3.1.4 Changing the Alarm Level

A valid key entry sets the instrument at the "run ZERO" location of the maintenance menu. Press the

OPTION

pushbutton

twice to access the "set ALM" display, then press the

SELECT

pushbutton; ALM=0000" is displayed. This is called the alarm

update window, and the value displayed is the present alarm setpoint. The underscore cursor is under the far left digit. Press
the

OPTION

pushbutton to change the underscored digit; select the desired digit, and press the

SELECT

pushbutton to lock in

the desired digit and move the underscore cursor one position to the right. When the desired new alarm point is set
“new=XXXX” is displayed. Press either the

OPTION

SELECT

pushbutton to exit the alarm update window. If the new

alarm setting is valid, "exit" is displayed. Press the

OPTION

pushbutton to return to the operational display, or the

SELECT

pushbutton to return to “run ZERO”.

For the safety of the user, there are upper and lower limits past which the alarm setting is invalid, and the instrument does not
accept them. If an invalid alarm setting is attempted, after the numerical value is inserted in the "ALM=0000" window,
pressing the

OPTION

SELECT

pushbutton results in a momentary display of "INVALID" after which the display returns to

the alarm update window. Exiting the alarm update window at this point results in an alarm point setting unchanged from the
value present when the procedure was begun.

Factory default alarm setpoints and alarm limits are shown in Table 1 Appendix A.

3.1.5 Setting a New Key

A valid key entry sets the instrument at the "run ZERO" location of the maintenance menu. Press the

OPTION

pushbutton four

times to access the "set KEY" display. Press the

SELECT

pushbutton once; "KEY=0000 is displayed. A new key can be set

by changing the underscored number with the OPTION pushbutton and moving the underscore cursor with the

SELECT

pushbutton. After the new key is entered “new-XXXX” is displayed, press the

OPTION

SELECT

pushbutton to display to

“exit”, then press the

OPTION

pushbutton to return to “run ZERO”.
