2.2.3 Front panel display
Normal displays
In the normal display mode, the front panel of the Model
2001 shows the following:
• Top line  Readings, units, and channel number if
scanning. Where needed for clarification, the type of
measurement.
• Bottom line  Range, if fixed; ACV and ACI coupling;
frequency coupling and terminals; temperature sensor.
Most readings have from 3.5 to 7.5 digits of resolution. For
example, an AC voltage measurement (RMS type), at 5.5
digits on the 200VAC range would be displayed as follows:
+000.000 VAC RMS
Range: 200 VAC Coupling: AC
With a math operation enabled (percent or mX+b), the
reading could be expressed in scientific notation, such as:
+5.0000e+03 VAC %
Range: 200 VAC Coupling: AC
Multiple displays
The mode called multiple display is accessed from the
normal display by pressing the NEXT or PREVious
DISPLAY keys. Each measurement function has its own set
of multiple displays.
In the multiple display mode, the Model 2001 can show the
readings of up to three separate measurements. For example,
in the DC voltage function, one of the multiple displays
shows DC volts, AC ripple voltage, and ripple frequency:
+00.00000 VDC
+00.0000 VAC +000.00 Hz
Or, a multiple display can show a bar graph, such as:
+12.00000 VDC
0|=====|=====|== | |+20V
Multiple displays are described in detail in Section 3. The set
for the DC voltage function is also shown in Table 2-1.
INFO displays
There are context-sensitive information message displays for
most front panel operations. The explanatory information is
toggled on and off with the INFO key. For example, the
INFO message for one of the DCV multiple displays is:
INFO: VDC, VAC, Hz
Shows DC value, AC ripple, and
the ripple frequency.
where the blinking and characters signify that the
front panel cursor keys must be used to view the complete
bottom line.
Configuration menu displays
Each measurement function is individually configured by
pressing CONFIG followed by the function key. In addition,
operations that affect all measurement functions, such as
triggers, data storage, and limits, are also configured by
pressing CONFIG followed by the operation key.
The top level of the configuration menu for DC voltage is
accessed by pressing the CONFIG key, and then the DCV
key. The resulting display reads:
CONFIGURE DCV
SPEED FILTER RESOLUTION
In some cases, menu selections branch off to further define
the options, such as the following for the SPEED option:
DCV MEASUREMENT SPEED
NORMAL FAST MEDIUM HIACCURACY
SET-SPEED-EXACTLY SET-BY-RSLN
Guidelines for navigating the front panel menus are
summarized in Table 2-2.
