Nickel-cadmium batteries should be recharged as follows:
a. Be sure the radiometer is turned off.
b. Plug the jack of the DM-15C0001 recharger into the receptacle at
the back of the radiometer.
c. Set the recharger at the proper voltage and plug it into an appro-
priate AC power source.
d. Approximately 12 hours are required to fully charge the batteries.
6.7 RECHARGEABLE BATTERY CARE
a. Avoid discharging rechargeable batteries completely or leaving
discharged cells in the radiometer for long periods of time.
b. Ensure that all newly purchased rechargeable cells are charged
for at least 15 minutes before operating the radiometer.
6.8 PREVENTIVE MAINTENANCE
6.8.1 Daily Care
a. Immediately clean all spilled materials from the radiometer and
wipe dry. If necessary, moisten a cloth with soap and water to
clean plastic surfaces and the sensor head. The sensor surface
should be rinsed with ethanol to remove any residual soap and/or
organic contaminants.
b. Whenever possible, avoid exposure or usage in areas that are
subject to temperature and humidity extremes, vibration or
mechanical shock, dust or corrosive fumes, or strong electrical or
electromagnetic interference.
