Example:
With Alarm 2 set to trail alarm 1, if
A1Hi
is set to
1000
and
A2Hi
is set to
50
then Alarm 1 will activate at
1000
and alarm 2 will activate at
1050
(i.e. 1000 + 50). If Alarm
2 had been set at
-50
then alarm 2 would activate at
950
(i.e. 1000 – 50).

Displays and sets the digital display brightness. The display brightness is selectable from
1
to
15
,
where
1
= lowest intensity and
15
= highest intensity. This function is useful for improving the
display readability in dark areas or to reduce the power consumption of the instrument. See also
the

R.INP
function. When a
remote input is set to
duLL
the remote input can be used to switch between the display brightness
level set by the
brGt
function
and the display brightness set by the
duLL
function. The
display dull level is selectable from
0
to
15
, where
0
= lowest intensity and
15
= highest intensity.
This function is useful in reducing glare when the display needs to be viewed in both light and
dark ambient light levels. To set dull level go to the
duLL
function and use the
^
or
v
push
buttons to set the value required then press
F
to accept this value. The

SECS
function is enabled i.e. set to any value other than
0
.
Example:
With
duLL
set to
4
and
brGt
set to
15
and the
R.INP
function set to
duLL
the
display brightness will change from the
15
level to
4
when a switch connected to the remote input
terminals is activated.

function)
will automatically be set to the level set at the
duLL
function. The auto dimming feature can be

0
and
9999
seconds. A setting of
0
disables the auto dimming. The display brightness can be restored by
pressing any of the instruments front push buttons. The display brightness will also be restored
whilst one or more alarm relays is activated. In normal display mode (i.e. not in
CAL
mode) there
is a 2 minute delay period after the instrument is switched on during which the automatic display
