The meter GL2M type
intended to moisture & relative
permittivity measurements
of the soft and thin layer
The GL2M is very accurate and sensitive metering unit
intended to determine moisture content in the tea leaf.
Every single measurement pertain to measure single
layer (single leaf) – see addendum “ ” of the manual.
dditionally are once taked also measurements of leaf
body thickness and temperature, also air ambient relative
humidity and temperature as well.
Before every measurement is essentionally to run the
calibration procedure.
To protect against potential errors is not possible to
pass over it.
Mentioned procedure removes all ambient temperature and
moisture influences on mechanical parameters of sensitive
thickness sensor.
In case of big mechanical stress, like rapid drop the
unit on the floor or on the desk would be required to
take more detailed calibration doings described in the
attached "thickness sensor calibration" point.
Driving down the external arm equiped with OLED display
bring the meter to work and simultaneously bring also to
taking hold of the sample inserted in to the measuring
aperture. The internal arm touch the leaf body with
controlled force about 1N regardless of the pushing
force applyied on the external arm, defined further as
“ possible lowest force”.

1.Starting the calibration procedures:
Before running the unit, the measuring aperture must
be free of dust and other substances.
To start - PUSH and continue pushing the arm (with
possible lowest force), you hear the 2kHz sound and see
at the display the message as below:
.
If the aperture is clear and empty the GL2M proceed the
thic ness calibration state. If not, the procedure will
restart. For positive check, the procedure takes about
two second duration, at the end you hear short "chirp"
and stop of the 2kHz sound, next see at the display:
B.
The ifo let you to stop push the arm and lift the arm
off itself. Whenever the unit detect that the arm is
lifted up you hear the 2kHz sound.
The GL2M inform that now is in the offset callibration
state. The procedure takes up to one second. duration,
at the end you hear next short "chirp" , stop of the 2kHz
sound and see the display:
C.

Screen "C" inform that the GL2M is ready to measure
the leaf moisture content and also leaf body thickness
leaf temperature, the the ambient air relative humidity
and ambient air temperature as well.
Caution: If at any step of described calibrations
you will stop manipulate the unit - the GL2M will
automatically switch off after 5s. or 13s. depending
on present calibration state.
2.Ta ing the measurement:
The GL2M is designed to measure moisture content in the
pure tea leafes body and the moisture content of crushed
tea leafes as well. How to prepare the crushed leafe
sample on PCV plastic tray and the way of measure is
described in addendum “B” at the end of manual.
Let insert the leaf body in to the sensor aperture.
Please pay attention to place the leaf body on the
mirrored central point of the plastic red stand-off.
In front of this point, at the upper arm is located the
infrared temperature sensor which must "see" the leaf
body to determine the leaf temperature. It is needful
to provide accurate moisture content enumerations.
Next push and continue pushing the arm (with
possible lowest force). The measurement takes about
two second duration, at the end you hear short chirp
and see at the display the data like example below:
D.
If the meter identify that the measured substance is
the leafe body – the screen wil show in the left top
corner the letter “L”, as on figure D. For presence of
crushed tea leafes inserted on plastic tray – the screnn
will show the letter “P”, as on figure C.

Every measurement is automatically stored in one
of 30 memory banks. t the above screen can see that
presently, the working memory bank has the number "20".
The GL2M is programmed to take up to 16 different
measurements with current averaging of all results
in to the destinated memory bank.
The averaged values are: leaf moisture content, the
leaf body thickness and leaf body temperature as well.
t the screen you can see the averaged results and also
the current average number, at above screen it is "01".
The readiness duration between every measurement
is no longer than 13s. fter 16th measurement or after
the measurement duration readiness state greather
than 13s. the G2LM will switch off with increasing
about one the number of working memory bank,
for instance: 1 to 2,,, 29 to 30, and 30 again to 1.
If in course of the measurement duration period
the user will simply push and close the arm without
any leaf inserted in to the sensor aperture, the GL2M
will automatically restart new callibration procedure
preceding next measurement readiness. ll without change
of the working memory bank number. This option protects
again "waste" the memory bank in case of bad or improper
done measurement, for example after measurement realized
with not acurately inserted leafe.
If the user's concern is to take measurement without
averaging, is possible to realize it by closing the arm
after (as described) every separate measurement or
letting the GL2M to switch off automatically after 15s.

3.Charging the battery:
The unit is powered with help of 3pcs. of type
rechargeable Ni-MH batteries. The state of capacity
is focused at the display, like at the above example
57%. Below 10% of capacity the unit will automatically
switch off, therefore to ensure working continuity
is good to keep charged batteries as is only possible.
To charge batteries, is provided the micro USB socket
available at the body of GL2M. The charging process will
begin after connection with any USB plug from the
working PC or external +5V/300m charger.
Caution: During the charging process the unit can't
measue anything except the battery state.
Caution: It can be used any +5V Battery Charger equiped
with micro USB plug, for example cell phone charger.
The maximum charging time is less than 3 hours, the
charging process is fully controlled through GL2M
microcontroller and the charging state is shown at
the display as next below:
E.
To carry out the charge is required to connect the
powered USB in to the GL2M USB socket. If the unit was
in measurement rediness duration state or totally
switched off the charging process will start accordingly,
the display will show as above.
When the batteries achieve the maximum charge, the
display will show 99% and the charging process will
start to work in standby mode.
Therefore is possible to charge the batteries without
paying attention on the process.

6.Thic ness sensor calibration:
In case of the thickness sensor mechanical deregulation
is neccesary to correct potential measurement errors.
To fix the problem let measure any thin nonconductive
layer with known thickness.
The value should be in range between 0.20mm and 0.50mm.
Next, with help of GLM software, change the
parameter described as "Kt" to obtain as a result the
exact measured value which corresponds the reference
thickness.
nother thickness calibration method is described in
point 1. connected with initial calibration procedures.
In this case you must-have the attached stainless steel
roundel with calibrated thickness – exact 1,000mm.

Addendum “A”.
Tea leafe anatomy with example of the common leafe anatomy:
Colorized tea leafe cross-section (scanning electron
microscope):
The GL2M unit determine the water content as a result of
measure the dielectric property of the part of leaf. It
depends on place of test. Within every species of leafe,
the anatomy is repetitive. Therefore taking measurement in
a few parts of leaf (or many leafes in succesion), next
averaging the results – is possible to obtain the very good
approximation of dielectric constant right for the leaf,
the water content as well.
Placing in the measuring aperture many leafes at once
lead to false results because the serially placed few
leafes are buliding other than on above drawings,
nonroutine and incalculable spatial distribution of leaf
particles. It preclude to take real measurements by GL2M.

Addendum “B”.
The PCV plastic tray to prepare the pulp sample of
crushed tea leafes:
The extra tool that let to measure the crushed tea leafes
pulp contain 2 different parts:
- The stainless steel roundel with 20mm diameter and 0,5mm
thickness....4pcs. per unit,
- The plastic tray with 4 round fossettes and 1mm deep.
To measure the pulp need to “schmear” the pulp over the
tray filling the fossettes.
Next, need to cover every filled fossette with the metal
roundel, no force, no special accuracy, providing no air
bubbles among substance, as for example:
1. 2. 3. 4. 5.
Next, insert in to the Gl2M aperture and measure every
point accordingly to recognition.
To achieve reliable result strongly advise to measure and
repeat measurement in conformity with GL2M possibilities.
fter measurement is neccesary to clean with water the
tray and roundels – to be ready for next measurement.

Addendum “C”.
Some advices how to explore the machine asap...
1.Check for the newest version of manual. The manual is
in PDF format ( read with pdf reader, acrobat reader,
or any windows web explorer ).
If you click with mouse the photo with GL2M visible
at www.asoni .pl you will see immediately the latest
version full manual on screen. We recommend to print out
the document. Please read it comprehendingly.
2.Make few checkings with the machine in one hand and
manual in second hand. Of course before anything you
should remove the blocking piece of gray foam inserted
between machine arms, it was done only for
intercontinental transportation machine security.
3.Set omputer up with USB drivers required to work with
GL2M. Run attached with “GL2M v1.09.exe” the setup
software "CDM21216_Setup.exe", works with any
windows version.
4. ttach the unit to the PC – firstly for charging only.
Check how it works to stay familiar with procedure.
The best way for the beginning is to run the unit,
pass calibrations and after it let connect the usb from
computer. During first minutes the computer will prepare
(itself, automatically) all neccesary drivers for this
particular unit. Of course if all USB drivers was
previously installed on computer.
5.Next, try to run the PC software "GLM v1.09.exe", after
several seconds ( when clepsydra disappear ) do
“connect”. Try the operation few times to be absolutely
sure how it works.
6.The unit is already calibrated for “Kt” and “Ke”
parameters, do not manipulate with it. The only what to
do ( if any ) is to fix “Km” parameter accordingly to
green leaf moisture, the parameter inside unit is
matching average specie of tea leafes. Before doing it –
you will have the question how to introduce new value –
this moment please contact with SONIK (call, sms, mail).
7.You have no reason to look in to battery compartment also
no reason to unscrew anything..
