Error Indicators

The LDC-3706 instrument indicates operational errors on the measurement display with an error
code and brief description of the error that has occurred. A complete list of error codes can be found
in Chapter 5.

General Operating Procedures

The discussion below presents guidelines for operation as well as some common operating
procedures. Remote operations are discussed in the next chapter.
The output terminals of the LDC-3706 instrument should never be shorted together
or loaded with less than 0.1 Ω. Doing so may result in damage to the instrument.
Temperature control must be enabled prior to the laser output to protect against
thermal runaway of the laser device. In addition, a potential 0.1A operational
transient is present in the LDC-37620 10A/20A High Power Laser Diode Controller if
the laser output is enabled and then the temperature control output is enabled.

Warm-Up and Environmental Considerations

To achieve the rated accuracy, allow the LDC-3706 instrument to warm-up for at least one hour
before use. Always operate the controller within the environmental limits specified in the
Specifications section of Chapter 1. The best accuracy is achieved near the calibration temperature
of 23°C.
