Description
<b> = 1 or ON Enable autozero
0 or OFF Disable autozero
:STATe? Query state of autozero
This command is used to disable or enable autozero. When enabled, accuracy
is optimized. When disabled, speed is increased at the expense of accuracy.
Important Note: Before you can enable or disable auto-zero, the Model 2000
must first be in the idle state. The Model 2000 can be placed in the idle state
by first disabling continuous initiation (:INITiate:CONTinuous OFF), and
then sending the :ABORt command. After sending the :STATe command,
readings can be re-started by sending :INITiate:CONTinuous ON or :INI-
Tiate.
PRINT #1, "output 16; :init:cont off; :abor"
PRINT #1, "output 16; :syst:azer:stat off; stat?" ' Disable autozero
PRINT #1, "enter 16"
LINE INPUT #2, a$
PRINT a$
PRINT #1, "output 16; :init:cont on"
NOTE
When finished, be sure to re-enable autozero.
