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
nonhazardous.
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.

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”.
Thermistors are sensitive at the tip or
sensing element. When taking
measurements, allow time for the
reading to stabilize. Multiplying the time
constant of the probe by 5 will give you
the approximate time required.
