 through 9 or the decimal point key). The display then shows the
entered numeric in the left-most character position of the display and the remain-
ing portions of the display will be blank. The cursor will automatically move to
under next possible character entry point, showing the position into which the
next key press will be placed. (Leading zeroes, prior to a decimal point or prior to
a non-zero numeric, are ignored.)
Up to 7 digits plus a decimal point may be entered, entries beyond this are ig-
nored. If no decimal point has been pressed, it is assumed to be following the last
digit pressed (e.g., an entry of
124
is equivalent to an entry of
124.0
).
The multiplier keys (m and u) may be used during numeric entries. Thus entries
of
0.001
and
1m
are equivalent. Note that certain entries must use a multiplier,
e.g., if an entry of
0.00000012
is desired, then this must be entered as
0.12µ
.
If an error is made during numeric entry then several options exist for correcting
the data, prior to terminating the entry. The steps are the same for a new entry or
during a prompted entry.
To correct a data entry error:
1.
Press the CLR
key. This initializes the entry point either to a blank area or the
previous data.
