2 Introduction 2 Introduction The Hart Scientific 9009 Industrial Dual-Block Calibrator may be used as a portable instrument or bench top temperature calibrator for calibrating thermocouple and RTD temperature probes. The 9009 is small enough to use in the field, and accurate enough to use in the lab. Calibrations may be done over a range of –15°C to 350°C (5°F to 622°F). Temperature display resolution of the 9009 is 0.1 degrees.

4 Quick Start Unpacking 4 4.1 Quick Start 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: • 9009 Dry-well • Two 3102-3 ( 3/16”) and two 3102-4 (1/4”) Inserts • Power Cord • Report of Calibration with calibration label • User’s Guide • 9930 Interface-it Software and User’s Guide • RS-232 Cable • Insert Removal Tool 4.
9009 Industrial Dual-Block Calibrator User’s Guide requirements. Turn the calibrator on using the “POWER” switch on the power entry module (PEM). The calibrator will turn on and begin to heat or cool to the previously programmed temperature set-point. The front panel LED displays will indicate the actual calibrator temperature. 4.4 Setting the Temperature Section 7.2 explains in detail how to set the temperature set-point on the calibrator using the front panel keys. The procedure is summarized here.
5 Parts and Controls Top Panel (Lid Open) 5 Parts and Controls The user should become familiar with the dry-well calibrator and its parts. 5.1 Top Panel (Lid Open) Figure 1 Top Panel (Lid Open) Power Switch - The power switch is located on the power entry module (PEM). The PEM also houses the fuse. Power Cord - The removable power cord inlet plugs into an IEC grounded socket on the PEM. Insert Storage - Four inserts may be stored here.
9009 Industrial Dual-Block Calibrator User’s Guide Serial Port - A three-conductor jack is present for interfacing the calibrator to a computer or terminal with serial RS-232 communications. Controller Display - The digital display is an important part of the temperature controller because it not only displays set and actual temperatures but also various calibrator functions, settings, and constants. The display shows temperatures in units according to the selected scale °C or °F.
5 Parts and Controls Accessories 5.3 Accessories The following inserts are available for the 9009 calibrator. Inserts may be used with either the hot or cold temperature wells.

6 General Operation Changing Display Units 6 6.1 General Operation Changing Display Units The 9009 can display temperature in Celsius or Fahrenheit. The temperature units are shipped from the factory set to Celsius. To change to Fahrenheit or back to Celsius there are two ways: 1-Press the “SET” and “UP” simultaneously. This will change display units. Or 1-Press the “SET” button three times from the temperature display to show Un= C 2-Press the “UP” or “DOWN” button to change units.
7 Controller Operation Well Temperature 7 Controller Operation This chapter discusses in detail how to operate the calibrator 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.

9009 Industrial Dual-Block Calibrator User’s Guide Un= F New units selected Press “SET” to accept the present setting and to continue. 7.3 Scan The scan rate can be set and enabled so that when the set-point is changed the calibrator heats or cools at a specified rate (degrees per minute) until it reaches the new set-point. With the scan disabled the calibrator heats or cools at the maximum possible rate. 7.3.
7 Controller Operation Secondary Menu 7.4 Secondary Menu Functions which are used less often are accessed within the secondary menu. The secondary menu is accessed by pressing “SET” and “EXIT” simultaneously and then releasing. The first function in the secondary menu is the heater power display. (See Figure 3 on page 20.) 7.5 Heater Power The temperature controller controls the temperature of the well by pulsing the heater on and off.
9009 Industrial Dual-Block Calibrator User’s Guide set-point. This range of temperature is called the proportional band. At the bottom of the proportional band the heater output is 100%. At the top of the proportional band the heater output is 0. Thus as the temperature rises the heater power is reduced, which consequently tends to lower the temperature back down. In this way the temperature is maintained at a fairly constant temperature.
7 Controller Operation Controller Configuration S 7.7 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. These are accessed from the secondary menu after the proportional band function by pressing “SET”.
9009 Industrial Dual-Block Calibrator User’s Guide 7.9.1 BAUD Rate The BAUD rate is the first parameter in the menu. The BAUD rate setting determines the serial communications transmission rate. bAUd 2400 b Flashes and then displays the current setting Current BAUD rate setting The BAUD rate of the serial communications may be programmed to 300, 600, 1200, 2400 (default), 4800, or 9600 BAUD. Use “UP” or “DOWN” to change the BAUD rate value.
7 Controller Operation Calibration Parameters The mode may be changed using “UP” or “DOWN” and pressing “SET”. d=HALF 7.9.4 New duplex mode setting Linefeed The final parameter in the serial interface menu is the linefeed mode. This parameter enables (on) or disables (off) transmission of a linefeed character (LF, ASCII 10) after transmission of any carriage-return.
9009 Industrial Dual-Block Calibrator User’s Guide parameter to the new value. Pressing “EXIT” causes the parameter to be skipped ignoring any changes that may have been made. 7.10.1 R0 This probe parameter refers to the resistance of the control probe at 0°C. The value of this parameter is set at the factory for best instrument accuracy. 7.10.2 ALPHA This probe parameter refers to the average sensitivity of the probe between 0 and 100°C.
8 Digital Communication Interface Serial Communications 8 Digital Communication Interface 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.
9009 Industrial Dual-Block Calibrator User’s Guide 8.1.2 Setup Before operation the serial interface must first be set up by programming the BAUD rate and other configuration parameters. These parameters are programmed within the serial interface menu. The serial interface parameters menu is outlined in Figure 3 on page 20. To enter the serial parameter programming mode first press “EXIT” while pressing “SET” and release to enter the secondary menu. Press “SET” until the display reads “Par”.
8 Digital Communication Interface Interface Commands 8.1.3 Serial Operation Once the cable has been attached and the interface set up properly the controller immediately begins transmitting temperature readings at the programmed rate. The serial communications uses 8 data bits, one stop bit, and no parity. The set-point and other commands may be sent via the serial interface to set the temperature set-point and view or program the various parameters. The interface commands are discussed in Section 8.2.

9 Test Probe Calibration Calibrating a Single Probe 9 Test Probe Calibration For optimum accuracy and stability, allow the calibrator to warm up for 10 minutes after power-up and then allow adequate stabilization time after reaching the set-point temperature. After completing operation of the calibrator, allow the well to cool by setting the temperature to 25°C for one-half hour before switching the power off. 9.

10 Calibration Procedure Calibration Points 10 Calibration Procedure Sometimes the user may want to calibrate the instrument to improve the temperature set-point accuracy. Calibration is done by adjusting the controller probe calibration constants R0 , ALPHA, DELTA, and BETA (cold side) so that the temperature of the calibrator as measured with a standard thermometer agrees more closely with the set-point.
