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.
