The READ? Command

The READ? Command changes the state of the trigger system from the

“idle” state to the “wait-for-trigger” state. When the specified trigger

condition requirements are met after the multimeter receives the READ?

command, the measurement will be initiated. The results are sent to the

output buffer right away. You must enter the reading data into your bus

controller or the multimeter will stop making measurements when the

output buffer fills. Readings are not stored in the multimeter’s internal

memory when using the READ? Command.

Using the READ? Command has a similar effect as using the INITiate

command followed immediately by the FETCh? command, except

readings are not buffered internally.

The INITiate and FETCh? Commands

These two commands provide the lowest level of control of measurement

triggering and reading retrieval, but offer the most flexibility. After you

have configured the multimeter, use INITiate command to change the

state of the triggering system from the “idle” state to the

“wait-for-trigger” state. The multimeter will start the measurements

when the specified trigger condition requirements are met after it

receives the INITiate command. The results are sent to the internal

memory and stored until you are ready to read them.

The FETCh? command sends the data in the multimeter’s internal

memory to the output buffer where you can read them into your bus

controller.
