Line 10 Resets the Model 2001 to default operating conditions.
Line 20 Disables continuous initiation and aborts operation. This places the Model 2001 in
the idle state.
Lines 30 Configures the instrument to perform five measurements.
and 40
Line 50 Performs an immediate initiation (:INITiate) to restart the measurement process and
sends the *OPC? command.
After all five measurements are performed and the instrument has returned to the idle state, an
ASCII “1” will be placed in the Output Queue.
Line 60 Addresses the Model 2001 to talk. This sends the “1” from the Output Queue to the
computer.
Line 70 Displays the “1” on the CRT.
Line 80 Returns the instrument to the default operating configuration.

the Model 2001 is addressed to talk, the code is sent from the Output Queue to the computer.
The code is made up of two comma separated fields. The first field indicates the presence or ab-
sence of extra memory.
0 No extra memory (8k bytes volatile)
MEM1 Memory Option 1 (32k bytes non-volatile)
MEM2 Memory Option 2 (128k bytes non-volatile)
The second field indicates the presence or absence of the Model 2001-SCAN scanner card.
0 No scanner card installed
2001-SCAN Model 2001-SCAN installed
Example: The following response message indicates that Memory Option 2 and the scanner card
are installed:
MEM2, 2001-SCAN
Programming Example 10 OUTPUT 716; “OPT?” ! Request option ID code
20 ENTER 716; A$ ! Address 2001 to talk
30 PRINT A$ ! Display option ID code
