Model 2000 Digital Multimeter Quick Start Guide
Setting limits
— To set limits (absolute values), press SHIFT and then LIMITS to display the high
limit. Use the
,
,
▲
and
▼
keys to enter the desired value, and press ENTER. Enter the low
limit value and again press ENTER.
Enabling limits
— Press SHIFT and then ON/OFF to display the beeper status. Use the
▲
and
▼
keys to change the beeper status (NEVER, OUTSIDE or INSIDE) and press ENTER to enable
limits. Pressing SHIFT and then ON/OFF a second time disables limit operations.
Reading hold
With this feature, an audible beep is sounded when a valid, settled reading is acquired. A valid
reading is determined by the specified window and count.
1.
Press SHIFT and then HOLD. Select a window percentage and enter a count.
2.
Apply the test probes to the signal and wait for the beeper to sound to indicate a valid read-
ing.
3.
Remove the hold condition by lifting the probes.
Pressing SHIFT and then HOLD a second time disables Hold.
Triggers
Factory defaults place the instrument in a continuous (immediate) measurement mode. The
instrument can be placed in an external trigger mode where a programmed event is required to
cause a measurement (device action).
The instrument is placed in the external trigger mode by pressing the EXT TRIG key. In this mode,
a device action (measurement) will occur when the TRIG key is pressed, a bus trigger (*TRG or
GET) is received, or an input trigger via the TRIGGER LINK connector is received. After the device
action (measurement), an output trigger occurs and is available at the TRIGGER LINK connector.
Refer to the User’s Manual for details on using the trigger link. Pressing EXT TRIG a second time
returns the instrument to continuous operation.
Delay
— A programmable delay before the device action (measurement) occurs is available. It
can be set manually or an auto delay can be used. To set a delay, press SHIFT and then DELAY.
Use the
▲
and
▼
keys to select AUTO or MANual. If MANual is chosen, enter the duration of the
delay and press ENTER. The AUTO delay times are listed in Table 3-2 of the User’s Manual.
Scan operations
The Model 2000 can be used with an internal scanner card (Model 2000 SCAN or 2001-TCSCAN),
or with external scanner cards installed in a switching mainframe (i.e. Model 7001 and 7002).
Step/Scan configuration
— A “walk-through” menu is provided to configure stepping or scanning.
The main menu is accessed by pressing SHIFT and then CONFIG. Use the
,
,
▲
,
▼
and
ENTER keys to select scan type (INTernal or EXTernal), first channel in the scan (MINimum
CHANnel), last channel in the scan (MAXimum CHANnel), time between scans, and reading count
(RDG CNT).
and
keys
— These keys can be used to manually scan through channels on the internal
scanner card. Press
to manually increment channels or
to manually decrement channels.
Hold down either key to scan continuously.
OPEN and CLOSE keys
— Use these keys to open and close channels on the internal scanner
card. After pressing CLOSE, use the
,
,
▲
and
▼
keys to display the desired channel (1 to 10)
and press ENTER. Selecting a different channel will cause the previously closed channel to open.
For the ¾4 function, CLOSE will close the selected channel and the paired channel. Paired
channels for the Model 2000 SCAN are 1&6, 2&7, 3&8, 4&9, and 5&10. Channel pairs are similar
for the Model 2001-TCSCAN except that channels 1&6 are not paired.
