2.2.18. MAIN MENU FUNCTION Output set-up
This menu item when selected will allow Analogue Output functions and Digital Pulse Output functions that have previously
been set-up in the unit to be altered or edited via the Keyboard and Display of the Model 2000.
When this menu item is selected the user will be prompted to enter a four digit numeric password, to gain access to the
calibration pages. It is possible to set-up a maximum of three different passwords and each of these passwords can be set to
allow access or not to the calibration pages, these passwords are the same as used in the EDIT mode. In its factory default
condition the three available passwords are 1111, 2222 and 3333. If an incorrect password is entered or the Model 2000 is
in secure mode then access to the Data items will be denied. Once access to the Output set-up mode has been achieved, a
selection menu will appear and the required group of data must be selected.

down) cursor keys and selecting by pressing the enter or return key. If Analogue is selected then a page is shown for each
of the four Analogue outputs on a particular Output board. Each page has variables:-
Value Analogue Output Variable name, can be altered from items in list.
Abs Absolute function On or Off.
Max Output maximum scaling factor.
Min Output minimum scaling factor.
Stream Flowing stream number.
Cal Calibration function min or max.
The items to be altered are selected by moving the display cursor to the required data item using the [ ↑ ] (for up) and [ ↓ ]
(for down) cursor keys and selecting by pressing the enter or return key. The new value is then entered using the numeric

If Digital is selected then a page is shown for each of the twelve Digital outputs on a particular Output board. Each page has
variables:-
Value Digital Pulse Output Variable name, can be altered from items in list.
Invert Output Inversion On or Off.
Cycle Output duty cycle, can be altered from items in list.
Divide Output pulse scaling factor.
Stream Flowing stream number.
Freq. Pulse Output frequency.
The items to be altered are selected by moving the display cursor to the required data item using the [ ↑ ] (for up) and [ ↓ ]
(for down) cursor keys and selecting by pressing the enter or return key. The new value is then entered using the numeric
