Step 5



Enable the digital filter

If the filter is not on, press FILTER to enable the digital filter.

The type of filter and number of readings selected is

displayed momentarily, for example:

Filter Enabled

Digital = AVG(10)

The reading should now be less noisy. The digital filter can

be disabled by pressing the FILTER key again.

Step 6



View the multiple displays

Each measurement function has a series of front panel

displays. The displays are accessed with the NEXT

DISPLAY and PREV DISPLAY keys.

1. From the normal display of DC voltage, press the NEXT

DISPLAY key once to also view AC voltage and

frequency measurements of the signal, for example:

+000.0000 mVDC

+000.000 mVAC +000.00 Hz

2. Return to the normal DCV display by pressing PREV

DISPLAY, or view the remaining DCV displays by

pressing NEXT DISPLAY, which wraps around to the

normal display. The DC voltage multiple displays were

shown in Table 2-1.

Pressing and holding either the NEXT

DISPLAY or PREV DISPLAY key returns

to the normal display.

2.5.2 Storing DC voltage readings example

This example assumes the Model 2001 is reset to its bench

defaults, as outlined in paragraph 2.4. It also assumes the

instrument is connected to a DC voltage source, and the front

panel displays on-scale readings.

Step 1



Configure for high speed measurements

To make high speed readings of a voltage source, change the

configuration of DC voltage measurements, as follows:

1. Press CONFIG-DCV to view the DCV configuration

menu:

CONFIGURE DCV

SPEED FILTER RESOLUTION

2. Select SPEED from the menu, then press ENTER. The

multimeter displays the following menu:

DCV MEASUREMENT SPEED

NORMAL FAST MEDIUM HIACCURACY

SET-SPEED-EXACTLY SET-BY-RSLN

3. Using the cursor keys, select the FAST option, then

press ENTER. Since the resolution is set to AUTO,

where it defaults to a value appropriate for the speed, it

will be set to 4.5d automatically.

4. Press EXIT to return to the normal display.

Step 2



Store the readings

To store readings in the instrument’s data storage buffer,

perform the following:

1. Press the STORE key. The following message is

displayed:

STORE 00100 READINGS

Use , , , , ENTER,EXIT, or INFO

2. The factory default number of readings to store is 100.

Use the cursor and RANGE keys to make changes. The

maximum possible number of readings depends on the

following:

• The data group selected for storage (full or com-

pact). This is selected under the CONFIG DATA

STORE menu.

• The memory option (STD, MEM1, or MEM2).

3. Press ENTER to start storing readings. The asterisk

annunciator lights to indicate a data storage operation.

The bottom line of the display counts up the data storage

points.

Step 3



Recall the readings

To recall the stored readings, perform the following:

1. Press RECALL to view the readings. The following

message is displayed with the cursor on the least

significant digit of the reading number:

+00.00000 VDC

Rdg#+00000 @Time=+000.000000 sec

2. Use the RANGE  and  keys to increment and

decrement the reading number and scroll through the

buffer.

3. The NEXT and PREV DISPLAY keys can be used

while recalling readings to access additional data, as

shown in Table 2-4.
