9.2.12 Adjusting alarm setpoints from the
display mode
Access to the alarm setpoints from the indicator
display mode is obtained by operating the
P
and
Up
push-buttons simultaneously as shown in Fig
12. If the setpoints are not protected by a security
code the alarm setpoint prompt 'SP1' will be
displayed. If the setpoints are protected by a
security code, 'COde' will be displayed first.
Pressing
P
again will enable the alarm security
code to be entered digit by digit using the
Up
and
Down
buttons to change the flashing digit, and the
P
push-button to move to the next digit.
If the correct code is entered pressing
E
will cause
alarm setpoint prompt 'SP1' to be displayed.
Pressing the
Up
or
Down
button will toggle the
display between the two alarm setpoint prompts
'SP1' and 'SP2'.
If an incorrect security code is entered, or a button
is not pressed within ten seconds, the instrument
will return to the display mode.
