4I Moisture meter G610i
The Moisture Meter G610i gathers all the characteristics to provide the most accurate
reading on grains moisture.
With a single operation and without depending of the operator, the model G610i provides
a moisture reading withing few seconds, for a wide range of products.
With a simple keyboard of only 5 keys, it is possible to operate the instrument and
quickly setup it without requiring a long user training.
G610i enables the moisture analysis using the FLOW THRU technology. It is not necessary
to provide the sample external weighting, the temperature corrections, ad weights are
automatically performed, without using another resources, or additional tables.
The calibration curves for each cereal were obtained at the Gehaka laboratories, using
samples collected from several planting areas.
Using the standard stove method as reference, the measurement scales for each
product were created. These curves were transferred to the G610i memory and are
easilyidentiedbytheproductnameanditsversion.
If it is necessary to develop new calibration curves, there is a function in the web site
www.moisturetester.com.br that allows the creation, edition and installation in your
moisture meter G610i.
The G610i has three instruments into one, managed by a state-of-the-art internal
microprocessor. They are these three instruments: an electronic scale, which measures
the sample weight; a built-in digital thermometer, which measures the sample
temperatureinsidethechamberandtheG610itemperature,andnallyaCapacitance
meter, which indicated the percentage of moisture to
suer the correction from the other parameters further
up.
Its program runs all the required calculations, resulting in
extremely reliable and repetitive readings. It still performs:
automatic setting and checking of all the electronic circuits
for the good operation.
Introduction

Moisture meter G610i I 5
The FLOW THRU instrument drawing allows that quick readings are accomplished, that
is, in less than 40 seconds.
Simply select the product, spill the sample from the G610i Weighting Vessel, until it
BEEPS, load the sample,, the measurements will be taken and the moisture content will
beautomaticallyprovided.ThisallisdisplayedinanalphanumericdigitalLCDdisplay
(LiquidCristalDisplay), of easyreadingwith16characters and 2lines,inPortuguese
language.
TheG610ialsohasabidirectionalcommunicationporttypeserialRS232C.Therefor,it
is possible to connect the G610i to a printer so that the media can be printed in a label,
makingthecounterproofidenticationeasier,oritcanevenconnectthemetertoaPC
and transfer the information to a management system.
The G610i is run with an external power source type FULL RANGE, that is, the instrument
operationisassuredtomainsthatvaryfrom90to240VAC,protectingtheinstrument
against the mains oscillation.

Checkthepackagecarefully,iftherearemarksanddamagesinthecardboardbox,it
indicates that there were problems during the transportation.
Open the package, check the state of the G610i. Remove the equipment and check if all
the accessories are included.
Place the G610i on a stable table, so that it does not move during the operation. Remove
the adhesive tapes that hold the Drawer and check if it slides smoothly.
Connect the AC Adapter in the connector in the real panel and t it securely, taking
care to see if the plug is totally inserted in the connector. It is not necessary to check
the power supply voltage, the source is “Full Range”, and the mains selection is not
necessary. It is also recommended to use a voltage stabilizer.
When pressing the ON key, the G610i will start the operation, running a self-diagnosis
to check if its components are working properly. In the case the instrument veries
that any of is components is working incorrectly, it will display an error message in the
display regarding the failure.
The G610i can work connected in the outlet, or using an internal 9V battery. This
switching is automatically selected. It is important to not that, when working with the
9Vbattery,theDisplayBacklightwillbeswitchedoinordertosavethebatterycharge.
When the G610i is started, a percentage indicating the Battery status is displayed during
the self-diagnosis, note:
30% a 100% Normal operation
0% a 30% Request the battery change or charge
0% Indication of low battery, the G610i no longer works
The function “2. Battery Test” indicates the Battery voltage beyond the statue in the
percentage format.
The G610i shall be operated inside a location free from excessive dust and with a
temperaturewithin0ºto45ºC.

3. Get a product sample of at least 200g to which you want to know the moisture
and, using a plastic cup, slowly pour the cereal sample in the Weighting Vessel,
until the indication of 100% is displayed in the display, a beep will sound indicating
that the sample weight is correct. In the case that weight is exceeded, the display
will indicate a value higher than 100%, and the sample excess shall be removed
from the Weighting Vessel.

4. Pour the weighted sample in the G610i Load Hopper,
using the Weighting Vessel edge as reference.
Observe the drawing at the side, the Weighting Vessel
shall pour the sample from backward to forward the
G610i, the sample shall be poured quickly, do not
pour it slowly because it decreases the instrument
repeatability.
5. After few seconds, the G610i will indicate the value for the product moisture in the
display. If the Right/Left keys are pressed, the G610i will display all the measures
it has performed, that is:
When you select the Right/Left Keys, we will have:

6. After successfully concluding the
measurement, the G610i will send all
the measurement data to the printer or
computer through the serial output. An
example of the report is shown below.
NOTE: If there is a large dierence in
temperature between the product
and the G610i Chamber, where
the Temperature Sensor is locate,
it will wait until there is a thermal
balance between both. It can cause
the temperature measurement
to take a longer time to be carried
out. Thus, we have improved the
instrument accuracy, measuring
the sample real temperature.
7. After carrying out the reading discharge
theChamberusingtheDischargeButton.
8. When the G610i is indicating the
measurement results on the display and
a new sample is poured in the Weighting
Vessel, the G610i will carry on a new
measurement using the same settings as
the previous measurement. If the OFF key
is pressed, the function MEASURE will be
quit, returning to the main menu.
NOTE: If the moisture content is higher
than 22%, the G610i will request
the sample to be measured again,
repeating it three times to assure a
higher accuracy in the reading.

The Battery function is used to perform the measurement and indicate the battery
status at the moment. Its main function is to prevent it from running out of power during
an external measurement. Execute the procedures:
1. Press YES to enter in the “Battery” function. A screen will be displayed indicating
the Battery voltage and the charge percentage still remaining until it is totally
discharged. It is possible that a new battery indicates a percentage higher than
100% and it will be considered as discharged when it displays 0%. It is important
to note that the systems only switched to the Battery when the power Adapter it
is removed from the mains.
2. There are two errors that the Battery measurement system displays, they are
respectively:
This error indicates that an improper Adapter is being used to power-up
the G610i, there is a high risk of damages to the equipment electronics;
please, immediately remove the source that is being used and acquire a
new power Adapter at Gehaka.
This error shows that the battery is completely discharged; please provide
the battery change as shown later in this manual.
3. If the RIGHT ARROW is pressed, a report with the result will be printed, as shown
at the side:

4. Gehakastilloersanoptional,whichisthe
Rechargeable Battery for the G610i. This
Battery has the same mechanical aspect
as the disposable Battery; however it is
rechargeableNickelCadmium.Onlyinthis
case the power Adapter will e another with
voltage of 12V, enough to recharge the
Battery in 12 hours of loading. To verify if
the battery was totally charged, observe
the loading percentage in this function,
it must achieve approximately 120%,
and at this moment the Adapter can be
unplugged from the mains. The expected
autonomy for this Battery is of 10 hours
of continuous operation. There can have
variations depending on the model of
battery used.
