2.0 INTRODUCTION
Thank you for purchasing your new grain scale which is based upon the Core series
of Balances. The CQT1752GR model has been specifically designed to assist in the
grading of grain quality following screenings in relation to an initial sample weight of
grain, and to give an indication of yield in Kilograms per hectoliter (k.hl), and Pounds
per bushel (L.bu) Winchester.
There are 4 container sizes available --- 0.5liter, 1 liter, 1 pint and 1 quart as well as
positive and negative % dockage readings following up to 5 x screenings, plus a
memory facility for up to 5 x stored sample weights.
3.0 SET UP
3.1 UNPACKING AND SETTING UP YOUR SCALE
1) Remove the shipping protection screw and round cover as shown below using the
hex allen key supplied in the box. (It is advisable to keep the shipping protection
screw and the round cover for shipping to another location in the future).
Shipping protection screw
Round cover protecting the load
cell.
2) Place the pan (which comes separately packed) in the receptacle on the top cover.
Use the screw that is packed
separately in a bag with the
allen key to screw the plastic
pan into place. Be careful
when inserting the screw that
you do not use excessive
force as it can damage the
loadcell. Use light force to
secure the screw.
3) Place the stainless steel pan on top of the plastic pan.
4) Place the balance on a firm and flat surface for accurate weighing.

3.4 LOCATING AND PROTECTING YOUR SCALE
In order to keep your scale functioning at its best we suggest that you do the following:
Avoid extremes of temperature. Do not place in direct sunlight or
near air conditioning
vents.
Make sure the scale is located on a strong table and free from
vibration.
Avoid unstable power sources. Do not operate near large users of
electricity such as welding equipment or larg
e motors. Do not leave
the
batteries inside the scale if you are not using it for a long time.
Keep free from vibration. Do not place near heavy or vibrating
machinery.
Avoid high humidity that might cause condensation, and keep away
from direct contact with water.
Do not place near open windows, air
-conditioning vents or fans that
may cause a draught and unstable readings.
Keep the scale
clean, and do not stack material on the scale when it
is not in use.

4.0 BASIC OPERATION
4.1 TURNING ON THE SCALE
Plug in the unit using the AC adapter or insert batteries and press the [on/off] key.
1) The scale will show grn- X.X, “X.X” meaning software revision number, “grn”
meaning it has grain scale software, and then show the voltage X.X Vol. “X.X” is
the voltage of the batteries if being used on battery power, or the regulated voltage
from the AC adapter. Following this the scale will then count from 0 to 9, and then
display "0.00g" with the Stable symbol, Zero symbol and the last chosen container
size indicator being shown.
2) The scale is now ready to be used.
3) To turn the scale off after use press the [on/off] key again. There is an auto
power-off function that will automatically turn the unit off, this can be set in the
parameters section.
4.2 ZEROING / TARE
You can press the [Tare] key to set a new zero point. Zero will be set if the reading on
the scale is less than 70g. This may be necessary if the weight is not reading zero with
no weight on the pan. The zero indicator will show in the top left corner of the LCD.
If you are using a container to weigh then you can place this on the platform and press
the [Tare] key, the display will show zero and NET on the display.
You can then weigh any material added to the container. Taring weight subtracts from the
scale’s total capacity.
Note: When the container is removed a negative value will be shown. If the [Tare] key is
pressed when the container has been removed it will again zero the scale.
4.3 WEIGHING
To determine the weight of a sample, tare an empty container, then place the sample in
the container. The display will show the weight and the unit of weight currently in use.
The stable indicator will light up when the reading is stable.
4.4 WEIGHING UNITS
Three weighing units are available: grams (g), Kilograms per Hectoliter (k.hl), and
Pounds per bushel (L.bu) based on the Winchester bushel.

4.5 GRAIN DETERMINING
1) Turn on the scale and wait for the scale to display zero. Press [CON/UNIT] to
select the container size you will use, an Indicator will show next to the container
size to confirm which one you have selected (for example below 0.5lt).
2) Place the empty container on the pan and press [TARE]

3) Load the 500ml container with the grain. The screen shows the net weight (the
first net weight) of the grain (in this example the total weight is 400g).
qt
pt
Smp 0.5lt lt
stored
At this point you can press the [CON/UNIT] key to view the yield values calculated
in k.hl and L.bu based on the net weight in the container.
4) To store this weight as the initial sample value, press the [STORE]key, the
display will show “Store smp” and then return to the last weighing mode, an
indicator above Smp/stored will show to confirm the sample weight has been
stored in the memory.

stored
The container can now be removed from the scale and a screening performed.
5) Replace the same 500ml container on to the scale with the grain that is left
following the screening. The display will show the net weight of the grain that is
left, for example 300g left meaning 100g removed.
Again at this point you can press the [CON/UNIT] key to view the yield values
calculated in k.hl and L.bu based on the new net weight in the container.
qt
pt
Smp 0.5lt lt
stored
6) In order for the scale to calculate a negative or positive dockage following the first
screening press the [STORE] key, Store 1st will be displayed. The new net weight
will be entered into the memory and calculate the % grain remaining and removed
against the initial sample weight value stored at point 4.
Note that in order to perform a new STORE the scale has to go back to ZERO or a
negative value, removing the container to perform a screening allows the display
to go to a negative value which then permits the new STORE to be performed
when the container is placed back onto the top pan.
The first dockage result will then be displayed, and by pressing the [CON/UNIT]
key further results can be viewed including dockage, the net weight in grams
which was used in the calculation, and also the new yield values.
Pressing the [RECALL/CE] key unlocks the display for further weighings. Pressing
the [RECALL/CE] key again continuously will show you the same results with
reference to a particular screening, this can be done at any time and will progress
from the 1st screening through to the last screening stored showing all results.
Once all of the stored results have been displayed the next press of the
[RECALL/CE] key will exit you from these results.
7) A further screening can now take place following the same procedure as above
with the next net value being stored. Following the storing of the new net weight
the same information is available by pressing the appropriate keys. Screenings
can be repeated for up to 5 times with each result able to be stored and %
dockage, grams, yield and net weight values to be recalled. Each time a net
weight is stored the display will show Store x (x being the number of the screening
performed).

confirm deletion of the stored values and the indicator above Smp stored will go
out.
New tests can now be performed.
If the balance is turned off during the weighing process, it will retain the stored
information in the memory so that you could then complete the tests without
having to start again due to a loss of power.
Once a sample weight has been stored the scale will not allow you to change the
container size.

7.0 CALIBRATION
Calibration may be required when the scale is initially installed or moved to a new
location.
Over time and use, mechanical deviations may occur so it is recommended that you
calibrate your scale regularly.
Before calibrating you should make sure you have a suitable weight. The weights should
be known to an accuracy that is appropriate for the balance being calibrated, for
example, OIML Class F1 type or ASTM E617 Class 2. If you do not have proper weights
do not attempt calibration.
1) To enter into the calibration parameter turn the power off, switch the scale on and
during the counting up sequence press the [TARE] and [STORE] keys together,
then release these keys.
2) The display will show UnLOAD, remove any weight from the pan.
3) Press the [TARE]key, the weight value used for the last calibration will be
displayed.
4) To select a different calibration weight value press the [STORE] key. This will
cycle you through the weight values that can be selected for your calibration,
values available are 500g, 1000g and 1500g.
5) Once you have selected the weight to use press the [TARE] key.
6) LOAD will be displayed, place the calibration weight on the pan.
7) Once the stable sign is shown press the [TARE] key.
8) If the weight is within 5% of the last calibration the display will show PASS, exit the
calibration routine and return to normal weighing mode. If the calibration is not
successful the display will show FAIL and exit the routine, if the calibration fails try
again.
