ource via F2 fu e. It provide a VSTAB voltage of approximately 5V which upplie the IC8
upervi or microcontroller, the LCD1 LCD driver and the two analogou witche IC: IC9 and
IC15. The ame voltage charge the button cell B1 through D2 diode and R12 re i tance.
When there i no operating power ource in the device, the B1 button cell upplie the IC
power need (VORA) of IC6 clock.
The digital part of the mea urement electronic operate from the VKAP voltage, which i the
ame a the VSTAB voltage, but it can be witched off by the IC8 upervi or microcontroller
through OFF ign to the T3 tran i tor. The electronic of pre ure mea urement operate
through VANA power upply, which i created from a VKAP ign by the IC16 fix 4V
tabili ator.
High current con umption component (motor pump and valve ) operate from the VPOWER
voltage. Thi voltage i produced by the IC14 DC-DC tran former and it i u ually 3.6 V, but
the IC1 main microcontroller can increa e it up to 4.6 V via a GEAR ign. The DC-DC
tran former i connected to the power ource via the F1 fu e. It operate only, if the main
microcontroller i witched on via VPEN ign and only if the upervi or microcontroller allow
it through a VPWR ign. In ca e of witching it off, the operation of the motor and the valve
i attached via the T2 FET a well. Thi dual cut off i a afety function, o that it will al o
happen in ca e of any component failure.
The upply (VRXD) of the T4,T5 tran i tor i normally between 4.5 and 5 V. There i an off
mode of the device, when it' „totally” witched off. In thi ca e the upervi or
microcontroller IC8 witche even thi upply off in order to decrea e the current
con umption.
In the stand-by mode of the device, the upervi or microcontroller IC8 regularly read the
tatu of the two pu hbutton of the device, the TIMER interrupt line of the real-time clock
IC6, and the pre ence of any ignal on the optical erial line. If either pu hbutton i pre ed,
or the real-time clock IC6 end a TIMER ignal, or a character i received on the optical
erial line, the upervi or microcontroller IC8 witche the other part of the device on
(VKAP, VANA). Now the device i in on mode.
Then, in thi on mode of the device, the upervi or microcontroller IC8 ha mainly afety
function .
In it on mode, the ABPM-05 device i controlled by the main microcontroller IC1. The main
microcontroller execute the program tored in the IC3 EPROM, and it u e the IC4 external
RAM during runtime, too. It read the current time from the IC6 real-time clock and it et
the real-time clock to end a TIMER ignal after 1 minute. It communicate with the IC6
real-time clock and the IC7 LCD driver through the SCL and SDA of the I2C bu .
The mea urement plan (monitoring chedule) and the re ult (blood pre ure and pul e rate
reading , event marker , ervice and error code ) are tored in the IC5 EEPROM. The main
microcontroller can read and write the EEPROM u ing a imulated I2C bu , but writing ha

tran ferred to the u er’ per onal computer.
The pneumatic y tem of the ABPM-05 device con i t of the motor pump MOT1, the
operating valve V1, the afety valve V2, the pre ure en or IC17, the blood pre ure
mea urement cuff, and the airway connecting component . Du t protection of the pneumatic
y tem i en ured by du t eparation filter , one on the uction ide of the motor pump
MOT1, another in the tube going to the cuff connector.
The piezo-re i tive pre ure en or bridge IC17 convert pre ure level in the pneumatic
y tem to electric ignal. The bridge i upplied by a current generator con i ting of the
active component IC11B, T7-T9. The output ignal of the pre ure en or bridge i going
through an amplifier-filter tage ba ed on the operating amplifier IC12, IC11A and IC11D to
the internal AD converter of the main microcontroller IC1. The bridge balance at zero
pre ure level i et by the choice of appropriate value re i tor for po ition R32 and R33,
while the amplification by the choice of an appropriate value re i tor for po ition R41.
For the increa ed accuracy of pre ure mea urement, the o cillation ignal are amplified the
AC-coupled tage ba ed on the IC11C operating amplifier, then they are converted by the
internal AD converter of the main microcontroller IC1.
The upervi or microcontroller IC8 open and clo e the afety valve V2 due to the
command received from the main microcontroller IC1. For afety rea on , however, it
keep the afety valve clo ed for maximum approximately 3 minute . If it doe not receive a
command from the main microcontroller to open the afety valve within thi timeout, it
open the afety valve and re et the main microcontroller.
The operating valve V1 i controlled by the main microcontroller IC1. The valve will be
opened if there are ome maller pre ure tripping (low pre ure) during the
mea urement .
The motor pump MOT1 i controlled by the main microcontroller a well. In order to be more
ilent, the motor u ually operate on a lower voltage. In ca e of a higher pre ure, the main
microcontroller increa e the voltage of the motor through a GEAR ign.
The buzzer BZ1 (which give an acou tic acknowledgement if a pu hbutton of the device i
pre ed) and the jumper JP1 (which erve only calibration purpo e ) are connected to the
main microcontroller IC1.
At the appropriate command, the main microcontroller IC1 mea ure the voltage of the
operating power ource through the re i tor network con i ting of the re i tor R76 and
R75, and it write the re ult to the LCD, thu making it po ible for the u er to check the
remnant power of the AA ize batterie .
The IC13 DC-DC tran former check the inlet voltage through the R66, R67 re i tance
divider. If the value fall under the afe rate, the upervi or microcontroller IC8 witche the
main microcontroller IC1 off, attache the operation of the motor and the opene the clo ed
valve . The main microcontroller will be kept witched off a long a the power upply i too
low and it' operation will be only allowed if the power upply i back to the normal level.

REPAIR METHODS
J1.0 Airtightness problems
1. If the cuff is eaking, exchange the cuff.
2. If the device is eaking, check and point out the cause. If the system is eaking heavi y, most frequent y tubes are disconnected or oose.
In case of minor eaking (5-20 mmHg in one minute), it is possib e that one of the rubber components is worn or the motor pump is
eaking. Separate sma sections of the pneumatic system after pumping up to ocate the eaking.
J2.0 Pushbuttons
1. If the buttons can be hard y operated or they get stuck, the reason is usua y the contamination of the knobs. Disassemb e the housing,
remove the button knobs, c ean the knobs, the buttons, and the housing around them.
2. The unre iab e operation of the buttons can be the resu t of a wrong assemb ing of the device /housing/. Pay attention to carefu
assemb ing after repairs.

TYPICAL PROBLEMS
•There is nothing on the LCD
Check power supp y (E2.0).
•The devi e is on, but measurements annot be started
Check power supp y (E2.0).
•The devi e does not arry out the preset measurement program (s hedule)
Check the vo tage of batteries in the device. Check power supp y (E2.0). Check the functioning of buttons. Check the c ock circuit (E4.0).
Read out the resu ts of the wrong measurements. If there are service codes, you can use them in searching for the error.
•Complaint: „The devi e does measure but it does not store the results”
It is often not an error of the device. It is a frequent comp aint if the device starts the measurements at programmed times but it cannot
comp ete them for some reason. This gives no or just a few va id readings (with BP va ues), but it may give the patient the impression
that a measurements were carried out. The reason may be an error of the device, but it can be the ow vo tage of batteries or a eaking
cuff, too. Checks and repairs shou d be based on the service codes you can read out from the device.
•The devi e beeps a lot
Read out the data of the device. If the device is programmed to measure at each minute or two minutes, the frequent y attempted (and
possib y unsuccessfu ) measurements may cause the frequent beeping, too. Checks and repairs shou d be based on the service codes you
can read out from the device.
•The devi e measures voltage ina urately
Measure the vo tage of the batteries with a mu timeter and compare them with the vo tage measured by the device. A s ight difference is
acceptab e (max. 0,2V) because the device does not measure exact y the same vo tage.
•The lo k does not work
Check power supp y (E2.0). Check the c ock circuit (E4.0).
•Complaint: „The devi e annot measure high blood pressure”
Check the preset pressure imit with the user settings point of the service program. If it is too ow, this caused the device to abort
measurements. Check airtightness (E5.0). Measure with the cuff that be ongs to the device because the prob em is typica y caused by
the cuff.

1. Check ng bas c funct ons
What to do Error Note
1.1 Insert 4 fully charged AA accumulators in
the battery compartment of the device. The LCD of the device remains blank or the displayed voltage is lower than 2.4V. Accumulators may be faulty, too. Check them and repeat this check with another set of accumulators.
Voltage display does not disappear
within 15 seconds. If there have been no accumulators in the device for weeks, the backup button cell inside may have run down.
Wait an hour and recheck.
1.2 Check the voltage of the AAaccumulators
with a multimeter. The difference between the voltage shown by the device and that measured
with the multimeter is >0.3V
The consumption of the device slightly decreasesthe
voltage of the accumulators as measured by the device.
1.3 Check the „stand-by” and the „pumping to
open air” current consumption of the
device. Then disconnect the multimeter
from the device.
Current consumption >5mA in stand-by
mode or >700mA while pumping to
open air (no cuff connected).
The internal resistance of the multimeter disturbs the
power supply of the device. If its internal resistance is
too high, the device cannot even switch to stand-by
mode.
1.4 Pressthe buttons and watch the LCD. There is no beep on pressing a button or
some LCDsegments are faulty. Disconnect the multimeter before this step because its internal resistance may disturb the operation of the
device.
1.5 Connect the device to the PC,start the
service program, choose Connect. No connection. Time should be on the LCDbefore the connection.
The operation of the device is uncertain. Another PCprogram (TSR) may disturb the connection.
1.6 Set the clock of the device with the clock-
setting function of the service program.
Read it back and recheck after 24 hours.
The date is wrong or the clock is more
than 5 minutes late or fast. If you do not suspect that the clock is faulty, it is enough to wait for a short time. Before setting the clock of the
device, check and adjust the PCcalendar and clock, too.
1.7 Program the device with the User program
and wait for a measurement. The device cannot be programmed or it
does not measure at the programmed
time.
Program the device only if you have not found any errors
so far, because error codes in the device are deleted by
the programming.
1.8 Pressthe event button, then the start
button and measure your blood pressure The device does not measure the blood pressure. Apply cuff to your arm and do not move during the measurement. Record the result as seen on the LCD.
1.9 Read out and check the event and the
reading with the User program. The measurement or the event is missing or the result of the blood
pressure measurement is wrong.
Data are not stored if the data memory of the device is
already full.

2. Check ng the pneumat c system, a rt ghtness and measurement accuracy
This stage checks the device and/or the cuff. If you want to check the device only, apply a flawless, normal size cuff around an approximately 10-15
cm diameter cylinder with a rigid wall (artificial arm). When there is no pressure, there should be approximately half an inch free room between the
cuff and the cylinder. A better solution is to use a high thermocapacity, ½ liter air tank instead of the cuff. Connect cuff or air tank to device.
Connect device to PC.
What to do Error Note
2.1 Start the airtightness test in the service
program.The device does not start pumping
within 15 seconds. Before the connection the time should be on the LCD.
2.2 Wait: the device is pumping. Pumping does not stop in 1 minute Leaking; may be caused by the fault of the cuff, too.
Wait: 2 seconds after pumping, the
pressure should decrease to about
250 mmHg.
Pressure is >270 mmHg or <220 mmHg
Wait 1 minute: leakage test. >3 mmHg with air tank
>6 mmHg with cuff around a cylinder Leaking may also be caused by the fault of the cuff.
Wait: deflation speed test. >1600 ms with air tank
>2400 ms with cuff around a cylinder Check both displayed deflation values.
Safety valve test. >5 sec with air tank
>8 sec with cuff around a cylinder
2.3 Disconnect cuff/air tank. Start another
airtightness test with free air connector. The pressure displayed by the device is higher than 2 mmHg. Nothing should block or obstruct the pneumatic system.
2.4 The pressure in the pneumatic system
must be 0 before this step. Connect
external pressure meter, pump and valve
and check and ensure that pressure is 0.
Then start the pressure measuring point
of the service program.
The device does not switch to pressure
measuring mode in 15 seconds.
2.5 Set 100, 200 and 300 mmHg with the
pump and the valve on the external
pressure meter. Check LCDdisplay on
device.
Difference is >3 mmHg. When defining the error, take the inaccuracy of your own
pressure meter into consideration, too.

ABPM-05 service and error codes BP5I4202 – 2006.05.15.
ABPM-05 service and error codes
The ABPM-05 device creates a 1 byte lon service code in case of unsuccessful
measurements or errors. This code refers to the cause of the error. Then the device creates
a simplified error code from the service code. The device stores both codes in its EEPROM.
The simplified error code will be displayed on the LCD, too. The user needs the simplified
error code only. The service code is meant for service and development purposes. Any
future modification of the internal pro ram may affect the service codes without notice (e. .,
new service codes may appear), but the error codes will be unchan ed.
Service and error codes do not have an absolute certainty. Almost any code can occur due to
electric disturbances, and movements of the patient may also imitate several kinds of errors,
too. The need for absolute error identification is secondary to tolerability, patient compliance
and safety. Therefore, the pneumatic system of the device may not be under pressure lon
enou h to identify the cause of an error exactly. Codes confirmin one another or the same
codes occurrin repeatedly are very likely to show the cause of the error properly.
Displayin the service code on the LCD may be necessary for service purposes. The
procedure to achieve this is purposefully difficult – you have to press and hold the extra
measurement button while an error code is displayed on the LCD, and when the volta e
appears on the LCD, you have to press the event button, too, then release both buttons.

List of service codes with explanation with corresponding error codes in italics
The followin list contains service codes and correspondin error codes. Numbered lines in
the description part explain the actions that should be taken to identify and fix the causes of
the iven code. Actions to take are listed in the order of probability. First follow instruction
#1, if this does not help, proceed to instruction #2, etc. Repairs should be done in
authorized services only!
80 90 UNUSED SERVICE CODE
1. No repairs necessary. If encountered several times, exchan e device.
81 9The watchdo circuit of the supervisor microcontroller has si nalled.
Operation of the supervisor microcontroller was disturbed by some electric
si nal but it resumed automatically.
1. No repairs necessary.
2. If encountered several times, check the solderin of the supervisor
microcontroller. Exchan e device if necessary.
82 9The watchdo pro ram function of the supervisor microcontroller sensed an
error.
Data of the supervisor microcontroller show that the main microcontroller
has been in a iven state for too lon (10-150 sec, dependin on state).
1. No repairs necessary.
2. If encountered several times, check the solderin of the supervisor
microcontroller. Exchan e device if necessary.
83 9The watchdo circuit of the main microcontroller has si nalled.
Operation of the main microcontroller was disturbed by some electric si nal
but it resumed automatically.
1. No repairs necessary.
2. If encountered several times, check the solderin of the main and the
supervisor microcontroller, the ROM and RAM. Exchan e device if
necessary.
84 99 The device senses lastin pressure with open valves.
The value of the analo si nal measured at zero pressure has to fall
between iven limits. Either the pressure measurin circuit went wron or
the device was not able to open the valves and it is under pressure. The
latter case is hi hly improbable since the device has two valves controlled
by two different controllers. The device checks the pressure continuously
and if the above case persists, it does not start measurements. It tries to
open the valves every minute, stores service and error codes, and displays
error codes. The acoustic si nal relatin to the displayed error code cannot
be disabled.
1. Exchan e the device.

85 2The measurement was interrupted by the patient.
The patient pressed the measurement button durin a measurement
process.
1. No repairs necessary.
2. If it is not caused by the patient, check and repair the button.
86 2The measurement was interrupted by the patient.
The patient pressed the event or the day period button durin a
measurement process.
1. No repairs necessary.
2. If it is not caused by the patient, check and repair the button.
87 3Low volta e.
The measurement was aborted due to low volta e of the operatin power
source.
1. No repairs necessary.
2. Check volta e.
88 31 On the first pumpin , the pressure is permanently too low.
There is no cuff connected or the device is losin air heavily (e. ., a tube in
the pneumatic system is disconnected).
1. No repairs necessary.
2. Check airti htness.
89 32 On the first pumpin , the pressure increases extremely fast (clo in ).
If the air tank is too small, the pressure increases very fast on pumpin
(more than 100 mmH in one second). Its reason is the clo in of the
device or the cuff (e. ., there is some water in the device or the tube of
the cuff is broken) or possibly – very rarely – the fault of the pressure
measurin circuit.
1. No repairs necessary.
2. Check for clo in .
8A 33 On the first pumpin , the motor pumps for too lon .
The device is losin air or there is a hole in the cuff.
1. Chan e cuff
2. Check airti htness.
8B 1Clo in – by pumpin .
If the device stron ly overpumps or overdeflates, it is likely that the tube
of the cuff is broken. Since on the very first pumpin the pro ram directly
checks for clo in (see service code 89), it is possible that this
phenomenon is caused by the movin of the patient. Therefore, nothin
happens on the first detection of this phenomenon, but two subsequent
occurrences cause the device to abort the measurement and enerate this
service code. The reason of the error is probably the movin of the patient
either directly or by breakin the tube of the cuff. This service code
indicates that a measurement was aborted after an overpumpin .
1. No repairs necessary.
2. Check for clo in .
8C 1Clo in – by deflation.
This is the same as service code 8B, except that the second phenomenon
(when the measurement was aborted) was not an overpumpin but an
overdeflation. Contrary to service code 8B, this error can be caused by an
error of the operatin valve.
1. No repairs necessary.
2. Check for clo in .

ABPM-05 service and error codes BP5I4202 – 2006.05.15.
8D 1Clo in – overpressure.
There is overpressure in the device but it is probably the side effect of the
situation described at service code 8B. Probably, it was caused by the
movin of the patient or the breakin of the cuff tube.
1. No repairs necessary.
2. Check for clo in .
8E 1Measurin time safety check si nal.
The device checks measurin time at three levels (measurin al orithm,
safety check of the main microcontroller, supervisor microcontroller), and
this is the si nal from the middle level. Since it is not the first (al orithm)
level that si nalled, the reason is some error, probably a temporary
disturbance.
1. No repairs necessary. If encountered several times, exchan e device.
8F 1Device re ularly cannot step to required pressure level.
The error is probably caused by the movin of the patient or less probably
by some temporary clo in .
1. No repairs necessary.
2. Check for clo in .
90 9UNUSED SERVICE CODE
1. No repairs necessary. If encountered several times, exchan e device.
91 99 The zero pressure is too hi h when startin the measurement.
When startin the measurement, the value obtained on definin the zero
pressure is too hi h. The pressure measurin circuit went wron or the
valves are closed and the device is under pressure.
1. Exchan e the device.
92 8Pressure over the preset limit for too lon .
The movin of the patient increased the pressure over the preset pressure
limit for a prolon ed period. The error is directly caused by the movin of
the patient, but the ori inal reason is the improper settin of the pressure
limit. By increasin the preset limit, the error can be simply eliminated. The
overpressure can possibly be caused by the clo in of the cuff tube, too.
1. No repairs necessary.
93 8A pressure step over the pressure limit would be necessary for the
measurement.
The device tried to step to a pressure that the pressure limit does not
allow.
1. No repairs necessary.
94 8The device tried to pump above the pressure limit.
When pumpin to a pressure level, the pressure always decreases a little
after the motor pump stops. To ensure the accurate settin , the device
pumps a little over the required level. However, it cannot do so around the
preset pressure limit because overpressure may cause the measurement to
be aborted. Even in this case, it can usually reach the required pressure
with maximum two attempts. This service code means that the device
made several attempts but could not succeed. The service code may si nal
some minor leaka e, too.
1. No repairs necessary.
2. Check airti htness.
