EXAMPLE: If the reporting range limit is set for 100 ppm and the dilution ratio
of the sample gas is 20 gain, either:
 a span gas with the concentration of 100 ppm can be used if the span gas
passes through the same dilution steps as the sample gas, or;
 a 5 ppm span gas must be used if the span gas IS NOT routed through the
dilution system.
5.5. SETUP  PASS: PASSWORD PROTECTION
The menu system 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.
