1 - Introduction

T-30NIR-H

The Calibrator for Infrared Thermometer T-30NIR-H produces temperature values

in order to enable the calibration of infrared thermometers next to ambient temperature

which makes it suitable for calibrating forehead thermometers. The generated

temperatures have high accuracy. The calibrator also has a large area of known

emissivity and uniform temperature and is therefore compatible with target sizes of most

commercial infrared thermometers.

The calibrator also has an external probe input that makes it possible to control

the temperature from a standard thermoresistance sensor (optional) inserted in the

same measurement zone as the sensors under calibration, increasing accuracy and

decreasing setpoint errors and effects of block loading.

•The T-30NIR-H calibrator generates temperatures from 20 to 45 °C.

•The calibration curve of the standard sensor follows the Callendar -Van Dusen

parameterization.

•Has input for RTD.

•No use of external standard thermometer *.

•Performs automatic calibrations with or without the use of computers.

•Accuracy of up to 0.1 °C, 0.1 °C stability and resolution of 0.01 °C.

•Communication with computer and software ISOPLAN.

•Portable, compact, features handles and carrying case.

* For high performance calibration, it is possible to make use of an external sensor RTD

read in the input of the calibrator, with adjustment of the Callendar-Van Dusen

coefficients.

Has a wide variety of programming resources, where the calibrator is

programmed to generate pre-set temperatures. Compatible with automatic and

documented calibration programs, applying the ISOPLAN software on PC / Windows

platform, using the serial port for connection between the PC and the calibrator that

communicate via RS-232 or RS-485. With ISOPLAN software can register thermometers

2 - T-30NIR-H Calibrator Operation

The T-30NIR-H controls the temperature of the blackbody target and is suitable

for calibration of infrared thermometer.

The calibrator has 3 operating modes:

•Manual Mode to select the block temperature straight from the keypad.

•Programmable Mode: 6 different programs with 11 temperature set point values. The

block temperature is selected among the programmed values by the keys and.

The Programmable Mode with Timer scans automatically the temperature set points.

•Automatic Mode the calibration is performed in an automatic way by the calibrator: the

schedule and the calibration results, besides the object under calibration readings are

stored in the calibrator memory. For pyrometers with local indication, readings are

entered manually and for pyrometers with response in mA, V or thermocouple signal,

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. After the self-

test is completed, the display shows the starting menu.

2.1.2 - External Probe Connection

Insert the standard 4-wire Pt-100

sensor into the test block and fit its mini-

DIN connector to the external probe input

(EXT. PROBE) located on the front panel

of the thermal bath, as shown in the figure

below:

For the use of temperature control by the external probe, the function must be

enabled through the PRBe option of the PRG menu.

The consultation of the values of the steps of a program must be carried out using

the VARIABLE option, confirming the values shown onthe display with the ENTER key.

The options 10%,20% and 25% automatically change the number of steps and

recalculate their values using SETPOINT HIGH and SETPOINT LOW.

PRBe:This option allows you to enable the use of an external probe to control the

temperature of the thermal bath when selecting YES. To use the internal probe, select

NO. When the external probe is enabled, configure the calibration parameters in the

PARAM menu and the temperature unit in CF as degrees Celsius or Fahrenheit. The

calibration parameters correspond to the coefficients R0, A, B and C of the Callendar-

Van Dusen equation:

R (t) = R0 {1 + A.t + B.t2 + C.t3. (T -100 ºC)}, with C = 0 for t ≥ 0.

This equation is normally used on the IPTS -68 temperature scale, where t refers

to the temperature on this scale and R0, to resistance at 0 ºC. However, it can also be

used on the ITS-90 scale.

When entering the value of a coefficient, it must be separated into mantissa and

exponent as well as used in scientific notation. For a C coefficient of -3.151052 × 10-2,

for example, type your mantissa (an integer and fractional part of six digits) in the

mnemonic C and the exponent, in module, in the mnemonic E_C. Thus, we have C=

-3.151052 and E_C = 2.

It should be noted that the sign of a number can be inverted by pressing the

ZERO key when there is a null number on the display. This changes the + sign to -and

vice versa.

The coefficients for the ITS-90 scale according to the IEC -60751 standard are

shown below:

2.4 - Programable Operating Mode

Pre-configured programs can be loaded from the calibrator memory, enabling the

programmable operating mode. The temperature programmed values of the target are

used directly, with no need to enter the set point.

The display shows STEPn beside the target temperature set point value in the

programmable mode. The number of the program is indicated by n. Using the keys 

and , the programmed values of temperature set point are changed. The numeric

keypad continues available for manual selection of the temperature in the same way of

the manual operating mode.

The automatic scan over the programmed temperatures is implemented by

defining the stabilization time of the thermo-element.

The key enables the automatic scan over the points. When pressed, the

message STEPn gives place to 0s and the calibrator waits for the stabilization time

configured from 1 to 9 minutes, by the keys 1to 9. The automatic scan is disabled by

pressing key again.

A countdown of the stabilization time is only started when the temperature

reaches the programmed temperature and stabilizes within a range of approximately

2.5 - Automatic Operating Mode

The infrared thermometer calibration is performed in an automatic way by the T-

30NIR-H 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.

TAG EXEC VERIF

ADDRESS



TAGMAN

Before you start programming, first configure the signal that will be read by the

calibrator in the menu IN. To calibrate infrared thermometers with local indication, as an

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

thermometer, at the end of the stabilization time of each calibration point.

The data for an automatic calibration concern:

•TAG: the infrared thermometer tag identification.

•SP: the blackbody target temperature reference values for the calibration (calibration

points).

•TOL: the maximum tolerance for the infrared thermometer operation.

•STB: the stabilization time, in seconds, so that the thermometer temperature indicates

correctly. This timer starts just after the target 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 thermometer 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-30NIR-H calibrator.

The keypad does not work until the end of the calibration.

At the end of the stabilization time, the calibrator stores the thermometer 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

VERIF from menu COM.

The first message in option VERIF informs the calibration result, with the number

of points that have succeeded. Following, press ENTER to verify each one of the

automatically not using the ISOPLAN, there is a reserved place for one manual tag. The

selection of the manual tag is performed by confirming the option TAGMAN with the key

ENTER.

The option ADDRESS selects the communication address of the T-30NIR-H

calibrator. The communication protocol used is ModBus -RTU, with no parity and baud

rate of 9600. The calibrator communication with the computer can use RS-232 or

RS-485, for network option, according to the communication interface used. In order to

communicate with ISOPLAN software, configure ADDRESS to 1.

3 - Usage Recommendations

It is of great importance to know the instrument to be calibrated. Infrared

thermometers have characteristics that must be met for the results to be correct, as the

emissivity adjustment (if any), focal length and focus area, for example. These data are

easily obtained on the thermometer user manual and this observation is needed to verify

the compatibility between thermometers and calibrator.

The forehead infrared thermometer measures the surface temperature of the

human body and corrects the value, bringing the indication closer to the internal body

temperature. To perform the calibration of these thermometers, it is necessary to use it in

the surface measurement function. Refer to the forehead thermometer manual for how to

make this change.

To perform the readings, align the infrared thermometer with the blackbody target

horizontally. Observe the distance from the thermometer to the blackbody target,

respecting the size of effective target, as seen on thermometer user manual. Remember

that the area targeted by the infrared thermometer to be calibrated must be less or equal

to the blackbody target size in order to avoid introducing measurement errors.

The external sensor is an optional accessory that may be installed to increase the

accuracy of temperature indication. This sensor can be supplied with the Callendar-Van

Dusen parameters and configured in the Probe Input of T-30NIR-H calibrator.

5 - Calibration

Warning: Enter the following options only after understandingthem completely.

Otherwise, it may be necessary to return the instrument to the factory

for recalibration! In this manual, calibration means adjustment.

Select CAL option from the main menu and press the ENTER key. You should

then enter the password (PASSWORD) 9875 to access the calibration menu.

The password functions as a protection to calibration ranges. After the password

is entered, the menu displays the options:



IN OUT DATE

You should then choose the input range (IN) as the output range (OUT) is not

available for the user. DATE is an option which allows you to record the date on which

the calibration was performed and once it has been filled in, it will be displayed every

time the calibrator is turned on.

Options for IN calibration are:



mV OHM

5.1 - Input Calibration

The ohms/RTD input adjustment depends on the right adjustment of mV input.

Select the corresponding mnemonic and apply the signals presented in the tables

below.When calibrating inputs, the display shows on the 2nd line the value measured by

the calibrator and on the 1st line the same value is expressed as a percentage.

Note that the applied signals just need to be close to the values shown in the

table. Once the signal has been applied, store the values of the 1st and 2nd calibration

points, by pressing keys 1 (1st point) and 2 (2nd point).
