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
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.
DANGER:
1. Voltages present at the
thermocouple may also be present
at the battery terminals. Always
disconnect the thermocouple
when changing batteries.

digits and indicators, should remain
on for approximately one second.
The thermometer will then display
the thermocouple type and resume
to the measurement mode.
8. CONNECTING A
THERMOCOUPLE
Use the correct thermocouple type for
your instrument. Using an incorrect
thermocouple type will result in
erroneous readings. Thermocouples
are color
coded by type using the North
American ANSI Color Code as follows:
TYPE COLOR
J
Black
K Yello
w
T Blue
Thermocouple connectors have one
wide blade and one narrow blade.
Do not force connector in backwards.
Connect thermocouple to receptacle
at top of instrument as shown in the
following illustration:
