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.

7. CONNECTING A THERMISTOR
Use the correct 400 series Thermistor for
your instrument. Using an incorrect probe
type will result in erroneous readings.
Insert the bayonet plug into the mating
connector on the top of the instrument.
If no probe is connected the display will
read “open”.
Thermistor
s are sensitive at the tip or
sensing element . W hen taki ng
measurements , allow tim e for the reading
t
o stabilize. Mu ltip lying the tim e constant
of the probe by 5 will give you the
approx imat e time required .
