SAFETY PRECAUTIONS
1. Beforeoperation. ground the instrument through a properly 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.

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 CONTINUOUS 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 disabled, DELAY is inserted between trigger and start of
conversionI.
13
-Readings on each channel consist of multiple cower*ions to fill the Running Average User Filter (30 conversions], or Running Average Internal Filter when active 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 settling 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.

CONTROLLER PROGRAMS
The following programs have been supplied as a simple aid
to the user and are not intended to suit specific needs. Each
program allows you to rend a device-dependent command
string to the instrument and obtain and display an instrument reading string.
31
IBM PC OR AT
(National Instruments GPIB-PC Interface)
The following program sends a command string from an
IBM PC or AT cdmpuw and displays the instrument reading
string on the ccmputer CRT. The computer must be equipped with the National lnstrumenrs GPIB-PC IEEE-488 in-
terface and the DOS 2.0 or 3.0 operating system. The GPIS-
PC software must be installed and configured as described in the instruction manual.
DIRECTIONS
1. From the front~panel, set the primary address of the Model
199 to 26.
2.With the power off, connect the Model 199 to the
IEEE-486 interface installed in the IBM computer.
3.Type in BASICA on the computer keyboard to get into the
IBM interpretive 8ASIC language.
4.~Place the interface software disk in the default drive, type
LOAD-DEW’, and press *he return key.
5.Add the lines below to the declaration file; also modify
the address in lines 1 and 2, as described in the GPl8PC instruction manual.
6.Run the program and type in the desired command string.
For example, to place the instrument in the ACV function and autorange, type in FlROX and press the return
key.
7.The instrument reading string will then appear on the
computer screen.
NAC”+0.000000E+O.
A typical example- is:

2. The Apple II terminates on commas in the data string.
To avoid ~problems, program the Model 199 for the BOG0
or BOG1 data format to eliminate commas.
Prompt for and enter

HP MODEL 85
The following program sends a command string to the
Model 199 from an HP-85 computer and displays the instrument reading string an the computer CRT. The campufer must be equipped with the HP82937 GPIB Interface
and an 110 ROM.
DIRECTIONS
1. Fmm the fmnt panel, set the primary address of the Model
199 to 26.
2.With the power off, connect the Model 199 to the
HP82937A GPIB interface installed in the HP-85
computer.
3. Enter the lines in the program below, using the END LlNE
key after each line.
4.Press the HP-85 RUN key and type in the desired com-
mand string et the command prompt. For example, to
place the instrument in ACV and autorange, type in FlROX
and press the END LINE key.
5.The instrument reading string will then appear on the CRT.
A typical dispJey is: NACV+O.OOOOOOE CO.

HP MODEL 9825A
Use the following program to send a command string to
the Model 199 from a Hewlett-Packard Model 9825A and
display the instrument reading string an the computer
printer. The computer must be equipped with the
HPg8034A HPIB interface and a 9872A extended I/O ROM.
DIRECTIONS
1. From the front~panel. set the primary address of the Model
199 to 26.
2.Wth the power off, connect the Model 199 to the
98034A HPlB interface installed in the 9825A.
3.Enter the lines in the .p~mgram below, using the STORE
key after each line Line numbers are automaticaliy assigned by the 9825A.
4.Press the 9825A RUN key and type in the desired command string at the command prompt. For example, to
place the instrument in ACV and autorange, type in FlROX
and press the CONT key.
5.The instrument reading string will then appear on the
computer ~p~rint out. A typjcal display is:

DEC LSI 11
The following program sends a command string to the
Model 199 from a DEC LSI 11 minicomputer and displays
the instrument reading string on the DEC CRT terminal. The
LSI 11 must be configured with 16K words of RAM and an
IBV 11 IEEE-488 interface The software must be configured
with the ,B software as well 8s FORTRAN and the RT 11
operating system.
DIRECTIONS
1. From the front panel program feature, set the primary
address of the Model 199 to 26.
2.With the power off, connect the Mode, 199 to the IBV
11 IEEE-466 interface cable.
3. Enter the program below, using the editor under RT 11
and the name IEEE.FOR.
4. Compile using the FORTRAN compiler as follows: FOR-
TRAN IEEE.
6. Link with the system and IB libraries as follows: LINK
,EEE,IBLIB.
B.Type~~RUN ,EEE and press the RETURN key.
7.The display will read “ENTER ADDRESS”.
B.Type in 26 and press the RETURN key.
g.The display will read “TEST SETUP”.
IO. Type in the desired command string and press the
RETURN key For example, to program the instrument
for ACV and autorange, type in FlROX and press
RETURN.
11. The instrument data string will appear on the computer
display. A typical display is: NACV+O.OOOOOOE+O.
