RECHARGEABLE LEAD-ACID BATTERY
1. Battery Charging
The scale can charge the battery (lead-acid rechargeable battery,
6v/4Ah). Just connect the scale to the external power supply to
charge it. The battery will be charged regardless if the scale is on
or off. It takes approximately 12 hours to charge the battery to full
capacity depending on the voltage of the battery. If the battery
has been-discharged, a prolonged charging time is required to
bring the battery back to full capacity.
Red light: The battery is charging.
Green light: The battery is fully charged.
Built-in rechargeable
6v/4Ah battery

2. Low Battery
When the battery voltage falls below 5.7v, the low battery
annunciator will be turned on.
The battery must be recharged. Continued use (approximately 15
minutes later), the display will show in the weight
field. If the battery voltage drops too low for accurate weighing,
the scale will automatically shut off and you will be unable to turn
it back on. When the low battery indicator is displayed, the
operator should plug the power supply into the scale and then
into the proper electrical wall outlet. The scale will begin charging
the battery.
Notice
The battery should be recharged at least every 5 months
regardless if it is used or not.
After a long time storage, e.g. over 3 months, it is desired to cycle
(charge/discharge) the battery 3 times to let it restore to full
capacity.
When replacing the battery, pay much attention to the poles. The
positive (+) terminal must be connected to the red connector and
the negative (-) terminal must be connected to the black
connector. If connected wrongly, the battery will be damaged.
NOTE: The battery cover can be removed by loosening a
single captive screw. This screw remains attached to the cover
which prevents it from falling out of the cover or being dropped
and lost.

10
The capacity of the batteries will reduce over the years and
therefore also the total operation time of the scale. This is not an
error of the scale, but it is normal behavior or rechargeable
batteries.
POWER SUPPLY
Make sure the battery pack is installed in the battery box of indicator,
or, plug the connector of 12VDC /110~240 VAC 50/60Hz AC adapter
in the scale.
Adaptor plug

PANEL
LCD DISPLAY FUNCTION
1. lb
The lb annunciator is illuminated to show that the weight
displayed is in pounds. The UNITS key may be used to select
pounds as the weighing units.
2. kg
The kg annunciator is illuminated to show that the weight
displayed is in kilograms. The UNITS key may be used to select
kilogram as the weighing units.

13
3. NET
The NET annunciator is illuminated to show that the weight
displayed is the net weight. Net weight is determined by
subtracting the stored tare weight from the gross or scale weight.
The tare weight, usually the weight of the container, is entered
using the tare key. Note that the NET annunciator is only active
when a zero tare weight or tare weight value is stored and the
display is in the weight mode as shown by the illumination of the
lb or kg annunciator.
4. ZERO (Center-of-Zero)
The Center-of-Zero annunciator is located on the left of the
display and is illuminated to indicate that the weight is within +/-
1/4 division of the center of zero.
5. Insuf Sample
The Insuf Sample annunciator is located on the lower left of the
display and is illuminated to show that the sample is too small to
calculate an accurate piece weight. If the counting function is
continued without increasing the sample size, the scale will still
operate even though accuracy will be affected.
6. (Low Battery)
The Low Battery annunciator will illuminate to indicate that the
internal battery requires charging. No change in operation will
occur until just before the battery voltage drops to a level where
operation is affected. At this level, the scale will automatically turn
itself off.

14
7. M+
The M+ annunciator is located on the lower right of the display
and is illuminated to show that the display is in the Accumulator
mode and that the value displayed is the current contents of the
accumulator. Individual counts are adjusted via the ( M+ ) and
( MC ) keys or optionally, any count may be entered using the
numeric keypad. Note that when both the M+ and ADD
annunciators are illuminated, the current count has been added
to the accumulator.
8. (Stable)
The (Stable) annunciator is located at the bottom left of the
display and is illuminated when the WEIGHT display is stable.
9. ADD
The ADD annunciator is located at the bottom right of the display
and is illuminated when the scale is in the accumulator mode
(M+).
NOTE!
When the battery needs to be recharged, the CHARGING LED will
turn Red. After the battery has been recharged, the CHARGING LED
will turn Green.

KEY FUNCTION DESCRIPTION
Key Description
This key is used to weigh a known number of
pieces in preparation for a new
counting operation.
Sample quantities are entered using the numeric
keypad in any quantity desired.
Pressing this key will display the calculated
average piece weight from the current sampling
and counting operation. It will also allow the
manual entry of a known average piece weight
(using the numeric keys) to be used in the next
counting operation.
This key is used when setting the Quantity and
Weight Preset limits. During a counting operation
(with the limits set) if the quantity or weight
exceeds the limits, the error beeper will sound and
an error message will flash on the display.
The MC key is used to clear the accumulator. The
M+ and ADD annunciators will turn off to indicate
the clearing has taken place.

16
Pressing the M+
key will cause the scale to display
the contents of the accumulator (the number of
pieces accumulated since the last time the
accumulator was cleared).
The M+ key is also used to add the current piece
count value to the accumulator. The M+
annunciator will be selected to indicate the
accumulation has taken place.
The PGM
key is used to add or edit product look up
(PLU) numbers. Up to 99 PLU numbers can be
programmed. Note that the first 9 PLU’s are
assigned to the P1-9 keys and that all PLU’s can
be selected using the numeric keys.
Pressing the P# key will cause the scale to recall
the average piece weight
along with the saved tare
weight (if a tare weight was programmed)
associated with the product look up (PLU) number.
P1 ~ P9
Pressing these keys will cause the scale to recall
the average piece weight
along with the saved tare
weight (if a tare weight was programmed)
associated with the product look up (PLU) number
assigned to the key.
These keys are used to enter numeric data during
normal operations as well as
during calibration and
operational setup.

17
The key is used to perform different
functions depending on the current mode of
operation:
Data Entry: The key is used to
clear an incorrect entry from the display
without processing the data. If an incorrect
entry is made, press the key and
re-enter the correct data.
Pressing and holding the
key for 3
seconds will toggle the display backlight on
and off.
The ZERO key is used to perform a variety of
functions depending on the current mode of
operation:
Weight Display Mode (lb or kg annunciator on):
Pressing the ZERO key will set the weight display
to zero and turn on the ZERO annunciator if the
displayed weight is within ± 4% of scale capacity.
The TARE key is used to display the current tare
weight (or zero if no tare has been entered) and/or
using the numeric keypad, to enter a new tare
weight. It is
also used when entering a tare under a
Preset number.

18
Pressing this key will toggle the weighing units
between pounds (lb) and kilograms (kg). The
currently selected weighing unit is indicated by
illuminating either the lb or kg annunciator.
Metric Conversion
To change weighing units, press the UNITS key to
toggle between pounds and kilograms. Note that
either the LB or KG annunciator will illuminate to
indicate which weighing unit is active.
This is the decimal point key. It is used to enter a
decimal point where required when entering
numeric data.
The Enter key is used to signal completion of the
entry of data and causes the scale to process the
data entered.

19
POWER SWITCH
The Power Switch is located
on the bottom left side panel
towards the front of the scale.
Place the power switch in the
on position. The scale will
perform a brief lamp test. This
test consists of illuminating all
display segments and
annunciator LED's to allow
the operator to make a visual
verification that the display is
operational. After completion of the lamp test, the scale will display
the model number and software revision level and then the WEIGHT
display will change to show zero weight, indicating the scale is ready
for use.
Before using the scale, it should be “warmed up”
(turned on and unloaded for approximately 15 to 20
minutes).
