1.4 - Instructions for the use of Black Body Insert
Identify the following parts and proceed to the mounting as explained:
Cylindrical Thermal insulator –Mounted in the lower part of the pit of the
furnace.
Metallic insert type black body cavity –Must be introduced in the pit joined with
a thermocouple type N mounted laterally.
Careful when introducing the thermocouple in the cavity to not force the fragile
ceramic wall pit.
Ring-shaped cylindrical Insulator - mounted on top of the pit of the furnace
Note that the position of the slit of insulation should match the type N
thermocouple sheath laterally.
Connect the terminals of the thermocouple type N to the auxiliary input side of
the furnace T-1200PIR and set the reading of the IN input to N type
thermocouple.
The combination constitutes an excellent mounted cavity black body with
emissivity above 0.95 and an effective target of Ø 20 mm well suited for calibration of
pyrometers.
Align the pyrometer to be calibrated with a black body cavity in the furnace in a
horizontal position.
Observe the distance of the pyrometer to be calibrated against the background
of the black body cavity and the size of the actual target (Ø 20 mm) as specified in the
technical manual optical pyrometer.
Remember that the area targeted by the pyrometer to be calibrated must be
less than or equal to the effective target spot size of the black body in order to not
introduce measurement errors.

2.0 - T-1200PIR Calibrator Operating
The T-1200PIR calibrator keeps controlled the temperature of the black body
cavity and is suitable for calibration of infrared thermometers.
The calibrator has 3 operating modes:
Manual Mode to select the temperature straight from the keypad
Programmable Mode: 6 different programs with 11 temperature set point values. The
cavity temperature is selected among the programmed values by the keys and.
The Programmable Mode with Timer scans automatically the temperature set points.
Automatic Mode calibration is performed in an automatic way by the calibrator: the
schedule and the calibration results, besides the thermo-element readings are stored
in the calibrator memory. For pyrometers with local indication, the reading is entered
manually and for pyrometers with response in mA, mV or thermocouple, reading is
performed automatically by the input of the calibrator.
When powered on (ON/OFF key), the calibrator goes through a self-test routine
and shows the last calibration date and the value of the battery voltage. The battery
voltage is constantly monitored and the low battery warning is provided. After the self-
test is completed, the display shows the starting menu. The initial set point is 50.00 ºC.

SC: This function scales the input reading of pyrometric transmitters. The
scaling is very useful in temperature transmitter calibration, for instance, because it
displays the current temperature and the transmitter reading in the same unit. Thus,
the error can be verified directly in ºC or ºF. Select the option SC and press ENTER. If
no input is selected in IN, the calibrator will show the SELECT INPUT FIRST message.
In this case, go to menu IN and select the input signal type.
The function SC will show IN or NO. Confirm IN to configure the scaling or NO
to disable the SC function, with the key ENTER.
The scaling is performed via the INPUT HIGH and INPUT LOW parameters,
corresponding to the maximum and minimum values of the calibrator signal input, in
the engineering unit of this signal. Next, configure the SCALE DEC (0-4),SCALE
HIGH and SCALE LOW parameters according to the maximum and minimum values
of the transmitter scale and the desired number of decimals. The scaled value is
shown on the display with the #unit.
For example, temperature transmitter with 0 to 100 ºC input and 4 to 20 mA

2.5 - Automatic Operating Mode
The thermo-element calibration is performed in an automatic way by the
T-1200PIR calibrator. The configuration, as well as the calibration verification is carried
out by the calibrator itself. Also it is possible to use the ISOPLAN software and its work
orders, like a CAC - Computer Aided Calibration.
The independent automatic calibration, without the use of ISOPLAN, is planned
in the option TAGMAN from menu COM.

Before start programming, configure the signal that will be read by the calibrator
in the menu IN. To calibrate pyrometers with local indication, for example, there is no
electric signal to be read. In this case, option IN from the menu must be configured to
NO and the calibrator will ask to enter the value indicated by the pyrometer, at the end
of the stabilization time of each calibration point.
The data for an automatic calibration are:
TAG: the pyrometer tag identification.
SP: the black body cavity temperature reference values for the calibration
(calibration points).
TOL: the maximum tolerance for the pyrometer operation.
STB: the stabilization time, in seconds, so that the pyrometer reading can be taken.
This timer starts just after the cavity reaches and stabilizes at the set point
temperature.
STR: the calibration strategy of the programmed reference values. The available
strategies are: (UP), (DOWN),  (UP - DOWN),  (DOWN - UP), 
(UP - DOWN - UP) and  (DOWN - UP - DOWN).
RP: the strategy number of repetitions.
RGI: the pyrometer indication range.
RGO: the operating temperature range that corresponds to the indication range
above.
The automatic calibration begins when the option EXEC from menu COM is
selected. All the operations are automatically performed by the T-1200PIR calibrator.
The keypad does not work until the end of the calibration.
At the end of the stabilization time, the calibrator stores the pyrometer reading in
memory and goes to the next point, in case some input signal has been previously
configured in the menu IN and connected to the calibrator terminals.
The CALIBRATION END message appears on the display at the end of the
automatic calibration. Press ENTER to confirm. The results can be verified in option

3.0 - Usage Recommendations
It is of great importance to know the instrument to be calibrated. Infrared
thermometers have characteristics which must be met so that the observed results are
correct, as setting of emissivity (if any), focal length and focus area,e.g.These data are
easily obtained in the thermometer user manual and this observation is needed to
prove the compatibility of thermometers with the calibrator.
To perform the readings, align the pyrometer with the black body cavity
horizontally. Respect the distance from the pyrometer to be calibrated in relation to the
black body cavity to the size of the actual cavity as pyrometer manual.Remember that
the area focused by the pyrometer to be calibrated must be less than or equal to the
black body cavity size in order to not introduce measurement errors.
The external sensor can be used to increase the accuracy of temperature indication.
4.0 - Safety Instructions
Do not leave the place where the calibrator is on without identification and warnings.
Before turning off the calibrator, return temperature black body cavity for values
close to ambient temperature.

6.0 - PID Control Parameters
The T-1200PIR calibrators have a PID control algorithm to calculate the
temperature control output.
The black body cavity stability and response time features are related to the PID
parameters, explained below:
The Kparameter (proportional gain) amplifies the error signal between the set
point and the cavity temperature to establish the output signal. When this parameter is
very high, the output reaction is very quick; however this can take the system into
oscillation. Decreasing this parameter, the cavity would not be able to react quickly
enough to external variations, giving the impression of a sudden out of control.
The Iparameter (integral gain) is responsible for the integral action and it is the
most important part in the set point control. While an error persists between the set
point and the cavity temperature, the integral action will actuate on the output signal
until the error is brought to zero.
The Dparameter (derivative gain) is responsible for the derivative action that
provides a quick response at the control output resulting from any rapt variation in the
cavity temperature. It is used to eliminate oscillations. However, it can cause
oscillations in the presence of much noise.
All temperature calibrators are tuned in factory and the parameters are close to
the optimum ones. In case one wants to improve a specific feature of the calibrator
(stabilization time or response time, for instance), make sure the alteration is made
reasonably.
