2.2.11 Input and output functions (external control interfaces)
(1) GP-IB interface
All items that are operated on the panel can be GP-IB controlled.
Measured results comprising 5-digit exponential measured values, comparison
results and check of measured state are sent in one line of data strings.
Responses in 4-digit fixed decimal points or 5-digit integers are sent to query
commands.
(2) Specification of RS-232 interface function
All items that are operated on the panel can be RS-232C controlled.
Measured results comprising 5-digit exponential measured values, comparison
results and check of measured state are sent in one line of data strings.
Responses in 4-digit fixed decimal points or 5-digit integers are sent to query
commands.
(3) Specification of handler interface function
The interface for measurement by directly operating the meter using the handler
used in measurement.
