Keithley 2750/E Digital-Multimeter, DMM, 2750/E Datenbogen

The Model 2750 has three overlapped commands:

•

:

INITiate

•

:INITiate:CONTinuous ON

•

 

*TRG

The INITiate commands remove the Model 2750 from the idle state. The device opera-
tions of :INITiate are not considered complete until the Model 2750 returns to idle. By 
sending the *WAI command after the INITiate command, all subsequent commands will 
not execute until the Model 2750 goes back into idle.

The *TRG command issues a bus trigger that could be used to provide the arm, scan, and 
measure events for the Trigger Model. By sending the *WAI command after the *TRG 
command, subsequent commands will not executed until the pointer for the Trigger Model 
has finished moving in response to *TRG and has settled at its next state.

Programming example – The following command sequence shows how to use the WAI 
command to allow the 2750 to wait for the programmed measurements to be completed 
before requesting a reading. 

SYST:PRES

‘ Returns 2750 to default setup.

INIT:CONT OFF

‘ Disables continuous initiation.

ABORt

‘ Aborts operation. Places 2750 in idle.

TRIG:COUN 1

‘ These two commands configure the 2750 

SAMP:COUN 30

‘ to perform 30 measurements.

INIT

‘ Starts measurement process.

*WAI

‘ Sends the WAI command. Program waits for

‘ 2750 to go into idle before executing next 

‘ command. 

DATA?

‘ Requests one reading.
