Indicates the overall
alignment and proper gain
adjustment for the system.
Battery life
AC or
>30 min
30–5 min
<5 min
Source 1.9 A
>2.2
or
<1.6
>2.5 or
<1.0
Indicates a problem with
the source control voltage
or that the source has
burnt out. Both voltage and
amperage are displayed;
however, amperage
provides a sufficient
diagnostic.
Laser signal 15,000–3,000
>15,000 or
<3,000
>17,000 or
< 2,000
Can verify gross alignment
errors even if the
reflectance cap is not in
place.
Detector

Indicates a problem with
the cooling circuitry or an
ambient temperature over
the specified range.
CPU
temperature
10–75
>75
