1 Before You Start 1 Before You Start 1.1 Introduction The Hart Scientific 9132 Portable IR Calibrator may be used as a portable instrument or bench top temperature calibrator for calibrating point IR thermometers. The 9132 is small enough to use in the field, and accurate enough to use in the lab. Calibrations may be done over a range of 50°C to 500°C (122°F to 932°F). Temperature display and setability resolution of the 9132 is 0.1 degrees.

9132 Portable IR Calibrator User’s Guide NOTE: As the calibrator temperature increases, the difference between the temperature sensed by the reference thermometer and the temperature of the face of the target increases. 2.2 Environmental Conditions Although the instrument has been designed for optimum durability and trouble-free operation, it must be handled with care. The instrument should not be operated in an excessively dusty or dirty environment.
3 Quick Start 3 Quick Start 3.1 Unpacking Unpack the calibrator carefully and inspect it for any damage that may have occurred during shipment. If there is shipping damage, notify the carrier immediately. Verify that the following components are present: ● ● ● ● ● 3.2 9132 Calibrator Power Cord User’s Guide Serial Cable 9930 Software Set Up Place the calibrator on a flat surface with at least 6 inches of free space around the instrument.
9132 Portable IR Calibrator User’s Guide When the set-point temperature is changed the controller switches the well heater on or off to raise or lower the temperature. The displayed well temperature gradually changes until it reaches the set-point temperature. The well may require 5 to 10 minutes to reach the set-point depending on the span. Another 5 to 10 minutes is required to stabilize within ±0.1°C of the set-point. Ultimate stability may take 15 to 20 minutes more of stabilization time.
4 Parts and Controls 4 Parts and Controls The user should become familiar with the calibrator and its parts. 4.1 Back Panel The back panel (Figure 2) consists of the power cord inlet, power switch, heater voltage switch, serial port, and fan.
9132 Portable IR Calibrator User’s Guide Fan – The fan inside the calibrator has two speeds and runs continuously when the unit is being operated to provide cooling for the instrument. The fan runs slow for heating and maintaining operation and runs fast for rapid cooling. Slots are provided for airflow. The area around the calibrator must be kept clear to allow adequate ventilation. The airflow is directed out the front and can be extremely hot. 4.
4 Parts and Controls UP – Used to increment the displayed value. EXIT – Used to exit a function and to skip to the next function. Any changes made to the displayed value are ignored. Target Assembly – The target assembly is 57 mm (2.25 in) in diameter and has an emisivity of 0.95.
5 General Operation 5 General Operation 5.1 Changing Display Units The Model 9132 can display temperature in Celsius or Fahrenheit. The temperature units are shipped from the factory set to Celsius. There are two ways to change to Fahrenheit or back to Celsius as described below. 1. Press the “SET” and “UP” simultaneously. The units are changed. Or 1. Press the “SET” key three times from the temperature display to show Un = C 2. Press the “UP” or “DOWN” key to change units. 5.
6 Controller Operation 6 Controller Operation This chapter discusses in detail how to operate the instrument temperature controller using the front control panel. Using the front panel key-switches and LED display the user may monitor the well temperature, set the temperature set-point in degrees C or F, monitor the heater output power, adjust the controller proportional band, and program the calibration parameters, operating parameters, and serial interface configuration.

9132 Portable IR Calibrator User’s Guide Press “SET” to accept the present setting and continue. S 6.4.2 Accept scan setting Scan Rate The next function in the main menu is the scan rate. The scan rate can be set from .1 to 99.9°C/ min. The maximum scan rate however is actually limited by the natural heating or cooling rate of the instrument. This is often less than 100°C/min, especially when cooling. The scan rate function appears in the main menu after the scan control function.
6 Controller Operation The heater power display is accessed in the secondary menu. Press “SET” and “EXIT” simultaneously and release. The heater power is displayed as a percentage of full power. 100.0 C Well temperature S+E Access heater power in secondary menu SEC Flashes “SEC” for secondary menu and then displays the heater power 12.0P Heater power in percent To exit out of the secondary menu press and hold the “EXIT” button. To continue on to the proportional band setting function press “SET”.

Press “EXIT” to continue without storing the new value. S 6.10 Accept the new proportional band setting Controller Configuration The controller has a number of configuration and operating options and calibration parameters, which are programmable via the front panel.
6 Controller Operation 6.12.1 Baud Rate The baud rate is the first parameter in the menu. The baud rate setting determines the serial communications transmission rate. bAUd Flashes bAUd and then displays the setting 2400 b Current baud rate The baud rate of the serial communications may be programmed to 300, 600, 1200, 2400, 4800, or 9600 baud. Use “UP” or “DOWN” to change the baud rate value.
LF Flashes LF and then displays the setting LF= On Current linefeed setting Adjust the setting using “UP” or “DOWN” and pressing “SET”. LF=OFF 6.13 New linefeed setting Calibration Parameters The operator of the instrument controller has access to a number of the calibration constants namely R0, ALPHA, and DELTA. These values are set at the factory and must not be altered. The correct values are important to the accuracy and proper and safe operation of the instrument.
7 Digital Communications 7 Digital Communications The calibrator is capable of communicating with and being controlled by other equipment through the digital serial interface. With a digital interface the instrument may be connected to a computer or other equipment. This allows the user to set the set-point temperature, monitor the temperature, and access any of the other controller functions, all using remote communications equipment. Communications commands are summarized in Table on page . 7.
9132 Portable IR Calibrator User’s Guide 7.2.1.1 Baud Rate The baud rate is the first parameter in the menu. The display prompts with the baud rate parameter by showing “bAUd”. Press “SET” to choose to set the baud rate. The current baud rate value is displayed. The baud rate may be programmed to 300, 600, 1200, 2400, 4800, or 9600 baud. The baud rate is pre-programmed to 1200 baud. Use “UP” or “DOWN” to change the baud rate value.
7 Digital Communications is sent with the command following a “=”. For example, “s=150.0” sets the set-point to 150.0 degrees. In the following list of commands, characters or data within brackets, “[” and “]” are optional for the command. A slash, “/”, denotes alternate characters or data. Numeric data, denoted by “n”, may be entered in decimal or exponential notation. Characters are shown in lower case although upper case may be used. Spaces may be added within command strings and will simply be ignored.

8 Calibration Procedure 8 Calibration Procedure Sometimes the user may want to calibrate the instrument to improve the temperature setpoint accuracy. Calibration is done by adjusting the controller probe calibration constants R0, ALPHA, and DELTA so that the temperature of the dry-well as measured with a standard thermometer agrees more closely with the set-point. The thermometer used must be able to measure the well temperature with higher accuracy than the desired accuracy of the dry-well.

Where: T1 and R1 are the measured temperature and resistance at 50.0°C T2 and R2 are the measured temperature and resistance at 200.0°C T3 and R3 are the measured temperature and resistance at 350.0°C 8.2.
8 Calibration Procedure 8.2.3 Accuracy and Repeatability Check the accuracy of the instrument at various points over the calibration range. If instrument does not pass specification at all set-points, repeat the Calibration Procedure.
