Table 2-3 Multiple Displays By Function - Keithley 2002 User Manual

Some of the multiple displays are for multiple functions,
where different functions are measured sequentially from the
same set of test leads. The readings are shown simulta-
neously, such as:
• Top line shows a DC voltage measurement; bottom line
shows positive and negative peak spike measurements.
• Top line shows an AC RMS voltage reading; bottom
line shows an AC frequency measurement and a crest
factor calculation.
Also, the multiple displays can show a reading in a different
form, or give additional information about the reading, for
example:
• Top line shows a reading; bottom line shows a zero-
centered bar graph with adjustable limits.

Notes:
1. Multiple displays for calculated values and limits bar graph are not available for the frequency function.
2. The multiple display for adjacent channel readings is not available for the DC and AC current functions.
• Top line shows a frequency measurement; bottom line
To scroll through the multiple displays available for each
measurement function, repeatedly press and release the
NEXT DISPLAY key. The same action with the PREVious
DISPLAY key does a reverse scroll through the displays. To
return to the default reading display, just press and hold
either key.
Multiple displays that are specific to a particular function or
operation are discussed later in this section, such as the peak
spikes displays in DC voltage, and the calculations display in
math. (See Table 2-3 for paragraph references.) Displays that
are common to most of the measurement functions are dis-
cussed here.
