– The SPOLL command differs from the STB? command in that STB? interrupts
– If data is in the output buffer when you send the SPOLL command, that data
Examples
10 P=SPOLL (722) !SENDS SERIAL POLL, PLACES RESPONSE INTO P
20 DISP P!DISPLAYS RESPONSE

TRIGGER (GET)
If triggering is armed (see TARM command), the TRIGGER command (Group
Execute Trigger) triggers the multimeter once, and then holds triggering.
Syntax
TRIGGER 7
TRIGGER 722
Remarks
– The TRIGGER command generates a single trigger just as if the TRIG SGL
– If subprogram memory execution is suspended by the PAUSE command
Examples
TRIGGER 7 !SENDS GROUP EXECUTE TRIGGER (GET)
TRIGGER 722 !SENDS GROUP EXECUTE TRIGGER (GET) TO THE DEVICE AT ADDRESS

interrupting the microprocessor. Therefore, you can use SPOLL to monitor the
readiness of the multimeter for further instructions.

triggering is not armed (TARM command).
(multimeter command set), the TRIGGER command resumes subprogram
execution but does not generate a single trigger.
