2. SAFETY PRECAUTIONS
WARNING:
1. This instrument is designed to
accept low level signals supplied
by standard thermocouples. Under
NO circumstances should the input
voltage exceed the specified 50V
RMS.
2. To prevent ignition of a hazardous
atmosphere, batteries must only be
changed in an area known to be
non-hazardous.
CAUTION:
1. Do not use or store this instrument
in microwave ovens or any
abnormally hot or cold areas.
2. Weak batteries should not be left in
the instrument. Dead batteries can
leak and cause damage to unit.
DANGER:
1. Voltages present at the
thermocouple may also be present
at the battery terminals. Always
disconnect the Thermocouple
when changing batteries.
