3 - GENERAL RECOMMENDATIONS
ATTENTION
The processor regulator has been configured in factory with the parameters suited to work in the
respect of the technical specifications.
Don’t change these parameters to avoid malfunction or breaking of the calibrator with risks of
serious personal injury.
- Position of the probe:
To obtain the best results, follow the advises:
Measure the diameter of the probe being checked.
Check that the diameter of the hole in the calibration block is
1. at least 0.5mm bigger than the diameter of the probe for diameter of the probe up to 8mm,
2. at least 0.7mm bigger than the diameter of the probe for diameter of the probe up to 12mm,
3. at least 0.5mm bigger than the diameter of the probe for diameter of the probe up to 8mm . If this is
not the case If this is not the case use the reduction wells with the above-mentioned tolerances
(fig.1).
Avoid using holes that 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 reduction insert using the tweezer
Insert the probe up to the bottom of the block: the sensitive element is in the optimal calibration zone (fig. 2).
Calibration with a reference: take care to position the two probes, the standard one and the calibration
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 internal temperature otherwise the probe could break
Fig.1 Fig.3Fig.2
PTB600-MAN-V10.4 PTB 600 Instruction Manual

- Advice:
The temperature difference is proportional to the difference between the diameter of the probe and the
diameter of the hole.
Do not insert the probe when the instrument has already reached the set temperature; thermal shock
causes instability and breakage of the sensitive element.
For the calibration of temperature transducer with special execution, call our technical office and ask for
equaliser block with special drillings.
REMEMBER TO SET THE AMBIENT TEMPERATURE AND LEAVE COOL THE
CALIBRATOR BEFORE SWITCHING OFF
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 connecting it to the power supply.
Carry out the maintenance and repair operation only with the equipment at ambient temperature
and disconnected from the electric power.
During the use of the calibrator, the upper protection grid may overheat.
Don’t touch the probe to calibrate when it’s in the block.
After using wait for the stabilisation 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 protection
grid and the carpentry may overheat.
Never put any type of liquid inside the block.
Don’t change absolutely the configuration parameters
Don’t put anything on the top of the calibrator.
Do not connect any voltage higher then 5V to the input 4-5-15
Don’t put fuel objet near the calibrator.
...... use common sense any time.
The equipment adopt the following devices to protect operation from hazard:
Max. temperature safety thermostat (10) to disconnect the heating system.
Protection grid to avoid any contact with the internal oven.
Protection fuses (3)
Ground conductor.

6 - OPERATION PROCEDURE
6.1 - Operation description
The PTB600 calibrator consist of an anticorodal block fitted with holes into which the sensors to be calibrated
are inserted.
A heater element heats the block and an electronic μcontroller with Triac output checks and regulates the
temperature.
A fan mounted in the rear side generates a constant air flow that reduces the temperature of the case.
6.2 - Description of instrument
6.2.1 - Thermoregulator
The thermo-regulator (7) is a PID microprocessor, which can be set from 0 to 550°C.(600 for model BA)
DISPLAY UPPER LINE: indication of the temperature measured inside the block.
DISPLAY LOWER LINE: indication of the set point; external probes if selected, setting parameters .
KEY: used to increment (decrement) any numerical parameter. The increment (decrement) speed is
proportional to the time the key remains depressed.
F KEY: allow access to the various parameters (repeatedly press), access to the various phases of
configuration (press F +).
E KEY: allow confirming the set parameter.
The calibrator is endowed with eight terminals (optional) that can be set as Pt100 or Tc.
6.2.2 - Main switch
The main switch (2) is fitted with a socket for the voltage cable, the main switch and two fuses as for the
following table:
MODEL V230 V110/115
PTB600-TC
PTB600-TS
5A 10A
Note: use only fuses F. 5x20mm. All the electrical part is found below the main switch.
6.2.3 - Carrying handle
The calibrator is fitted with a carrying handle .
6.2.4 - Heating resistance
The resistance (13) is stainless steel made; the max. power is 800W (1200W for the ¢65, 230V models)
and it can reach temperatures approaching 600°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 time required by
the calibrator in order to prolong the life of the resistance.
PTB600-MAN-V10.4 PTB 600 Instruction Manual
13
6.2.5 - Equalising block
The function of the block is to make the temperature uniform on calibration zone.
If you want to fit the calibrator with a block with different holes we recommend that you should contact the
technical support department who will check to see if it is feasible. This will avoid any unfortunate problems
which might arise if the wrong tolerances are used. The equalization block is in aluminium, Aluminium-
Bronze or Copper depending on the models; holes have been made on the inside to make it possible to fit
various types of probes.
6.2.6 - Temperature sensors
The temperatures sensor used for regulating is a Pt100 and the temperature sensors used to protect the
instrument is a thermocouple.. Both are inserted directly into the equalization block so as to supply a
temperature value close to the real value in the block. There could, however, be some differences due to the
tolerances of the sensors themselves.
6.2.7 - Safety thermostat
The calibrator is supplied with max. temperature safety thermostat (10) that disconnect the heating system.
In case the thermostat intervenes:
Waiting the cooling of calibrator: the temperature must decrease at least 60÷80°C respect to maximum
set point.
Switch off the calibrator then switch on again a few second later on.
If problem persist: disconnect the electrical cable to the oven and proceeding to repair of eventual faults
(reference to paragraph 4); therefore switch on the oven. Consulting 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 560 or 610°C
±5°C depending on the models.

6.3 - Start-up instructions
ATTENTION:
The calibrator can only be used correctly if the user has a good knowledge of its basics.
Before starting with the calibration following the instructions for the positioning of the equalising block
(paragraph 5); carefully read paragraph 3 and 4.
To calibrate the probe it is possible to follow two ways: calibration with internal indicator (7), or calibration
with external reference.
Calibration with the internal indicator (7):
Make reference to the temperature value of the display (7:
fig.4).
It is opportune to refer the value to the test report to
compensate the error of the display.
Calibration with external reference and reading on the
calibrator display:
Make reference to the temperature value of the external
standard instrument inserted in the equalizer block and
connected directly to the Solar (Fig.5); temperature is read
on the second line of display (for the configuration of the
external reference seeing 10.1). When possible: put the
sensitive elements of the probes near and at the same dept
(reference to Fig.1-3)
Calibration with external reference and reading on an
external instrument:
Make reference to the temperature value of the external
standard instrument inserted in the equalizer block and
connected to an external instrument (Fig. 5). When
possible: put the sensitive elements of the probes near and
at the same dept (reference to fig.1-3).
Fig.4
Fig.5
PTB600-MAN-V10.4 PTB 600 Instruction Manual
15
Before any calibration follow the general recommendation:
Starting the calibration only at ambient temperature: thermal shock can break the sensitive element of the
probe and cause harm to operator.
To fit the equaliser block inside the oven: reference to paragraph 5.1.4.
Put the probe to check into the equaliser block: reference to chapter 3 (fig 1-3).
Push on the main switch (2) and waiting for the end of autotest procedure.
Set the required temperature value on the set point following the instructions below:
Press the
key to increment the set point value.
Press the
key to decrement the set point value.
Press the E key to confirm
Wait for the stabilisation of the oven before starting any calibration (symbol ÷ on the first line of the
display).
To working at different temperatures set the set point at the new value and wait for the stabilisation.
When the set point is changed, the temperature read on the display and that measured in the block may
not proceed at the same speed; this is because there are differences between the sensors used and the
position of the same inside the block.
The temperature indicated by display must not be considered as a reference temperature but only as a
general indication of the temperature inside the block.
We suggest to insert a primary standard in the block; compare the measure with the values indicated by
the standard.
Don't ever use the primary standard: it's possible to calibrate the instrument to more significant points,
comparing the displayed temperature with the temperature of the primary standard.
ATTENTION:
At the end of the calibration DO NOT remove the probe if it is still at high temperature. Always
allow the calibrator to cool off with the probe still inserted in order to avoid thermal shock to the probe
itself and harm to people or things.
Before switch off the calibrator 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 and wait for the cooling.

DESCRIPTION OF REGULATOR’S MENU
The calibrator has three menu levels( see image 10.2):
at the first level there are the functions for the continuous usage,
at the second level there are more specific functions for the regulation of the calibrator,
at the third level there are the typical functions for each calibrator and the calibration procedures.
1st MENU LEVEL
PRESS THE FKEY TO STEP THROUGH THE MENU
- SP
SET POINT: temperature set which the oven has to reach following technical specifications, press the
or key to adjust the set point and press E key to accept new the new value.
- SP2
SET POINT2: temperature set which the oven reaches with the set gradient and the ongoing launched
ramp procedure, press the or key to adjust the set point and press E key to accept new the new
value.
- GRAD
GRADIENT: set point variation speed during the change from one temperature value to the SP2 value,
press the or key to adjust the set point and press E key to accept new the new value.
The set gradient must be negative for descent ramps.
NOTE: gradient values to be set must be lower than the ones stated in the technical data, at point 2.2
(cooling grad. max.: -7°C/min.; heating grad. max. 18°C/min).
- RAMP
Ramp procedure enabling/disabling.
Select ON or OFF by the or key and press E key to accept; the oven will reach the set SP2
temperature with the set gradient, starting from the same temperature as the one with which the ramp
has been confirmed. The starting temperature does not depend on the Set Point temperature.
If a negative ramp is set put the gradient is left positive and/or the SP2 is higher than the current
temperature, the little over will not accept the ramp start and an alarm will begin running.
When the ramp is on, the display will show the word "Ramp:......." followed by the Set Point value on the
second line of the text. The Set Point value will reach the speed related to the set gradient.
When the block temperature reaches the SP2 set temperature, the oven will produce an alarm and the
ramp procedure will be automatically set off; the SP2 value will be considered as the new set point value
and the oven will be steadily set at that temperature.
During the ramp process, the derivative parameter will not be considered.
RAMP PROCEDURE EFFECTIVE EXAMPLE
Let’s say that the set temperature is the ambient one and that it is necessary to reach 400°C with a
gradient of 2°C/min.
- Press the F key and set SP2 to 400°C using the or keys. Press the Ekey to accept.
- Press the Fkey and set GRAD to 1°C/min using the or keys. Press the Ekey to accept.
- Press the Fkey and set RAMP to ON using the or keys. Press the Ekey to accept.
After pressing the E key to confirm the ramp start, the oven temperature will ascend with the set slope.
Of course, there will be some oscillations at the beginning since the ramp slope will not be suitable but
they will stop in a short time and then the oven temperature will follow the ramp’s set point.
- RIS. 0.1/0.01
Display reading resolution; Press the or key to select 0,1 or 0,01 and press E key to accept.
- SW. ON
Switch on; displays the temperature at which the thermostat connected to the terminals "SWITCH TEST"
is closed.
