Keypad Lock OptionOption 3025
The keypad lock option is used to prevent un-authorised access to the programming menu. When this option is ordered, a new sub-
menu called “CODE” appears at the end of the programming sequence. See programming page 8. Three levels of keypad lockout are
available: Level 0 - Full access to programming menu. Level 1 - User only has access to alarm set point values. Level 2 - Total
programming menu lockout.
If this option is ordered, the factory default is “Lev 0”. If the keypad has been locked with either level 1 or 2, then the word “PASS” will
appear on the display if the user attempts to enter programming mode. Pressing the menu key will return the instrument to normal
display mode. However, if the user wishes to enter the programming menu, then when the word “PASS” appears, press in
succession, 1 second apart, all four keys from right to left.
