WHEN TO CHARGE THE INTERNAL BATTERY
The best time to charge the Lithium Ion battery is any time the indicator is not in use.
You need not wait for the Low Battery Indication –in fact it’s best that you don’t.
Charging the battery when not in use keeps the battery “fresh” and is the recom-
mended way to manage it.
When the battery needs to be charged, the Low Battery Indicator will start blinking in
the lower left-hand corner of the display. The indicator may be used for an additional 2
minutes before it automatically powers down. It is imperative that you charge the
battery at this time to avoid permanent damage.
HOW TO CHARGE THE INTERNAL BATTERY
This version ships with a pre-installed power connector and an external battery
charger. Simply link the two up, and plug the battery charger into a suitable AC wall
outlet. Note that the external battery charger is rated for IP54 only.

4 ADVANCED OPERATION
4.1 Hold operation
This mode of operation is enabled by setting F30 to “5” in the Setup Menu (see sepa-
rate installer’s guide for more information). This mode captures the weight of an un-
stable load, e.g. livestock, by freezing the weight on the display. Use the Motion Band
setting (F5) and the Percentage Hold setting (F36) to adjust this mode to your specific
application. When the weight has been locked onto the display, two arrows beneath
the weight display will be turned ON.
There are several specific hold modes, which are selected thru the F35 setting.
AUTOMATIC (F35 = 1) –Automatically locks weight on the display when stable. If the
weight of the object on the scale changes by the F36 setting (e.g. 10%) then the sale
unlocks the held reading and relocks onto the new weight. This occurs during both in-
creasing and decreasing weight values.
MANUAL (F35 = 2) –Press the NET/GROSS key before applying any weight to the scale.
After the load has stabilized, the display will hold the weight reading on the screen un-
til the NET/GROSS key is pressed again. If the weight of the object on the scale changes
by the F36 setting (e.g. 10%) then the sale unlocks the held reading and relocks onto
the new weight. This occurs during increasing weight values only.
PEAK HOLD (F35 = 3) –The display updates as the load increases but not as the load
decreases. The value shown on the screen is the maximum weight applied to the scale.
Press the UNITS key to toggle between live mode and peak hold mode. The ‘P’ annunci-
ator is used to indicate that you are in Peak Hold mode. When you exit out of peak
hold mode, the old peak value is automatically cleared.
4.2 NET Weighing
Gross weight refers to the total weight of a product and its packaging. Conversely, net
weight refers to the weight of the product alone, discounting the weight of its con-
tainer or packaging; and tare weight is the weight of the packaging alone.
NOTE: This indicator stores the current tare weight in memory if the indicator is
properly powered OFF. If a tare weight is present at startup, the indicator will revert to
NET weighing mode and apply the stored tare weight.
1. If weighing an item in a container, place the empty container onto the scale’s
platter
2. After allowing the weight indication to stabilize, press the TARE key.
The display shows zero weight and the NET annunciator is activated

8000 REPEL Digital Weight Indicator User Manual
10
3. Place the object to be weighed on the scale’s platter and allow the weight in-
dication to stabilize.
The reading shown is the net value of the applied load
4. If necessary, toggle between the gross weight and the net weight by pressing
the NET/GROSS key
5. Press the TARE key again to clear the tare value and return to gross weighing
mode
4.3 Piece Counting
IMPORTANT NOTE: The piece counting function cannot be used in commercial (NTEP)
applications.
This mode of operation is enabled by setting F30 to “3” in the Setup Menu (see sepa-
rate installer’s guide for more information). This mode is used to indicate the number
of pieces of an item you have placed on the scale’s platform and is accessed by press-
ing the UNITS key. To ensure accuracy, the parts you are counting must be consistent
in weight.
The indicator uses the sampling method to determine the average piece weight (APW)
of the items you wish to count. When sampling items, always count the parts in your
hand and place them on the platform all at once. If the APW of the items is too light or
the total weight of the sample is too light, accuracy cannot be guaranteed. You will get
an error message, but piece counting will still be allowed. This indicator does not retain
the piece weight when powered down.
1. If the items you will be counting require a container, you must first tare the con-
tainer off by pressing the TARE key.
NOTE: The TARE key is inoperative when in sampling mode.
2. Press the UNITS key until “5 0” is indicated on the display. If the screen does not
show “5 0”, press the ZERO key once. The indicator is prompting you to place five
identical items on the platform.
NOTE: If you wish to change the sample number, simply press the UNITS key re-
peatedly until the desired sample number appears. Available choices are 5, 10, 20,
50 and 100. If you continue to push the UNITS key, the indicator will resort back to
weighing mode and you must start again from Step 2.
3. Place the sample items on the platform all at once and allow the weight indication
to stabilize. Once this is done, the zero indicated after the sample number will
change to a “–“. For example, “5 –“.
4. Press the NET/GROSS key to take the sample. If the sample size is large enough, the
indicator now displays the number of pieces on the platform and the “PCS” annun-
ciator is lit. If not, the indicator briefly displays “Lo” and automatically increments

8000 REPEL Digital Weight Indicator User Manual
11
the sample size. Repeat Step #4 with the new sample size.
NOTE: If the indicator continues to display “Lo” even after sampling 100 pieces, the
unit weight of the items you wish to count is too light for your scale to process ac-
curately.
5. To exit the piece count mode, press the UNITS key.
NOTE: The APW will NOT remain in scale memory when you exit piece counting
mode.
4.4 Peak Hold Mode
IMPORTANT NOTE: The peak hold function cannot be used in commercial (NTEP) appli-
cations.
This mode of operation is enabled by setting F30 to “5” in the Setup Menu and F35 to
“3” in the User Menu (see separate installer’s guide for more information). This mode
is used to indicate and hold the peak weight recorded during a specific process. The
most common application is testing the breaking point of a part or assembly. The 8000
REPEL records both positive and negative peak weights.
1. Push the UNITS key to active peak hold mode; the “P” annunciator turns ON.
2. Apply force to the piece –the display indicates and holds the peak force ap-
plied.
3. To toggle between positive and negative peak weights, use the NET/GROSS
key.
4. To reset both peak values to zero, press the ZERO key.
5. To exit peak hold mode, press the UNITS key again; the “P” annunciator turns
OFF.
4.5 Accumulation (Totaling)
This mode of operation is enabled by setting F30 to “1” in the Setup Menu (see sepa-
rate installer’s guide for more information). The mode allows you to add weighments
together to obtain a total weight. When a tare weight is active, the net weight is added
automatically.
1. Load the system with the weight that is to be added.
2. Press the PRINT key to add the current load to the weight accumulator.
3. The display briefly shows the message “ADDED” and then automatically returns
to the weighing mode.

8000 REPEL Digital Weight Indicator User Manual
12
4. If a printer is installed, a printout will be made. The gross, net and tare weights
are totaled.
5. No weight can be recorded twice. The system needs to be returned to the net
zero-range before another weight can be added.
6. The subtotal can be checked by pressing the PRINT key two times while at net
zero.
The display toggles between the net total weight and the number of weigh-
ments for 3-5 seconds.
•If the PRINT key is pressed during this period, then the total is printed (if option
is installed) and reset to zero.
•If the NET/GROSS key is pressed during this period, then the total is reset to
zero but not printed.
•If no key is pressed during this period, then the subtotal stays in memory and
the system returns to the weighing mode.
4.6 Printer
If the weighing system has been equipped with a printer, then weighing and time &
date data can be printed.
Here is an example of a possible printout:
ID.NO. 123456
DATE 01/28/11
TIME 10:23 AM
