2. SAFETY PRECAUTIONS

WARNING:

1. This instrument is designed to
accept low level signals supplied by
standard Thermistors. 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 Thermistor

may also be present at the battery
terminals. Always disconnect the
Thermistor when changing batteries.
