2.0 INTRODUCTION
Thank you for purchasing your new grain scale which is based upon the Core series of
Balances. The CQT1751GR model has been specifically developed and designed to be
used to assist in the grading of grain to asses the quality of the grain as well as to give an
indication of the Kilograms per hectolitre (kg/Hl).
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
Allen key supplied in the box. (It is advisable to keep the shipping protection screw
and the round cover along with the packing box for using during shipping to another
location in future).
Shipping protection screw
Round cover around the screw
2) Place the pan (which comes separately packed) in the receptacles on the top cover.
Use the screw that you
removed to screw the plastic
pan into place. Be careful
when putting the screw in that
you do not use to much force
as it can damaged the
loadcell. You should just be
able to 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 large motors. Do not leave
the batteries inside the scale – if you are using the scale with the
AA batteries and are not using it on 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. The CQT1751GR has a stacking feature allowing more
than one unit to be stacked on top of each other. For more details on
this see the section on storing.

4.0 BASIC OPERATION
4.1 TURNING ON THE SCALE
Plug in the unit using the AC adapter or power from the batteries and press the [on/off]
key.
1) The scale will show automatically grn- X.X, “XX” meaning software revision
number “grn” meaning it has grain scale software and then show the voltage X.X
Vol where “X.X” is the voltage of the batteries if being used on battery power or the
AC adapter after that the scale will then count from 0 to 9 for a few seconds. Finally
it will display "0.0g" with the Stable symbol and Zero symbols being lit up.
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 [Recall / 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
[Recall / 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 [Recall / Tare]
is pressed when the container has been removed it will again zero the scale.
4.3 WEIGHING
To determine the weight of a sample, first 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
Two units are available: grams (g) and Kilograms per Hectolitre (Kg/Hl).
