DETF basic scale
Introduction
The DETF basic scale is a mechanical basic
module for various seca scales. It is used for the
electronic determination of the weight of adults.
For the electronic measurement of the mechanical
quantitiy “force” a double-ended tuning fork
sensor (DETF) is used.
The above principle of operation has been realized
on the one hand with a knife-edged load lever
system to meet higher accuracy requirements and
on the other hand with a more cost effective
bearing-determined load lever system to meet
slightly lower requirements.
Weighing
When a load is placed on the scale, the force due
to gravity is transferred from the platform (1) to the
load lever system.
The long load lever (2) transmits the force via the
bending element (5) on to the hook (6). The force
is reduced in accordance with the transmission
ratio of the load lever. The force applied to the
short load lever (3) is added to the force on the
long load lever via the centre suspension (4).
A bending load acts on the bending element that
increases the tensile force acting on the
pretensioned tuning-fork sensor (7). This increases
its resonant frequency in a non-linear way, which is
measured by the connected electronics (8) and
converted into a weight using the stored
characteristic curve. The weight is output on the
digital display (9).
together, but also exert an initial load which is
necessary to reduce the hysteresis.
In the bearing-determined load lever system two
springs exert a force which corresponds to a
preload of approx. 15 kg.
In the knifed-edged load lever system 4 springs
exert a force which corresponds to a preload of
approx. 11 kg. The platform is prevented from
being lifted by an additional locking device onto
which the long load lever hits if the platform starts
to rise (not for flat scales).
Vibration-sensitive switch (optional)
Any force exerted on the platform acts via load
lever system, hook and overload protection device
on the vibration-sensitive swich (13) which is fitted
between overload protection device and platform.
The load causes the vibration-sensitive switch to
generate an electrical pulse which starts the
connected electronics.
Overload protection device
The force acting on the hook is transferred to the
overload protection device (10). This device is
pressed against the platform by a pretensioned
spring. If the load on the scale exceeds a
permitted value, the spring yields and the load
lever system is lowered.
Platform locking device
The platform retaining springs (11) do not only
hold platform, frame (12) and load lever system

Brief description of the DETF module
Introduction
The DETF module belongs to the family ofseca electronic modules and is used to determine weight
by means of a tuning-fork sensor system. The weight obtained is displayed on a separate display
module. To allow the module to be adapted to different scales, an EEPROM is integrated with which
it can be configured. A connection to the SeSAM bus (Seca's Serial Autoconfiguring Multicontroller
bus) is provided via which the scale can be calibrated and additional modules can be connected.
The following block diagram shows the most important function blocks of the force sensor and the
DETF module:
Weight measurement
A tuning-fork sensor screwed to a bending element is used as the weight sensor. If the scale is
loaded, the bending element exerts a tensile force on the tuning-fork sensor, thus increasing its
resonant frequency. By means of the bandpass filter the sensor is set vibrating at this frequency
which is then measured by the microcontroller.
Using the value obtained and the individual calibration data stored in the EEPROM the controller
calculates the weight.
The first value obtained after switch-on is used as the zeropoint. If the values obtained later on do
not deviate strongly from this value, the zeropoint is corrected in order to compensate for possible
drifts.
When the sensor is connected, care must be taken that the wires are not twisted to prevent crosstalk
from the output to the input.
Temperature measurement
As the value measured by the tuning-fork sensor is affected by temperature, the temperature is
measured regularly and compensated for accordingly.
Power supply
Power supply is provided by four AA size batteries and / or a seca mains transformer / desktop
mains unit. From the power supply the voltage is passed via a reverse voltage protection diode to an
in-phase regulator which provides a stabilized 3V supply voltage.
30-34-00-617 1

EE/Jensen

In order to avoid measuring errors due to almost flat batteries, their voltage is measured at regular
intervals. If the voltage drops below a certain limit, the user is alerted by the battery symbol in the
LCD. If the next threshold is undershot, „bAtt" is displayed and weighing is no longer possible.
In order to extend the on-time when the scale is mains operated, the microcontroller receives a
signal when a mains transformer is connected.
It is possible to use rechargeable batteries, but the batteries will not be charged in the scale.
EEPROM
The DETF module accommodates an EEPROM on which all parameters are stored that can be used
to influence the program sequence, for example various limit values or the coefficients for
determining the weight and for temperature compensation.
Furthermore, the scale can store values to be retrieved when the scale is switched on the next time,
e.g. the modules last connected.
Serial bus
To allow the scale to be calibrated and additional modules, such as displays, to be connected, the
DETF module is equipped with an interface to the SeSAM bus.
On this bus the stabilized and non-stablized supply voltages are available. Via a data and a clock
pulse line all relevant data is transmitted to other modules. A special start line is provided via which
the scale can be switched on or other modules can signal thatthey wantto send data.
Fault handling
If faults occur, the SeSAM bus initiates a fault message with the relevant fault code. Furthermore,
each fault message includes the number of the module type on which the fault has occurred and a
code which indicates how long the message is to stay on display and which displays are to be
suppressed.
The fault messages are transferred to the SeSAM bus and can be output by the display module
(module type for the DETF module = 1).
The following fault messages are implemented:
10 20 bit counter overflow
11 Counts outside the permissible range
12 Switch-on zeropoint outside the permissible range
13 Zero follow-up outside the permissible range
14 Fault in the kg value calculation
15 Recalibration fault
20 Battery voltage too low
21 Fault in battery voltage measurement
22 Fault in temperature measurement
23
Temperature range exceeded ( < 0°C or > 50°C)
30 General bus fault
32 Command buffer full
33 More than 8 slaves detected
40 EEPROM fault
41 Incorrect EEPROM access
50 Other fault
Instead of fault message 20 „bAtt" is displayed and „temP" instead of fault message 23.

From the quartz's 4.19MHz a time base is derived which controls all timed processes in the scale.
These are, for instance, various timeouts and the on-time.
After expiry of the on-time, the supply voltage for the bandpass filter, for voltage measurement and
for the EEPROM is switched off. All ports are setto zero-signal level and the quartz is stopped.
Recalibration
In order to compensate for linear measuring errors of the scale, which can, for instance, occur as a
result of the different forces of gravity at different geographical points, the module has a recalibration
function. Recalibration is performed via the SeSAM bus by means of a display module.

Brief description of the display module
Introduction
The display modules belong to the family of seca electronic modules and are used to display a
weight measured with a suitable module and transferred via the SeSAM bus (Seca's Serial
Autoconfiguring Multicontroller bus). Furthermore, the display modules accommodate the operating
elements and can process the weight (hold, tare, etc.).
The following block diagram shows the most important function blocks of the display modules:
Display
The weight displayed on the LCD is updated approximately every 0.8s. A maximum of five digits as
well as a few special characters can be displayed, which can appear as shown below:
TO DOO O*
TUUQQB;
◄ A HOLD TARE NET StS ►
Explanation of the special characters:
• The battery symbol is used to alert of the fact that the battery is going flat.
• The plug symbol indicates that the scale is operated on a mains transformer.
• The warning triangle signals that the weight displayed on the scale is not verifiable.
• Hold indicates that the weight display has frozen.
• Tare or Net show that a weight on the scale has been tared out.
• The left and right arrows point to additional explanations next to the display.
• The weightunits on the rightshow in which unit the measured weight is displayed.
Power supply
Power supply is provided via the SeSAM bus.

06.09.1999
EE/Jensen

With the exception of a start button that might be available, the connected buttons can be
configured as required for the particular model. These buttons can be pressed just lightly or longer
(longer than 1.5s).
If you press another button when switching on the scale, the scale will switch to the verification
counter and recalibration mode.
SeSAM bus
The SeSAM bus connects the display modules to the other modules. On this bus the stabilized and
non-stablized supply voltages are available. Via a data and a clock pulse line all relevant data is
exchanged. A special start line is provided via which the scale can be switched on or the module
can signal that it wants to send data.
Identification code
If several display modules are connected, an unmistakable ID code must be assigned to them using
soldering jumpers to ensure thatthe different modules are correctly addressed via the bus.
Backlighting (optional)
Some display modules are equipped with a power supply for LCD backlighting. It can either be lit
when the scale is switched on oronly when the scale is loaded.
Signal transmitter (optional)
Some display modules are equipped with a signal transmitter. A piezo diaphragm is used which is
controlled with a 4 kHz square-wave signal.
Fault handling
If faults occur, the SeSAM bus initiates a fault message with the relevant fault code. Furthermore,
each fault message includes the number of the module type on which the fault has occurred and a
code which indicates how long the message is to stay on display and which displays are to be
suppressed.
The display module displays its own fault messges on its LCD. Module type (for the display module
= 3) and fault number are output. In addition, the fault messages that other modules have
transferred to the SeSAM bus are displayed.
The following fault messages are implemented:
14 Fault in the kg value calculation
15 Recalibration fault
30 General bus fault
32 Command buffer full
33 More than 8 slaves detected
50 Other fault
51 Menu fault
Time base
From the quartz's 4.19MHz a time base is derived which controls all timed processes in the scale.
These are, for instance, various timeouts.
Recalibration
In order to compensate for linear measuring errors of the scale, which can, for instance, occur as a
result of the different forces of gravity at different geographical points, the module has a recalibration

function. To initiate the function, another button must be pressed when the scale is started. The
verification counter is then displayed which is incremented whenever the scale is recalibrated. It
enables the user to check whether the scale was manipulated. If, within five seconds, the button is
pressed longer than 1.5 s, the scale switches to recalibration mode. The scale now measures the
zeropointand waits to be loaded with at least Vi of the maximum load. By briefly pressing the button
the weight displayed can be decremented or incremented in steps of lOg until the weight of the load
placed on the scale is reached. The direction can be changed by pressing the button longer. To
stop recalibration the button must be pressed longer than 5s. The scale can be switched off any time
using the on/off button or by not actuating it for a while, thus aborting recalibration.
Optional functions
The functions "Tare", "Hold", "Autohold" and "Replace weight in repeat measurements" and various
menu functions can be implemented via a program on the EEPROM (on the weight measuring
module). The functions are explained below:
Tare:
The tare function can be assigned to a button by the EEPROM program. If the button is pressed, the
weight is tared out as soon as the display has settled, if it is within the permissible range. Pressing
the button again alternatively switches the tare function off or causes the weight to be tared out
again.
Hold and Autohold:
If the hold function is assigned to a button by means of the EEPROM, the weight reading is held on
display when the button is pressed as soon as the value has stabilized. Alternatively, the hold
function can be automated so that the weight will always be frozen when it has exceeded a certain
threshold and is stable.
The hold function is switched off after expiry of a predetermined time or by pressing the button
again. In addition the scale can be configured so that the hold function will be deactivated when the
scale is relieved, when the scale is relieved and then loaded again and / or when the load on the
scale changes significantly.
Replace weight in repeat measurements:
The scale can be configured so that the weight last displayed is displayed again in a measurement
when the scale detects that it has been loaded with almostthe same weight.
Menu functions:
Not all the functions listed below can be activated on the same scale.
When the menu button is pressed long enough, the scale switches to the setting mode. Here,
damping and weight display settings can be made.
When the button is pressed briefly, the scale switches to function mode. The following functions are
possible:
• BMI: From weight and height the body mass index is calculated using the following formula
BMI = weight[kg] / length[m] 2 BMI = weight [kg] / height [m] 2 .
• IDE: The deviation from the ideal weight calculated using the formula
0,9 x (length[cm\ - 100 ) 0.9 (height[cm] - 100) is displayed.
• UL: When a limit weight is overshot or undershot an acoustic signal is generated.
• DIFF: The difference to a second weight is output. The second weight can have been measured
using the autohold function, entered manually or stored when the difference function was last
called.

Description of the calibration mode for scales with modular
electronics
General:
Seca scales with modular electronics are fitted with a software-controlled calibration device
that is operated using the existing controls. This device can be used to recalibrate the
scales or to set the scales to different GAL values. During development of the calibration
device, special attention was paid to the following requirements:
• It must be possible to recalibrate the scales without any additional external
equipment/tools.
• It must be possible to calibrate the calibration device.
• It must be possible to recalibrate the scales without calibrated test weights.
• The calibration device shall be protected against inadvertent use.
Calibration counter
The scales fitted with the new, modular electronics are equipped with a calibration counter
allowing a software recalibration to be carried out according to the requirements for
calibrated scales. To carry out such a recalibration, the calibration counter setting can be
called up on the display of the scales and compared to the data given on the calibration
label mark (applies only for calibrated products). If the values are identical, the scales are
calibrated; whereas differing values match the situation of a broken calibration seal. Each
completed recalibration procedure is registered by the calibration counter, i.e. the number is
automatically incremented by 1.
Recalibrating the scales
Before the scales can be recalibrated, they must be switched to the calibration mode:
To do so, switch on the scales using the appropriate control. While doing so, simultaneously
press another control key (for example, the kg/lbs key). This causes the contents of the
calibration counter (i.e. the number of calibration procedures carried out so far) to be
displayed for five seconds (flashing).
During the 5 seconds the contents is displayed, press the kg/lbs key again and keep it
depressed (for more than 1.5 seconds) to switch the scales to the calibration mode.
If the kg/lbs key is not pressed within these 5 seconds, the scales are automatically
switched back to normal weighing operation.
When switched to the calibration mode, the scales first are in a decrementing state. This
state is indicated by a flashing "dec" that alternates with the currently measured weight.
Now place a test weight onto the scales. This test weight should have a weight of at least
25% of the maximum permissible load for the weight (we recommend a weight of approx.
66-75%). The weight shown on the display must match the test weight; otherwise, the
scales are maladjusted and the recalibration procedure must carried out in full length. To do
so, change the weight shown on the display using the kg/lbs key until it matches the test
weight.
If the value shown on the display differs from the test weight (if not, recalibration is not
required), estimate whether the required nominal weight is easier to reach by decrementing
or by incrementing. To toggle from the decrementing mode to the incrementing mode or
vice versa, press the kg/lbs key for more than 1.5 seconds (display indicates dec or inc).

Pressing the kg/lbs key for less than 1.5 seconds causes the weight shown on the display
to be increased or decreased by 10 g (depending on the mode currently selected). As the
resolution of the display is lower, the displayed value will not necessarily be increased or
decreased each time the kg/lbs key is pressed. Repeat the above procedure until the
displayed weight and the test weight match. Set the scales to the middle between two
division values by additionally incrementing or decrementing the value by n=d/(2*10). The
calibration process can now be completed by pressing the kg/lbs key for at least five
seconds. The scales compute and store a new linearity coefficient and will then be switched
off automatically. The scales are now calibrated. Remove the test weight.
Note:
To prevent improper calibration by improper use, a timeout control has been implemented
in the calibration mode, i.e. the time that passes until the next key is pressed must never
exceed five seconds.
However, this timeout control is only active for the phase when switching to the calibration
mode.
If, during this phase, 5 seconds have passed and no key has been pressed, the scales are
automatically restored to the weighing mode so that the procedure must be repeated.
To reduce calibration errors to a minimum, recalibration is only possible using a test weight
of more than 25% and less than 100% of the max. load; otherwise, “Er:0:15” will appear
on the display.
If the scales need to be set to a different GAL value, the displayed value must be matched
to the test weight value adapted to the GAL value correction. _
Example of a recalibration procedure:
The selected test weight is 100 kg.
The current weight shown on the display is 99.7 kg (max. difference of 300 g).
In this example, you must switch the scales to the incrementing mode to carry out the
recalibration procedure. After the kg/lbs key has been pressed (for more than 1.5 seconds),
a flashing "inc" is shown.
Now increase the value by the first 10 g (by briefly pressing the kg/lbs key). After this has
been done thirty times, the value 100.0 (rounded!) appears on the display although the
internal measured value still is 99.95 kg (not rounded!).
To correct this rounding error, increase the value by another 10 g to get exactly 100.00 as
the calculated value.
Terminate the recalibration procedure as described above.

Summary of a typical recalibration sequence:
Action carried out by the user Result
The scales are switched off. No values or characters on the display.
Press the kg/lbs key and keep it depressed
while simultaneously pressing the start key.
Release both keys.
Press the kg/lbs key for more than
1.5 seconds within the next 5 seconds.
5 seconds have passed and no key has
been pressed.
The scales are switched back to normal
weighing operation.
Place the test weight onto the scales.
Him
Decide whether to decrement or to
increment:
Incrementina:
Press the kg/lbs key for more than 1.5
seconds.
The incrementing mode is activated; "inc"
appears on the display.
Decrementina:
No action required as the scales are already
in the dec mode.
No output on the display.
Decrementing or incrementing:
Again briefly press the kg/lbs key (for less
than 1.5 seconds).
The measured weight is decreased or
increased by 10 g. Please remember that
pressing the key does not always change the
value on the display due to the low display
resolution. Only the rounded value is given.
Repeat this step until the measured weight
matches the test weight (format: xx.O kg).
The display indicates the test weight (format:
xx.O kg).
To correct this rounding error, decrement or
increment the value five times by another
10g.
The display output does not change the first
four times.
After the fifth time the value has been
decremented or incremented, the measured
weight appears; it now matches the test
weight.
The display indicates the exact test weight
(format: xx.00 kg).
Press the kg/lbs key for at least 5 seconds
until the system is switched off.
The display does not show any characters or
values any more.
