If necessary, clean the sensor window and reflective cup with a cotton
swab dipped in alcohol. Periodic cleaning is a good practice.
4.3 Storage
When not in use, store the DX such as to protect the unit from dirt and
dust. Do not store the unit in areas of extreme heat, cold, or humidity.
If not using the DX for a long period, remove the battery from the unit.
4.4 Calibration
The DX is factory calibrated under high quality standards. Because
there are no mechanical adjustments, the instrument is able to main-
tain its calibration through vibration and normal use. No field calibra-
tion is necessary.
Chapter Five - Troubleshooting
5.1 Diagnostic Codes
The high-performance DX™ continuously monitors its ability to pro-
duce accurate temperature readings. If either the target's tempera-
ture or the unit's ambient temperature exceeds the operational limits,
the display will default to an error message.
The battery voltage is also monitored. A low battery is indicated by a
separate error code. The unit will continue to operate as long as
accuracy can be assured. If the battery drops below 5.7 volts, the
battery is considered "dead" and the display defaults to [----].
If the [E-##] or [Err] error messages are displayed, the unit will not
function and must be returned to the factory for repair. (See section
on Warranty for return instruction).
The following charts summarize the fault condition, and the associat-
ed indication.
