SAFETY PRECAUTIONS
1.Beforeoperation. ground the instrument through a proper-
ly earth grounded power receptacle.
Z&fore servicing. disconnect the instrument from the
power line and all other equipment, and consult the Model
199 Instruction MamaI.
3. Do not touch any terminals while the instrument is turned
on or connected to any other test equipment.
4.Do not exceed the maximum input levels es stated in the
specifications for the instrument bee the Model 199 In-
struction Manuall.
5. Use the special precautions listed in paragraph 2.6 of the
Model 199 Instruction Manual when testing high-energy
circuits.

Determining Scannlng Interval
l Scanning without selecting interval
-Program ,NTER”AL SELECT to OFF.
-Interval is s175msec. depending on other selected
parameters.
-INTERVAL OVERRUN message will not be displayed.
l Minimum Interval Time Calculation
--Interval time is the sum of:
1. (conversions per channel1 x Iconversion time1
2. Programmed DELAY time per channel
3. Break-before-make time l17msecl
4. Auto range time (if usedl
-In STEP mode, calculated time above is the INTERVAL
setting.
-In SCAN mode, (sum of l-41 x (number channels
scanned) is the minimum interval setting.
l When using the scanner with STEP or SCAN switching,
the DMM will take readings on each channel as if it were
in the one-shot mode whether programmed to CON-
TINUOUS or ONE SHOT:
-Conversions are automatically synchronized to chan-
nel closures. Channels will not close in the middle of
conversions.
-Any programmed DELAY is inserted between channel
closure and start of conversion (with scanner disabl-
ed, DELAY is inserted between trigger and start of
conversionI.
13
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

-Readings on each channel consist of multiple cower-
*ions to fill the Running Average User Filter (30 con-
versions], or Running Average Internal Filter when ac-
tive 15%d only, varies by range and function; see
me”“al,.
l Scanner switching is break-before-make. The time re-
quired to change channels is approximately li’msec,
which~includes break-before-make relay time settling time
* When using the scanner with ACV or ACA, a DELAYtime
must be programmed to acccmcdate AC converter set-
tling time (typically >lsecl. See Model 199
specifications.
l The scanner operates with the set of instrument
parameters programmed prior to start of scanning. Chang-
ing any of these parameters, range function, filter, etc.
during scanning will restart the scanner at channel 1. Use
autorange if range changes are required while scanning.
Example of Fast Scanning
1. Select 3” DC range and function, 4%.digit resolution,
FLTR off.
2. Program ONE SHOT trigger.
3. Select SCAN mode.
4. Select SCANNER “8” to set limit to 8.
S.&e TRIGGER to initiate a scan of the set of eight
channels.
