Eagle Microsystems EI-2000 - Manual (Page 7)

MODE 5: USER-ADJUSTABLE REMAINING
Typical application: chlorine gas cylinders. - Remaining and gross weights are displayable.
1. An empty scale should read zero. If it does not, press the ZERO pushbutton. If
“no 0” is displayed, access the calibration mode to zero the scale.
2. Place a full container on the scale.
3. “REMAIN” LED will light.
4. Use the UP and DOWN ARROW pushbuttons to adjust the remaining weight
displayed.
5. The SELECT pushbutton will toggle display between gross and remaining
weights.
Note: This operating mode mimics the standard modes of other manufacturer’s scales. The
ability to display the true “Gross” weight value allows the operator to verify the remaining
value displayed; overfilled cylinders can be detected.
!! CAUTION !!
IN MODES 2 & 5, THE DISPLAYED “REMAINING” VALUE CAN BE EASILY CHANGED TO GIVE AN ERRONEOUS
READING. BEFORE REMOVING THE VALVE FROM AN ”EMPTY” CYLINDER OR OPENING THE VALVE ON A FULL
CYLINDER, ALWAYS VERIFY THE REMAINING VALUE WITH THE GROSS WEIGHT.
REMAINING_WEIGHT = GROSS_WEIGHT - CYLINDER_WEIGHT - VALVE_WEIGHT.
HIDDEN PUSHBUTTON FUNCTIONS
Scale gross weight recalibration/restart:
When a cylinder or tank is on the scale (above the weight threshold in modes 2-5, see
parameters P116, P216, etc.), press and hold the SELECT pushbutton until the gross LED is
starts to flash. At this time, the user may now use the UP and DOWN arrow pushbuttons to
adjust the gross scale calibration. When satisfied that the weight is correct, press the
SELECT pushbutton to restart the scale. Depending on the operating mode, a new start
remaining weight will be calculated and the used display will be zeroed.
Tare lock:
If this function is enabled (parameter P030), operating modes that display the tare weight
(modes 1 and 4), will not allow adjustment of the tare weight without first holding the UP or
DOWN arrow pushbutton for three seconds. To store the new tare, press the SELECT
pushbutton to display the remaining weight.
Front Panel Configuration/Calibration/Diagnostic Access (FPA)
The user has the option of accessing ALL configuration, calibration and diagnostic functions
without opening the enclosure. Parameter P999 selects whether or not this is enabled (it is
set to no or yes).
EI-1000: Press and hold [SELECT] + [RIGHT ARROW] for greater than three seconds.
EI-2000: Press and hold [LEFT SELECT] + [RIGHT SELECT] for greater than three seconds.
When the FPA menu is first displayed, the CFG option is shown. The selections are
configuration (CFG), calibration (EI-2000 has CAL and the EI-1000 has CAL1 through 4),
