Introduction
The control panel of the TLD001 Laser Diode Controller T-Cube contains a 5 digit 7
Segment display, adjustment potentiometer, Mode, Display and Laser ON buttons,
and a keyswitch.
The following brief overview explains how the front panel controls can be used to
perform a typical series of operations.

Main Display
- 5 dig it LED display. Can be se t to show one of 4 operating
parameters as follows:
•I
LIM
- the maximum drive current limit (see Section 3.3.6. and Section 4.4.)
•I
LD
- the laser diode drive current in mA
Note
. The maximum value available is dependent upon the laser diode drive
current limit - see Section 3.3.6. and Section 4.4.
•P
LD
- the laser diode optical output power in mW
Note
. The maximum value is dependent upon the photodiode current range
(I
PD
), set by the rear panel micro switches (Section 3.3.7.), and the power
display calibration setting see Section 4.4.
•I
PD
- photo diode current in mA.
Note
. The maximum value is dependent upon the photodiode current range
(I
PD
), set by the rear panel micro switches (see Section 3.3.7.).
The corresponding LED is lit when a parameter is selected. In addition, the I
LIM
LED starts flashing if the max drive current limit is reached.
