Table 6-2 C-12 Menu Hierarchy
Menu selections and instructions are detailed in the following sections of this operating manual as
assigned in the Main Menu column of Table 6-2 above.
Field editing in the C-12 is slightly different than the methods used in some of the other similar Met
One Instruments, Inc. products.
The flashing cursor ■ is moved to the field to be changed with the ▼▲ keys. Once the desired field
is highlighted, the ENTER key must be pressed to open it for editing.
A ▼ symbol will appear next to opened fields where a pick list is available and the ▼▲ arrow keys
can then be used to cycle through the available choices. Once the preferred option is highlighted,
press the ENTER key again to select it and lock the field. To return to the previous menu, press
ESC.
If a numeric field is opened for editing, the cursor will be positioned at the leftmost digit. Use the
◄► keys to move the cursor to the digit to be modified and then use the ▼▲keys to
increment/decrement the value. Once all the digits have been set to the required value, press the
ENTER key again to lock the field. To return to the previous menu, press ESC.
Use the ESC key to cancel any edit that may be in progress. The ESC and MENU keys are used
to exit the current menu and return to the previous menu level. If the Main Menu is currently
selected, the monitor will exit to the Main Sampling Screen.
6.3 Start or Stop Sample
This screen is used to begin or end the C-12 sampling
operations. It will be labeled on the main menu as either
START SAMPLE or STOP SAMPLE. The label indicates
the action that can be taken when entering this screen.
Once selected, press the START or STOP softkey (shown in
the START mode in Figure 6-4) to begin or end sampling.
