13.1 Replacing the IR Source
13.1.1 IR Source Status Indicator
The Direct Detect® spectrometer is equipped with a highly-efficient, low-power,
air-cooled infrared source with an average life span of 44,000 hours. As the end
of this life span is approached, the hardware diagnostics icon turns yellow. When
you click on the hardware diagnostics icon (Figure 30), the hardware diagnostics
dialog appears and displays the message
End of lifetime is nearly reached
(Figure 31). Samples can still be measured, but performance and reliability may
be compromised and the IR source (cat. no. DDSP00010-LA) should be replaced as
soon as possible.
If the source is defective, the hardware diagnostics icon turns red. When you click
on this icon, the hardware diagnostics dialog appears and displays the message
No
source is connected . Samples can no longer be measured, and the IR source must
be replaced.
13.1.2 Replacing the IR Source
WARNING
: During spectrometer operation the light source becomes very
hot. To avoid burns, wait until the light source has cooled down
before replacing it.
1. Unplug the instrument power plug.
2. On the back of the instrument, loosen the 4 cover plate Torx® screws with the
Torx® TX20 screw driver supplied (Figure 32).
