Parameters Setup - Newport LDC-3706 Series User Manual

Parameters Setup

SET Button – Allows the user to adjust settings under TEC, LASER, RECALL and STORE. The SET
button will allow the user to open a sub menu or allow the user to adjust the currently selected
parameter. When a parameter is being adjusted, the units will flash at a constant frequency. To
return to the main menu, the sub menu will contain one option that reads "Return <SET>."
TEC Button Uses a menu system for temperature controller setup functions including Limits,
–
Sensor, Sensor Calibration Constants, External Fan Control, Cable Resistance and Analog Input.
The SET button selects the currently displayed menu item or allows the user to adjust the currently
displayed parameter. The ADJUST knob can be used to cycle through or modify the following
parameters:
Limits: The Limits menu allows the user to select and modify the temperature, current,
and sensor upper and lower limits:



Depending on the sensor selected, the user can configure high and low limits for resistance,
current or voltage.
Sensor The Sensor parameter allows the user to select the type of sensor for the
:
application: Thermistor, RTD, IC-V, or IC-I. For more information on temperature
sensors see the Sensor Options section later in this chapter. The sensor type selections
are:




Sensor Calibration Constants: The calibration constants menu allows the user to enter
sensor constants for thermistor, current and voltage IC, and RTD. For more information see
the Sensor Options later in this chapter.
External Fan Control: Allows the user to enable or disable the external fan. The user can
also set the voltage applied to the external fan.
Analog Control Input: Enables and disables the analog input feature, for optimal stability if a
signal is not being applied to it, the analog control input should be disabled.
Calibration: This menu allows calibration of sensor readings (10 µA thermistor, 100 µA
thermistor, 1 mA RTD, 2.5 mA RTD, ICI, and ICV), TEC current output and readings, and
TEC voltage readings. See Chapter 5 for more details.
