Operating the 2000 Instrument
31
The amount by which the output has been deviated from the initial value is
shown in the display.
The level present when the “Adjust” mode was initiated is referred to as the
no-
minal
output in this document. Examples of display formats during “Adjust”
mode are shown below, with the increment digit underlined for clarity.
If the initial output level is:
–1.0 V
and no adjustment had taken place,
then the display shows:
1.0 0.0µV
If the initial output level is:
+10.0mV,
and
the output is adjusted to:
10.028mV,
then the display shows:
+10.02800m – 28µV.
The displayed deviation shows the amount the item being calibrated is in error.
Specifically it shows the opposite polarity to the amount the output level was
deviated, thus the
nominal
value is the addition of the actual output level and the
displayed deviation. The deviation always displays using the lowest possible mul-
tiplier, therefore:
A voltage deviation of up to
999uV
is displayed using the
µ
multiplier.
A voltage deviation of up to
999mV
is displayed using the
m
multiplier,
and
A voltage greater than
999mV
is displayed
without
a multiplier.
Current output levels and deviations are displayed similarly to the voltage output
levels and deviations shown above, with the exception that the deviation multip-
lier may be
p, n, µ
or
m
as required. Note that only
µ
and
m
are Units/Enter
keys.
An example of a simulated temperature deviation is shown below. Note that the
format is slightly different from a voltage or current output in that multipliers are
not used for either the deviation or the simulated temperature. The maximum
deviation possible is:
+/– 99.99ºC
or
ºF
. Any attempt to deviate a tempera-
ture beyond this limit will be ignored:
+1000.00+10.00ºC
Increasing or Decreasing Output Level
After the “Adjust” mode has been initiated, the output level or simulated tempera-
ture may be increased or decreased by using the
