2 PREPARATION
2.1 Preparing the scale for use
1. Unpack the scale carefully and place it on a firm rigid vibration free table or bench.
2. The PT410 Series comes ith a stainless steel platform packed separately. Place
the platform in the locating holes on the top cover. Do not press ith excessive
force as this could damage the load cell inside.
. Do not place in direct sunlight or near air conditioning vents as these can cause
extremes of temperature.
4. Locate the scale a ay from sources of air currents occurring near open doors and
ventilation outlets as this can affect eighing stability.
5. Avoid unstable po er sources. Large users of electricity such as elding equipment
or large motors generate electromagnetic fields that can affect eighing accuracy.
6. Level the scale by adjusting the four feet. Raise the side or corner opposite the
bubble until the bubble comes into the centre circle. Ensure all four of the feet
touch the bench. If the scale rocks readjust the feet.
7. The Po er s itch is located under the right hand side to ards the front of the
scale. Once the scale has been s itched on, it ill go through a display test and
then re-zero to be ready for use.
8. When the battery needs charging the LED to the right of the eight display ill glo
red. To recharge the battery, plug the po er supply into the socket located under
the scale next to the ON/OFF s itch and connect to mains po er. The recharge
light ill turn to yello hile it is being charged and turns to green hen the battery
is fully charged.
9. The acceleration due to gravity varies around the orld. The force on the scale is a
product of the gravity value and the mass placed on the scale to eigh. As the
gravity value can vary in different orld locations so can the eight displayed for
the same mass. This Scale has been calibrated for a gravity value (acceleration
due to gravity) of g=9.799 m/s2. Discrepancies in readings at the location of
installation could be due to a different gravity value and adjustment of the scale
calibration may be needed.
2.2 Care of your scale
1. Do not allo any liquids to get into or come into contact ith the scale. If this
happens, ipe the scale dry ith a cloth.
2. Avoid objects impacting ith the scale. Do not drop loads onto the scale or load
ith a load that is greater than maximum capacity.
. The scale should be kept clean. The scale can be cleaned ith a damp cloth and
any cleaning agents should first be applied to a cloth and this cloth then used to
clean the scale. Avoid solvents as these can damage the case.
4. If the scale is not going to be used for some time, e recommend that it be cleaned
and stored it in a plastic bag in dry conditions. A desiccant sachet may be included
to prevent moisture build up. If the storage period is to be lengthy the battery
should also be removed.

5 DISPLAY
The scales have three display indo s- Weight, Unit Weight and Count.
5.1 Weight Window
This consists of a 6 digit display to indicate the eight on the scale.
An arro above the symbols ill indicate the follo ing:
●Lo battery,
●Net Weight Display, "Net"
●Stability indicator, “Stable”
●Zero indicator, “Zero”
5.2 Unit Weight Window
●This display ill sho the unit eight of a sample. This value is either input by the
user or computed by the scale. The unit of measure is grams on all scales.
●Indicators ill sho hen the scale has determined that there is an insufficient
number of samples to accurately determine the count: "Sample" or symbol.
●When the unit eight is not large enough to determine an accurate count, "U.
Weight" or symbol.
●In both cases the scale continues to operate and the indications are to alert the
user to a potential problem.
5. Count Window
●This display ill sho the number of items on the scale or the value of the
accumulated count. See OPERATION section.
●Indicators ill sho hen a value has been entered into memory hen the arro
above the "Memory" legend is on.
●Just under the “Count” display is an LED to indicate the status of the battery
charging. When the scale is plugged into the main po er the internal battery ill be
charged. If the LED is green, the battery has a full charge. If it is red, the battery
requires further charging and yello indicates the battery is being charged.

PT410 User Manual Rev6 101209
6 OPERATION
6.1 Zero the Display
●You can press the ZERO key at any time to set the zero point from hich all other
eighing and counting is measured, ithin 4% of po er up zero. This ill usually
only be necessary hen the platform is empty. When the zero point is obtained the
Weight display ill sho the indicator for zero.
●The scale has an automatic rezeroing function to account for minor drifting or
accumulation of material on the platform. Ho ever you may need to press ZERO to
rezero the scale if small amounts of eight are sho n hen the platform is empty.
6.2 Tare
There are t o methods to enter a tare value. The first uses the eight on the platform and
the second uses a value input by the user.
6. Normal Tare
●If necessary, zero the scale by pressing the ZERO key. The zero indicator ill be
on.
●Place a container on the platform, a value for its eight ill be displayed.
●Press the TARE key to tare the scale. The eight that as displayed is stored as
the tare value and that value is subtracted from the display, leaving zero on the
display. The "Net" indicator ill be on. As product is added only the eight of the
product ill be sho n. The scale could be tared a second time if another type of
product as to be added to the first one. Again only the eight that is added after
taring ill be displayed.
●When the container is removed a negative value ill be sho n. If the scale as
tared just before removing the container this value is the gross eight of the
container plus all product that as removed. The zero indicator ill also be on
because the platform is back to the same condition it as hen the ZERO key as
last pressed.
6.4 Digital Tare
●This method allo s you to enter a value for the tare eight from the keypad. This
is useful if all containers are the same or if the container is already full but the net
eight is required and the tare eight of the container is kno n.
●Remove all eight from the platform, press the ZERO key to zero the display.
●Enter the value for the Tare eight using the keypad, press TARE to store the tare
value. The eight ill sho a negative value equal to the tare.
●Place the container on the platform. The display ill then sho the eight of the
container minus the tare eight. Then hen the full container is put on the platform
the tare value ill be subtracted from the gross eight displaying only the net
eight of the contents.
●If the tare value keyed into the scale is not rounded to the same resolution as the
scale, the scale ill round the tare value to the nearest value possible. For example
if a tare value of 10.3g is entered onto the 6Kg/0.5g scale then the display ill sho
-10.5g.

7 COUNTING
7.1 Average Unit Weight
In order to do parts counting it is necessary to kno the average unit eight of the items to
be counted. This can be done by eighing a kno n number of the items and letting the
scale determine the average unit eight or by manually inputting a kno n unit eight
using the keypad.
7.2 Weighing a Sample to Determine Unit Weight
●To determine the average eight of the items to be counted it ill be necessary to
place a kno n quantity of the items on the scale and then key in the quantity being
eighed. The scale ill then divide the total eight by the number of samples and
display the average unit eight.
●If necessary, zero the scale by pressing the ZERO key. If a container is to be used,
place the container on the scale and press the Tare key.
●Place a kno n quantity of items on the scale. After the eight display is stable
enter the quantity of items using the numeric keys follo ed by SMPL key. The
number of units ill be displayed on the "Quantity" display and the computed
average eight ill be sho n on the "Unit Weight" display.
●As more items are added to the scale, the eight and the quantity ill increase.
●If the scale is not stable, the calculation ill not be completed. If the eight is belo
zero, the quantity display ill sho negative count.
7. Entering a Known Unit Weight
●If the unit eight is already kno n then it is possible to enter that value using the
keypad.
●Enter the value of the unit eight using the numeric keys then press the UNIT WT
key. The "Unit Weight " display ill sho the value as it as entered.
●The sample is then added to the scale and the eight ill be displayed as ell as
the quantity based upon the keyed in unit eight.
7.4 Parts Counting
●After the unit eight has been determined or entered it is possible to use the scale
for parts counting. The scale can be tared to account for package eight as
discussed in an earlier section.
●After the scale is tared then the items to be counted are added and the "Quantity"
display ill sho the number of items computed using the eight and the unit
eight.
●It is possible to increase the accuracy of the unit eight at any time during the
counting process by entering the count displayed then pressing the SMPL key. You
must be certain the quantity displayed matches the quantity on the scale before
pressing the key. The unit eight ill be adjusted based upon a larger sample
quantity. This ill give greater accuracy hen counting larger sample sizes.
7.5 Automatic Part Weight Updates
●The scales ill automatically update the unit eight hen a sample equal to less
than the count of the initial sample already on the platform is added to that initial
sample. A beep ill be heard hen the value is updated.
Page 8

PT410 User Manual Rev6 101209
●This process has some limitations hen there are significant variations in unit
eight bet een individual items. It is prudent to check the quantity is correct hen
the unit eight has been updated automatically.
●This feature is turned off as soon as the number of items added exceeds the count
used as an initial sample.
7.6 Checking the Alarm
●To check the alarm mode press and hold C key this ill sho check net hich is
the eight check alarm. Press and hold the C key again and it ill sho check pcs
hich is the counting alarm. Press and hold again this ill sho check off alarm
function off.

eight or count is < than lo set limit.The alarm can be set to OK for eight /
count bet een the high/lo range , beeps hen eight or count is bet een the
high & lo set limits.The alarm can be set to NG for eight / count that is higher or
lo er than the set limits, beeps hen eight or count is > or< than the set limits.
To change this setting refer to F10 beep in Section 10 Parameters.
7.7 Count Preset or Check-weighing
●This scale can be used to count check- eigh. When this feature is active an alarm
ill sound henever the count equals or exceeds a preset value.
●To set the Hi /Lo limits
Press PST key display ill sho Hi cnt Enter in high limit for counting alarm press
TARE key to confirm. Display no sho s Lo cnt Enter in lo count for counting
alarm press TARE key to confirm. Display no sho s Hi net Enter in high limit for
eighing alarm press TARE key to confirm. Display no sho s Lo net Enter in lo
limit for eighing alarm press TARE key to confirm. Display goes back to normal
eighing mode.
●To clear the value from memory, and disable the check- eighing feature, enter the
value "0" into the memory.
7.8 Manual Accumulation
●The values ( eight and count) sho n on the display can be added to the totals in
the accumulator by pressing the M+ key. The "Weight " display ill sho the total
eight, the "Count" display ill sho the total accumulated count and the "Unit
Weight" display sho s the number of times items have been added to the
accumulation memory. These accumulated totals ill be displayed for 2 seconds
before returning to normal.
●The scale must return to zero or a negative number before another sample can be
added to the memory.
●More product can then be added and the M+ key pressed again. This can continue
for up to 99 entries, or until the capacity eight display is exceeded.
●The total stored can be recaled at any time by press the MR key. The totals ill be
displayed for 2 seconds.
●To clear the memory press MR to recall the totals from memory and then press the
CE key to clear all values from memory.
7.9 Automatic Accumulated Totals
●The scale can be set to automatically accumulate totals hen a eight is placed on
the scale. This eliminates the need to press the M+ key to store values into
Page 9

PT410 User Manual Rev6 101209
memory. Each value ill be stored after the scale returns to zero. Ho ever the M+
key is still active and can be pressed to store any value immediately. As the scale
is programmed to store the eight once only, that value ill not be stored a second
time hen the scale returns to zero.

8 BATTERY OPERATION
The scales can be operated from the battery if desired. The battery life is approximately
100 hours.
When the battery needs charging the arro above the lo battery symbol under the
eight display ill turn on. The battery should be charged as soon as the arro above the
symbol is on. The scale ill still operate for about 10 hours after hich it ill automatically
s itch off to protect the battery.
To charge the battery simply plug into the mains po er adaptor. The scale does not need
to be turned on.
The battery should be charged for 12 hours for full capacity.
An LED located just under the quantity display indicates the status of battery charging.
When the scale is plugged into the mains po er the internal battery ill be charged. If the
LED is green the battery has a full charge. If it is Red the battery is nearly discharged and
yello indicates the battery is being charged.
The battery is shipped partially charged. To maximise its life and performance it should be
fully charged before use. Many batteries of this type sho an improved performance if
they are subject to full charge and discharge to lo battery arning for the first fe cycles.
Batteries do not last forever and ill eventually hold less and less charge or ill take
longer to come to full charge. The battery should be replaced once either of these
conditions becomes unacceptable.
