Welcome for choosing and using our EUROB1016 intelligent pressure gauge. This manual enunciates
the functions and methods for use of intelligent pressure gauge in detail. Before using this intelligent
pressure gauge, please refer to this manual for your correct use.
Functions and Purpose of Use
Researched and manufactured by our company, EUROB1016 intelligent pressure gauge is a control
instrument, first of it’s kind produced in Europe. Not only does it assimilate the strongpoint of the similar
foreign products, but also it boasts its own characteristics, especially applicable for measuring and
controlling temperature and pressure at an identical point for high-temperature melting articles. This
instrument features fine appearance and complete functions with excellent anti-jamming performance,
which ensures reliable operation of the system.
This instrument adopts two-level four-bit led, respectively displaying actual pressure value and setting
value. Annunciate or be possessed of pressure upper limit or lower limit, which can be output via relay
contact, voltage pulse, bi-directional silicon-controlled trigger, and two-circuit constant current (or constant
pressure). Programs can be debugged fully automatically through panel operation and what you should do
for system calibration is just to push down buttons lightly. This instrument employs three kinds of anti-
jamming methods to ensure reliable functioning of the instrument: firstly, separate input from
microprocessor via photoelectric isolation circuit; secondly, adopt anti-jamming methods by applying of
software to ensure steady operation of software; and lastly, apply hardware program to monitor the system
and to enable automatic recovery of system program to normal operation after being jammed. It has been
proved through practice that high reliability can be ensured of system software by using the above
anti-jamming methods. System can thus function steadily and reliably.
This instrument is widely used for measuring and controlling of pressure of high-temperature melting
articles in industries such as petroleum, chemical fibers and plastics.

calibration.
●Adjustment state of internal parameters:
a)、Press Shift key for more than 5 seconds in measuring and the system enters into adjustment state of
internal parameters;
b)、Each time the Shift key is pressed, internal parameters are output sequentially. Symbols of internal
parameters are displayed on upper display window and currently set parameter values, lower display
window;
c)、Use Shift key, Up key and Down key to modify currently set parameter values;
d)、Press Shift key to confirm and store newly set values and call the next parameter;
e)、Press Shift key for more than 5 seconds or no key is pressed for more than one minute, the system will
automatically return from the adjustment state of internal parameters back to measuring state; f)、Press AC
key and meanwhile, point press Shift key, pressure zero can be cleared. Press AC key for more than 5
seconds and the actual pressure zero of last calibration can be recovered;
g) 、 Press Calibration key and point press Shift key simultaneously, the system goes to automatic
calibration. Please refer to related section on calibration for system pressure.

Self-calibration for system zero pressure: connect high-temperature fusion pressure transducer with
EUROB1016 intelligent temperature & pressure gauge according to operation manual. Properly connect 220
V AC power supply. Press ‘cal’ key and point press Shift key simultaneously after system POST, and then
the system starts fully automatic self-calibration. Calibration lamp starts flashing. Press Shift key all the
time during calibration until calibration is completed and the system returns automatically back to working
state.
Caution: System must be unlocked before self-test, i.e. set LCK parameter in internal parameter list to

zero. Otherwise there will be no response when pressing ‘cal’ key and Shift key. This function is to prevent
on-the-spot operators from Misoperation. Parameter for measurement range RN can either be set before
self-calibration or after that. Zero pressure must be ensured for induction head of transducer when
self-calibrating.
Attentions:
1 ． Transducer head must be free from collision and properly screw its protection cap when being
stored;
2 ． The instrument should be kept in humidity-free environment;
3 ． The instrument should work with rated voltage, otherwise it may result in unusual failures;
4 ． The instrument has functioned of temperature zero tracking. Generally, it can zero automatically.
But if temperature drift is so wide that it exceeds the automatic tracking range, press AC key and
point press Shift key simultaneously to calibrate zero pressure. If zeroing by accident, press AC
key for more than 5 seconds and zero calibrated in normal temperature is recovered.
Maintenance:
1 ． Numerical display ’88.88’ or ‘--‘indicates broken transducer leads or improper contact. Connect
properly.
2 ． No numbers displayed: check if 220 V AC power is connected. If not, check if there is output
from switch power supply.
3 ． Unstable numbers displayed: generally, it means that ground wire is improperly connected with
ground. Connect shielded wire properly with ground.
4 ． If major failures occur due to misoperation in connecting wires by clients, please contact us for
replacement of parts such as power board, CPU board, or display panel.
5 ． If repair work is beyond customers’ capability, please directly send to us. We ensure one-year
responsibility of repair and life-long maintenance.
