Input String Examples

Computer Interface Commands and Operation

instances, a terminator is automatically transmitted by the host at the end of the command string, for example, commands entered in BASIC.

Below are four input string examples. Example 1 - Select function for channel 1 as ohms, 30-k range, 2-wire connection.

FUNC 1, OHMS, 3, 2 <CR/LF>

Example 2 - Select function for channel 12 as temperature, using K-type thermocouple.

FUNC 12, TEMP, K <CR/LF>

Example 3 - Select function for channel 7 as temperature, using platinum RTD, 2-wire connection -and- set a new R0 [0 as in zero] value on the same channel of 101.22.

FUNC 7, TEMP, PT, 2;RTD_R0 7, 101.22 <CR/LF>

Example 4 - Set the interval between scans to 10 minutes -and- start scanning -and- return the most recent measurement values for all scanned channels.

INTVL 0, 10, 0;SCAN 1;LAST? <CR/LF>

Sending Numeric Values to the Instrument

Numeric values can be sent to the instrument as integers, real numbers, or real numbers with exponents, as shown in the following examples:

+12345Sends the signed integer+12345

123.45Sends the real number123.45

1.2345E+2Sends the number -1.2345 x 102

How the Instrument Processes Output

The instrument outputs alphanumeric character strings in response to a query command from the host. A query command always ends with "?" (see Tables 4-4 and 4-5). An instrument output string is terminated by a CR/LF (carriage return/line feed). When the host sends a string to the instrument, wait for the instrument to return a prompt before sending another command string. If a second command is sent before the prompt is returned, a device-dependent command error (!>) is generated and the second string is ignored. The prompts are in one of three forms:

=>	The command was executed.
	[Example, PRINT 1]
!>	The command was recognized but couldn’t be executed.
[Example, PRINT 3, which has no meaning]
?>	The command was not recognized due to syntax error.
	[Example, PRITN 1, spelling error]

Numeric outputs from the instrument are either integer values or scientific notation values. For example:

The query command RANGE? returns the number 3.

The query command ALARMS? returns the number 0.

A measurement returns +1.2345E+6 (1.2345x106).
