CHAPTER INTRODUCTION AND SPECIFICATIONS Installation 1 Installation This section describes the procedures for installing and removing a TCM-39032 module from the LDC-3900. Note: The LDC-3900 will power up in a default state upon detecting any change in the LDC-3900 system configuration (such as installing a new module). All parameters (except SAVE / RECALL settings) will be set to default values, based on the new configuration.
CHAPTER 2 OPERATION This section describes the procedures for connecting and running a temperature controlled laser diode with the TCM-39032 module.
CHAPTER 2 OPERATION SENSOR SELECT Switches SENSOR SELECT Switches The SENSOR SELECT and THERM RANGE switches are used to select sensor type and, in the case of thermistor sensor, the source current level. Table 2.1 shows the SENSOR SELECT ( THERM RANGE) positions and corresponding position code. When the sensor switch is changed during TEC mode operation, the new sensor position code will be indicated on the TEC display for three seconds.
OPERATION TEC Connector CHAPTER 2 TEC Connector At the right of center, on the TCM-39032 back panel, the user will find the 15-pin D-connector for the TEC MODULE. This connector is used for the input and output connections, as shown by the pin-out diagram below. 1, 2 3, 4 5 6 7 8 9 10 11 12 13 14 15 TE Module (+) TE Module (-) TE Module Shield Sensor Shield Sensor (+) Sensor (-) Analog Ground Control Signal Voltage Limit Current Limit Temp.
CHAPTER 2 OPERATION Booster Operation present, the TEC Interlock Error condition / event will be reported in the TEC Event Status REgister and the TEC Condition Status Register. This circuit is useful for remote monitoring of temperature, and therefore is labeled TEMP LIMIT on the back panel connector. This interlock is intended for use with an external current booster. A switch or control circuit of the user’s own design is required. It is left as an option which the user may or may not employ.

CHAPTER 3 CALIBRATION The TCM-39032 should be calibrated every 12 months or whenever performance verification indicates that calibration is necessary. All calibrations can be done with the case closed. The instrument is calibrated by changing the internally shored digital calibration constants. Recommended Equipment Recommended test equipment for calibrating the TCM-39032 is listed in the table below.
CHAPTER CALIBRATION Environmental Conditions 3 Environmental Conditions Calibrate this instrument under laboratory conditions. ILX recommends calibration at 23 oC + 1.0 oC. When necessary, however, the LDC-3900 Modular Laser Diode Controller may be calibrated at its intended use temperature if this is within the specified operating temperature range of 0 to 50 oC. Warm Up The LDC-3900 should be allowed to warm up for at least 1 hour before calibration.
CALIBRATION TEC Calibration Procedures CHAPTER 5 Press and hold the (PARAMETER) SET switch and turn the ADJUST knob until the TEC display indicated the same resistance recorded for the metal film resistor. 6 Release the (PARAMETER) SET switch to store the new value into non-volatile memory on the TCM-39032. After the (PARAMETER) SET switch is released, the LDC-3900 will beep and return to its former state (before calibration).
CHAPTER CALIBRATION TEC Calibration Procedures 3 the GPIB hardware. Refer to the GPIB manual for details. 7 Switch the THERM RANGE switch (back panel) to the 10 µA position and repeat this procedure with the other resistor. Local Operation AD590 Sensor Calibration The following procedure is for calibrating the AD590 sensor so that the temperature measurement will be as accurate as possible. This procedure is for local (front panel) operation.
CALIBRATION TEC Calibration Procedures CHAPTER 3 If this value is to be measured and entered remotely via a GPIB controlled DMM, for example, the measured value of the current should not be entered until the LDC-3900 is ready to receive it. The LDC-3900 will be ready to receive the current value when, after a “TEC:CAL:SENsor?” query is sent, the response from the LDC-3900 is “1”. After the “TEC:R” value is entered, the “*OPC?” query may be used to determine when the calibration sequence is done.
CHAPTER CALIBRATION TEC Calibration Procedures 3 Remote Operation LM335 Sensor The following procedure is for calibrating the LM335 sensor so that the temperature measurement will be as accurate as possible. This procedure is for remote operation. 1 Set the SENSOR SELECT switch (back panel) to the LM335 position (position --03). 2 Connect a precision 6.8 KΩ (metal film) resistor and a precision voltmeter in parallel at the sensor input of the TCM-39032 (pins 7 and 8).
CALIBRATION TEC Calibration Procedures CHAPTER 3 Local Operation RTD Sensor Calibration (with TSC-595 Option) The following procedure is for calibrating the RTD sensor so that the temperature measurement will be as accurate as possible. This is a two-point calibration procedure. This procedure is for local (front panel) operation. The next section will cover remote calibration. 1 Set the SENSOR SELECT switch (back panel) to the RTD position (position --05).
CHAPTER CALIBRATION TEC Calibration Procedures 3 Remote Operation RTD Sensor Calibration (with TSC-595 Option) The following procedure is for calibrating the RTD sensor so that the measured temperature will be as accurate as possible. This procedure is for remote operation. 1 Set the SENSOR SELECT switch (back panel) to the RTD position. 2 Measure and record the exact resistance of a 120 Ω (metal film) resistor. (A 4-point probe resistance measurement is recommended.
CALIBRATION TEC Calibration Procedures CHAPTER 3 Local Operation ITE Current Calibration The following procedure is for calibrating the ITE constant current source for both polarities of current. This procedure calibrates the zero current set point automatically, then it automatically drives the TE current output to internally set limits of +1 amp. When each of these values is reached and is stable, the user enters the actual value of the current, as measured by an external DMM.
CHAPTER CALIBRATION TEC Calibration Procedures 3 Remote Operation ITE Current Calibration The following procedure is for calibrating the ITE constant current source for both polarities of current. This procedure calibrates the zero current set point automatically, then it automatically drives the TE current output to internally set limits of +1 amp. When each of these values is reached and is stable, the user enters the actual value of the current, as measured by an external DMM.
CALIBRATION TEC Calibration Procedures CHAPTER 3 After the last “TEC:ITE” value is entered, the “*OPC?” query may be used to determine when the calibration sequence is done. However, the *OPC”, or “*WAI” command, or “*OPC?” query should not be issued until after the last “TEC:ITE” value is entered or the system will “hang”. This happens because the LDC-3900 will wait indefinitely for an input, yet not allow any input until the calibration is finished.
