Operation
– While ‘
unit’
is displayed press the ‘
↵
’ key to enter the subroutine. The LED
now flashes the currently selected engineering unit while the LCD display shows the
corresponding moisture level. Use the ‘
12
’ key to scroll through the options until the
required unit is flashing on the LED. Press the ‘
↵
’ key to select the new engineering units.
Pressing the ‘
S
’ key at any time reverts to the ‘
unit
’ screen without saving any unit changes.
Note:
See DS5000 Specification for detailed information on Engineering Units.
9.2 AL 1 & 2
Description
– The AL 1 & 2 menu option allows the user to set 2-alarm trigger points. The
trigger points can be any value within the operating range of the currently selected
engineering units. The alarm triggers can be either a risings moisture levels (Hi), or a falling
moisture levels (Lo).
Operation
– While ‘
AL 1
or
AL 2
’ are displayed pressing the ‘
↵
’ key enters the subroutine.
The LCD now displays either ‘
Hi
’ or ‘
Lo
’. Use the ‘
12
’ key to select the required option
and then press the ‘
↵
’ key.
Note
- If the ‘ ’ key is pressed instead of the ‘
↵
’ key the DS5000 will return to the ‘
AL 1 or AL 2
’
screen on the base level, without saving any changes.
Once the ‘
↵
’ key is pressed, ‘
SET1
or
SET 2
’ will be displayed. The user can now escape
using the ‘
S
’ key or continue by pressing the ‘
↵
’ key. The current or default trigger point
value is displayed. Use the ‘
S
’, ‘
T
’, ‘
12
’, & ‘
↵
’ keys to enter the required trigger point.
Pressing the ‘
↵
’ key confirms the alarm settings and returns to the ‘
AL 1
or
AL 2
’ display.
Note
– The only way to leave the numerical part of this routine without saving is to allow the 60-
second timeout to occur.
9.3 bELL
Description
– The bELL menu option allows the user to set the internal buzzer to On or Off.

the ‘
bELL
’ screen on the base level, without saving any changes.
9.4 PrES
Description
– The PrES menu option allows the user to enter the line pressure and sensor
pressure in PSIg, barg
,
Mpa (PAS) or kg/cm
2
(gcS), so that the displayed absolute moisture
readings (PPMv, PPBv, g/m
3
and lb/MMSCF) can be pressure corrected and pressure
dewpoint can be displayed. When a pressure has been entered into the DS5000 the LED
display alternates between the current engineering unit and a ‘
≡
’ icon to indicate the data
displayed is pressure corrected.
