denotes the default units for the detector family in the given measurement
mode. Some display units are abbreviated. Table 6 lists displayed units
versus actual measurement units. Display units are limited to four characters
in order to provide for display engineering prefixes such as: p, n,
µ
, m and k
(pico, nano, micro, milli and kilo respectively).

2.3.15 STATS, Moving Statistics
The STATS key causes a list of statistical results from the stats buffer of the
display channel to be displayed in the message display area. The stats buffer
is a moving data window containing the most recent measurements to a depth
1
≤
N
≤
100. The default value is N = 10. Display occurs without disrupting
data acquisition or storage and results are continuously updated.
Press the STATS key to enter the stats display list. The first statistic displayed
will be the stats buffer depth N. Press the
, adjust keys to move through
the list. The following statistics are available: N, MAX, MIN, MAX-MIN, MEAN
and STD DEV.
When the STATS buffer depth, N, is displayed, it can be adjusted by pressing
ENTER and using the
, keys to set a new value for N. Press the ENTER
key to adopt the new value for N and escape the edit mode. The STATS buffer
is cleared whenever a new stats buffer depth N, or MODE or UNITS is estab-
lished. Press the STATS key a second time to exit the stats display mode.
2.3.16 R/S A(B), Run-Stop Channel A (or B)
The R/S A and R/S B run-stop keys provides front panel control over data
acquisition for each individual channel. When in SNGL measurement mode,
each R/S A(B) key press causes one reading to be taken on the respective
channel. In CONT measurement mode, each R/S A(B) key press toggles
continuous data acquisition on and off on the respective channel.
