3 - GENERAL RECOMMENDATIONS
ÎATTENTION
The configuraon of the instrument is protected by a password and by the protecon code.
To accede at the configuraon parameters reset the password & the protecon code:
contact our technical office.
Don’t change these parameters to avoid malfuncon or breaking of the calibrator with risks
of serious personal injury.
- Posion of the probe:
To obtain the best result, follow the advises:
Measure the diameter of the probe being checked.
The diameter of the hole in the calibraon block must be higher than the diameter of the probe;
following this measure:
◊0,5mm for ø4,5÷8mm probes (max. operave range 600°C)
◊0,7mm for ø8÷12mm probes (max. operave range 600°C)
◊1 mm for ø12÷17mm probes (max. operave range 600°C)
◊Reduce this tolerance for max. operave range lower then 300°C
If this is not possible, use the reducon wells with the above-menoned tolerances (fig.1).
Avoid using holes which are too accurate and do not force the probes into the block.
Put the probe or the insert in the block only at ambient temperature; for reducon insert using
the tweezers.
Insert the probe up to the bo om of the block: the sensive element is in the opmal calibraon
zone (fig. 2).
Calibraon with a reference: take care to posion the two probes, the standard one and the
calibraon one, at the same dept and as close together as possible (fig. 3).
Always verify the range of the probes to be calibrated before using; the maximum temperature
of the probes should be higher then the temperature of the block otherwise the probe could
break.

DRUCK & TEMPERATUR Leitenberger GmbH: Page 8 of 24
- Advises:
The me the probes takes to reach the Set point is much more higher as the difference in
diameter from the probes and the holes is bigger.
Do not insert the probe when the instrument has already reached the set temperature; thermal
shock causes instability and breakage of the sensive element.
For the calibraon of temperature transducer with special execuon, call our technical office and
ask for equaliser block with special drillings.
REMEMBER TO SET UP AMBIENT TEMPERATURE AND LEAVE COOLING DOWN
BEFORE SWITCHING OFF THE CALIBRATOR

4 - SAFETY INSTRUCTIONS
ATTENTION:
Due to the fact that the calibrator is a portable instrument to be used in the field, it is
very important to ensure that the socket has been earthen correctly when connecng it
to the electricity supply.
Carry out the maintenance and repair operaon only with the equipment at ambient
temperature and disconnect the electrical cable.
During the use of the calibrator, the upper protecon grid may overheat.
Don’t touch the probe to calibrate when it’s in the block.
Aer using wait for the stabilisaon at ambient temperature before returning the
calibrator to its carrying case. Don’t switch off the calibrator when it works at high
temperature because the protecon grid and the carpentry may overheat.
Never put any type of liquid inside the block.
Don’t change absolutely the configuraon parameters.
Don’t put anything on the top of the calibrator.
Don’t put fuel object near the calibrator.
...... use common sense any me.
The equipment adopt the following devices to protect operaon from hazard:

6 - OPERATION PROCEDURE
6.1 - Operaon descripon
The PYROS-650 calibrator consist of a metal dry well with one hole of 26x150mm into which, the
inserts available for almost any sensor size to be calibrated, are inserted.
A heater element heats the block and an electronic µcontroller with stac relay output checks and
regulates the temperature.
A fan mounted in the central side generates a constant airflow that reduces the temperature of the
case.
6.2 - Descripon of instrument
6.2.1 - Thermo regulator
The thermo regulator (6) is a PID microprocesso 375/r, which can be set from 0 to 650°C. The display
indicates the temperature and the Set point (ref to item 10.1).
DISPLAY: indicaon of the temperature measured inside the block, set point selected and se ng
parameters .
56 KEY: used to increment (decrement) any numerical parameter. The increment (decrement)
speed is proporonal to the me the key remains depressed.
P KEY: allow access to the various parameters, access to the various phases of configuraon.
U KEY: allow access to the various group of parameters, access to the various phases of
configuraon or confirm the Set point.
6.2.2 - Main switch
The main switch (2) is on the rear of the instrument; it is fi ed with a socket for the voltage cable, a
main switch and two fuses as for the following table:
MODELS V230 V110/115
PYROS-375/650 3,15A 6,3 A
Note: use only fuses F. 5x20mm. All the electrical part is found below the main switch.
6.2.3 - Heang resistance
The resistance is stainless steel made; the max. power is 600W. and it can reach temperatures
approaching 375°C/650°C.
Bear in mind, however, that constant use at extreme temperatures reduces the life of the
resistance itself. Limit the number of hours at which the resistance is used at maximum
temperatures to the me required by the calibrator in order to prolong the life of the
resistance.
6.2.4 - Equalising block
The metal equalising block has an hole of 26mm where introduce the inserts far almost any sensor
size.
The funcon of this block is to make uniform the temperature on calibraon zone.
If you want to fit the calibrator with an insert wi th different holes we recommend to read the item 3.
This will avoid any unfortunate problems, which might arise if the wrong tolerances are used
Manu Basic 375 + PYROS Basical PYROS 650LR- LR-Cal Cal

DRUCK & TEMPERATUR Leitenberger GmbH: Page 13 of 24
6.2.5 - Temperature sensors
The temperature sensor used for the reading and thermoregulaon is a Thermocouple probe; the
probe is inserted directly into the equalising block so as to supply a temperature value close to the
real value in the block.
6.2.6 - Safety thermostat
The calibrator is supplied with a max. temperature safety thermostat with manual reset (11) that
disconnect the heang system.
In case the thermostat intervenes:
◊Waing the cooling of calibrator: the temperature must decrease at least 60÷80°C respect
to maximum set point (standard posion).
◊Switch off the calibrator then switch on again a few second later on.
◊If the problem persists: disconnect the electrical cable to the oven and proceeding to repair
of eventual faults (reference to paragraph 4). Consulng chapter 9 - typical faults - for any
problems on the thermostat.
N. B: the thermostat mounted on standard ovens has been calibrated in factory to intervene at
665°C±10°C.
6.3 - Start-up instrucons
ATTENTION:
The calibrator can only be used correctly if the user has a good knowledge of its basics.
Before starng with the calibraon following the installaon procedures (paragraph 5); read the
instrucon on paragraph 3 & 4.
To calibrate the probe it is possible to follow two ways: calibraon with internal indicator (6), or
calibraon with external reference.
A) Calibraon with the internal indicator):
Make reference to the temperature value of the display (6).
It is opportune to refer the value to the test report to compensate the error of the display.
B) Calibraon with external reference:
Make reference to the temperature value of the external standard instrument.
Put the sensive elements of the probes near and at the same dept (reference to fig. 1-2-3-5).
A
B
Manu Basic 375 + PYROS Basical PYROS 650LR- LR-Cal Cal

DRUCK & TEMPERATUR Leitenberger GmbH: Page 14 of 24
Before any calibraon follow the general recommendaon:
Switch on the calibraon with the main switch (2); waing for the end of self-test procedure.
Put the probe to check into the equaliser block: reference to chapter 3. (fig 1-2-3).
Set the required temperature value on the thermo regulator (reference to paragraph 10.1):
◊Press 6or P to adjust the Set Point.
◊Press the 5key to increment the set point value.
◊Press the 6key to decrement the set point value.
◊Push U for 3” or wait for 10” to confirm the Set Point.
If the temperature is lower than the Set Point the two red leds are on.
Wait for the stabilisaon of the oven before start with the calibraon.
For different calibraon point, regulate the set point at the new temperature and wait for the
stabilisaon.
The temperature indicated by the display must not be considered as a reference temperature
but only as a general indicaon of the temperature inside the block.
We suggest to insert one primary standard with SIT cerficate in the block; compare the
measure with the values indicated by the stan dard. Don't ever use the primary standard: it's
possible to calibrate the instrument to more significant points, comparing the displayed
temperature with that temperature of standard.
ATTENTION
At the end of the calibraon DO NOT remove the probe if it is sll at high temperature.
Always allow the calibrator to cool off with the probe sll inserted in order to avoid
thermal shock to the probe itself and harm to people or things.
Before returning the calibrator to its case make sure that the temperature of the block is
almost the same as ambient temperature.
-Cooling
To reduce the oven’s temperature, change the set point to 0°C and wait for the natural cooling.
6.4 - Use of the funcon
-Switchtest
You can test the operang point of the thermostats by the 'SWITCH TEST' funcon (4).
Put the thermostat in the most suitable hole of the block (see the note in paragraph 3).
Connect the terminals of the thermostat to the socket (4).
Switch on the calibrator.
Set the test temperature 5% lower to the operang temperature of the thermostat then increase
the Set Point one or two °C each me in order to switch Off/on the thermostat, the lamp (5) will
come on or Off when the thermostat electric contact works.
Set the test temperature lower to the operang temperature + the differenal of the thermostat,
the lamp (5) will come Off/on when the thermostat electric contact works.

NOW CONFIGURED FOR ALL THE SETPOINTS.
If you wish to disable this ramp, repeat this procedure from the start to re-access configuraon
SP.u parameter to inF then push U to exit.
During the rise in temperature with the ramp the lower display will change the value with the rate
you have set. The turning on or off of the lamp (5) idenfies the moment of triggering, at this
point note the value of the display (6) before se ng a lower temperature at the triggering point
of the thermostat, considering the differenal. During the fall in temperature check the
thermostat has intervened with the turning off or on of the lamp (5) and note the value of the
display (6), if the value set is not sufficient set a lower temperature. The two temperature values
recorded are equivalent to the trigger points of the thermostat, if necessary repeat the test two
or more mes to verify the repeatability of the thermostat.
6.5 - Re-calibraon methods
To have instrument always efficient is opportune to re-calibrate it periodically.
Frequency of re-calibraon is depending to the use of instrument; however we suggest to re-
calibrate instrument every year.
To re-calibrate instrument is necessary to have a standard temperature instrument with SIT
cerficaon.
CALIBRATION OF THE REGULATOR:
To calibrate the Pyros it is necessary a standard probe.
The parameters that allows to calibrate the Pyros650 are the following :

For example:
If you want to calibrate the Pyros to the values 50 and 500°C proceed in this steps:
insert a standard thermometer in the oven and set the set point of 50°C and
wait unl the oven is stable then read the value of the display of Pyros and the value of the
standard probe.
50= A.L.P value of the display of the Pyros.
48= value of the standard thermometer
Set a negave value of -2 to the value of the display in order to indicate the value of the Standard
reference.
Set the set point to 500°C and
wait unl the oven is stable then read the value of the display of Pyros :
500= A.H.P value of the display of the Pyros.
497= value of the standard thermometer
Set a negave value of -3 to the value of the display in order to indicate the value of the Standard
reference.
Set a Posive or negave Offset that is simply added to the value read by the probe before
visualizaon.
Set this values to correct the instrument
Par. Descripon value
130 A.L.P Adjust low point 50
131 A.L.o Adjust low offset -2
132 A.H.P Adjust high point 500
133 A.H.o Adjust high offset -3
Press and hold the “U” bu on for about 5 seconds to exit from Calibraon.
Now the calibraon is completed.
7 - MAINTENANCE INSTRUCTIONS
7.1 - Roune inspecons instrucons
Check that the holes of the calibrator are cleaned, any liquid or oil inside the hole could make
oxides or dirty during the use at high temperature.
Check once a year the calibraon date. Frequency of calibraon is depending to the use of
instrument; however we suggest to calibrate the instrument every year.
