THERMOCOUPLE
The sensor supplied is a fast response beaded
Type-K thermocouple. Maximum temperature
for this sensor is 482 °F (250 °C), with short
term usage to 572 °F (300 °C). Accessory
thermocouples are available for measuring
temperatures throughout the entire range of
the unit (See “Accessories”). Only Type-K
thermocouples may be used with this unit.
Longer leads and extensions may be used.
The lead effect for 164 feet (50 meters) is
generally less than 0.2 °C with a limit of error
of 2.2 °C. Type-K wire and connectors must
be used.
OPERATION
Insert the thermocouple plug into the socket
at the lower edge of the instrument. The
plug and socket are keyed with a small and
large pin. Make certain the plug is inserted
correctly, do not insert the plug incorrectly and
force it.
Slide the ON/OFF switch to ON to turn the
unit on. If there is no thermocouple (an open
condition) the unit displays a 1 on the left side.
Place the thermocouple in contact with
the material to be measured and read the
temperature on the display.
Slide the ON/OFF switch to OFF to turn the
unit off. To conserve battery life, always turn
the unit off when not in use.

BATTERY REPLACEMENT
Erratic readings, faint readings, no display
or LO BAT appearing on the display are all
indications that the battery should be
replaced. To replace the battery, slide the
battery cover, located on the back of the unit,
in the direction of the arrow (away from the
instrument). Remove the exhausted battery
and replace it with a new 9 volt alkaline
battery. Replace the battery cover.
