•The AC adapter has circuits with high voltage inside that could present
danger of electrical shock or fire if exposed. If the AC adapter is damaged
in any way or becomes hot, discontinue its use immediately, disconnect it
from any AC supply, and have it replaced. Do not attempt to open, repair,
or continue using a damaged or defective AC adapter.
•The instrument batteries can present danger if not handled properly. To
avoid the risk of exposure to dangerous substances or explosion, immedi-
ately remove the batteries and discontinue use if they leak or become
damaged. Never allow the batteries to be shorted, heated, punctured, or
dropped. If the instrument is physically damaged, immediately remove
the batteries to insure that they do not become shorted. While removed
from the instrument, store the batteries in a location so that they do not
come into contact with metal or fluids that might short circuit the batteries
and where they are safe from excessive temperatures. Used batteries must
be disposed of properly. Check your local regulations for additional infor-
mation. Never dispose of batteries in fire which may result in explosion
with the possibility of personal injury or property damage.
•DO NOTuse this instrument in combination with any probe (RTD or
thermistor) to measure the temperature or resistance of any device that is
electrically energized. Severe electric shock, personal injury, or death may
occur.
1.2.2 CAUTIONS
Toavoid possible damage to the instrument, follow these guidelines.
•If the instrument is dropped, struck, or handled in a way that causes inter-
nal or external physical damage, immediately unplug the AC adapter, re-
move the batteries, discontinue use, and contact the factory for repair. Do
not attempt to disassemble or repair the instrument, batteries, or AC
adapter. Refer repairs or replacement components to the manufacturer.
•The instrument and thermometer probes are sensitive and can be easily
damaged. Always handle these devices with care.DO NOT allow them to
be dropped, struck, stressed, or overheated.
•DO NOTleave the AC adapter plugged in for more than 24 consecutive
hours or the battery life could be degraded.
•Probes are fragile devices which can be damaged by mechanical shock,
overheating, and absorption of moisture or fluids in the wires or hub.
Damage may not be visibly apparent but nevertheless can cause drift, in-
stability, and loss of accuracy. Observe the following precautions:
•DO NOTallow probes to be dropped, struck, bent, or stressed.
•DO NOToverheat probes beyond their recommended temperature range.
•DO NOTallow any part of the probe other than the sheath to be im-
mersed in fluid.
•DO NOTallow the probe hub or wires to be exposed to excessive temper-
atures.
