The T200H/M provides password protection of the calibration and setup functions to
prevent unauthorized adjustments. When the passwords have been enabled in the PASS
menu item, the system will prompt the user for a password anytime a password-
protected function (e.g., SETUP) is selected. This allows normal operation of the
instrument, but requires the password (101) to access to the menus under SETUP. When
PASSWORD is disabled (SETUP>OFF), any operator can enter the Primary Setup
(SETUP) and Secondary Setup (SETUP>MORE) menus. Whether PASSWORD is
enabled or disabled, a password (default 818) is required to enter the VARS or DIAG
menus in the SETUP>MORE menu.
There are three levels of password protection, which correspond to operator,
maintenance, and configuration functions.
