Users Manual

The default meter setting is: volts tic, autoranging, secondary display inactive. A different power-up configuration can be set by pressing Sand Eat the same time; the present configuration of the meter then becomes the power-up configuration.

A description of message exchange options:

5A. The size and behavior of the input buffer.

The input buffer size is 350 bytes. If the input buffer fills, the IEEE-488.1 bus will be held off until there is room in the buffer for a new byte.

5B. Which queries return more than one <RESPONSE MESSAGE UNIT>, Section 6.4.3.

The *IDN? query always returns four<RESPONSE MESSAGE UNITS>. The CAL? and MEAS? queries may return one or two <RESPONSE MESSAGE UNITS>—one if only the primary display is in use, two if both the primary and secondary displays are in use.

5C. Which queries generate a response when parsed, Section 6.4.5.4.

All queries generate a response when parsed.

5D. Which queries generate a response when read, Section 6.4.5.4.

No queries generate a response when read by the controller.

5E. Which commands are coupled, Section 6.4.5.3.

No commands are coupled.

6.A list of functional elements used in constructing device-specific commands. Whether <compound command program header> elements are used must also be included, Section 7.1.1 and 7.3.3.

Device-specific commands used:

<PROGRAM MESSAGE> <PROGRAM MESSAGE TERMINATOR> <PROGRAM MESSAGE UNI T> <PROGRAM MESSAGE UNIT SEPARATOR> <COMMAND MESSAGE UNIT> <QUERY MESSAGE UNIT> <COMMAND PROGRAM HEADER> <QUERY PROGRAM HEADER> <PROGRAM DATA> <CHARACTER PROGRAM DATA> <DECIMAL NUMERIC PROGRAM DATA>

7.A description of any buffer size limitations related to block data, Section 7.7.6.5. No block data is used.

8.A list of <PROGRAM DATA> elements which may appear within an <expression> as well as the maximum sub-expression nesting depth Any additional syntax restrictions which the device may place on the <expression> shall also be included.

No sub-expressions are used. The only <PROGRAM DATA> functional elements used are <CHARACTER PROGRAM DATA> AND <DECIMAL NUMERIC PROGRAM DATA>.

9.A description of the response syntax for every query, Section 8.

RATE?, FUNC1?, FUNC2?, RANGE1?, RANGE2?, BUTTON?, EEREG?, DBREF?, HOLDTHRESH?, RELBASE?, *ESR?, *SRE?, *TST?, and *OPC? all return <NRI

NUMERIC RESPONSE DATA>.

FUNC1?, FUNC2?, COMP?, and SERIAL? all return <CHARACTER RESPONSE DATA>.
