CALIBRATION AND TROUBLESHOOTING
Calibration Overview
116 LDC-3700 Series
CHAPTER 5
5 Press and hold in the (PARAMETER) SET switch and turn the ADJUST knob until the
TEC display indicates the same resistance you recorded for the metal film resistor.
6 Release the (PARAMETER) SET switch to store the new value into non−volatile memory.
After the (PARAMETER) SET switch is released, the LDC−3700B Series Laser Diode
Controller will return to its former state (before calibration).
7 Switch the SENSOR SELECT switch (back panel) to the 10 mA position, TEC display
code −−02, and repeat this procedure with the 100 kΩ resistor as the load at the Sensor +
and Sensor − terminals.
AD590 Sensor Calibration
This procedure is for calibrating the AD590 sensor so that the temperature measurement is as
accurate as possible.
1 Set the SENSOR SELECT switch (back panel) to the AD590 position, the TEC display
code is −−04.
2 Connect a precision 16.8 kΩ (metal film) resistor and multimeter in series at the sensor
input of the Temperature Controller 15 pin connector on the rear panel, Sensor + and
Sensor − terminals. Configure the multimeter to measure current in µA.
3 Enter the TEC sensor calibration mode by pushing the (GPIB) LOCAL and (TEC
DISPLAY) R switches at the same time. The TEC display will become blank for 2
seconds, then the sensor code (SENSOR SELECT switch position) value will be
displayed for 2 seconds. After this, the TEC display will indicate sensor reference current
in µA (not enunciated).
4 Press and hold in the (PARAMETER) SET switch and turn the ADJUST knob until the
TEC display indicates the same current as shown on the multimeter.
5 Release the (PARAMETER) SET switch to store the new value into non−volatile memory.
After the SET switch is released, the LDC−3700B Series Laser Diode Controller will return
to its former state (before calibration).
