High Temperature K-type,
Clip-on Thermocouple
Model: ATAF1
Max: 900ºF
OPERATOR’S MANUAL
Description
The ATAF1, K-Type, high temperature thermo-
couple. The ATAF1 can be used with any ther-
mometer which accepts a K-type thermocouple.
Unlike a conventional Teflon or Nylon insulation
the ATAF1 fiberglass insulation can withstand tem-
peratures up to 900ºF continous use and 1000°F
one time exposure. This high temperature themo-
couple can be used in residential and commercial
ovens as well as broilers and boilers or any other
application up to 900ºF. The ATAF1 also comes
with a wrap tab making it easy to wind and store the
thermocouple.
Operation
To use the ATAF1 plug it into any thermometer
accepting a K-type thermocouple and adjust the
device to the appropriate settings.
Calibration
Due to variances in the thermocouple wire and
other parts of the system, a field calibration should
be conducted before use. Field calibration typically
gives +/- 1ºF overall accuracy. The instructions for
this calibration should be in the operating manual
for the thermometer.
Specifications
Thermocouple Conductors: K-type Nickel
Chromium/Nickel Aluminum, 2300ºF maximum
(max. temp. is limited by insulation, see probe
insulation).
Accuracy: -50ºF to 545ºF +/- 4ºF,
545ºF to 1000°F +/- 0.75%
Range: -50ºF to 900ºF maximum continous oper-
ation. Single exposure use at 1000°F.
Probe insulation: While calibration and atmos-
phere will affect maximum useful temperature in
applications, this insulation is designated to
withstand a maximum continuous use at 900°F
(482°C) and a single exposure use at 1000°F
(537°C). Note: Impregnations retained to 400°F
(204°C).
Plug: K-Type Thermocouple male mini plug.
Broken Wires:
Due to frequent bending, the K-type thermocou-
ple wire may break or come loose, typically near the
plug. To repair, cut and strip the thermocouple wire
near the plug. The red wire is the (-) wire and it
belongs on the wider of the two plugs. Loosen the
screws on plugs and wind the conductors around
the appropriate screws and tighten. Finally, position
the plugs into the tab and screw the tab back togeth-
er.
Warranty
The ATAF1, K-Type, high temperature thermo-
couple is warranted against manufacturer’s defects
for one year. This warranty does not apply to
defects resulting from abuse, neglect, accident,
unauthorized repair, alteration, or unreasonable use
of the instrument. Any implied warranty arising out
of the sale of Fieldpiece's products including but not
limited to implied warranties of merchantibility, and
fitness for purpose, are limited to the above.
Fieldpiece shall not be liable for incidental or con-
sequential damages.
Service
Any defective ATAF1 should be returned to
Fieldpiece for warranty service along with proof of
purchase.

WARNINGS
When testing high temperatures, the thermo-
couple and metal alligator clip may become hot.
Do not handle the thermocouple or the metal
clip when hot.
