PPA5xx/15xx communications manual
2-24
Load a calibration string.
When calibrated, the instrument stores a
text string which can be read on the front
panel (press SYS and LEFT). This shows
the date of calibration. Users who
subsequently verify the accuracy in their
own calibration facilities can enter an
alternative string with the new date. The
original string is not overwritten but the
alternative string is displayed instead.
string is any sequence of printable alpha
numeric characters. Use the underscore
character to add a space between words.
CALSTR without a string argument clears
the previously stored string.
As all white space is stripped from any
communications string, the underscore
character (ASCII 95 or 0x5F) must be
used to space out the words. Underscore
is shown as a space on the screen.
