K-type, Clip-on
Thermocouple
Model: ATA1
Max: 400ºF
OPERATOR’S MANUAL
Description
The ATA1, K-Type, thermocouple can be used
continuously to take temperature readings up to
400ºF and a one time use of 482ºF. The ATA1 can
be used with any thermometer which accepts a K-
type thermocouple.
The alligator clip allows the user to affix the ATA1
to a fixed surface, allowing the user to take hands
free measurements. The ATA1 also comes with a
wrap tab making it easy to wind and store the ther-
mocouple.
Operation
To use the ATA1 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
(insulation limits max. see probe insulation).
Accuracy: -50ºF to 400ºF +/- 4ºF,
Range: -50ºF to 400ºF maximum continuos oper-
ation. Single exposure use at 482°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 400°F
(240°C) and a single exposure use at 482°F
(250°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 ATA1, K-Type, clip-on thermocouple is war-
ranted 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 merchantability, and fitness for
purpose, are limited to the above. Fieldpiece shall
not be liable for incidental or consequential dam-
ages.
Service
Return any defective ATA1 to Fieldpiece for war-
ranty service along with proof of purchase. Contact
Fieldpiece for out of warranty repair charges.
