Description
The Greenlee TPA-10 Thermocouple Module is an adapter
intended to connect a K-type temperature probe (purchased
separately) to a typical multimeter (also purchased separately)
that has voltage and common (negative) terminals with 3/4"
centerline spacing and is capable of reading millivolts.
The TPA-10 takes temperature probe input and produces a
voltage output. The ratio is 1 mV DC of output to 1°of input.
Safety
Safety is essential in the use and maintenance of Greenlee
tools and equipment. This instruction manual and any
markings on the tool provide information for avoiding hazards
and unsafe practices related to the use of this tool. Observe all
of the safety information provided.
Purpose
This instruction manual is intended to familiarize all personnel
with the safe operation and maintenance procedures for the
Greenlee TPA-10 Thermocouple Adapter.
Keep this manual available to all personnel.
Replacement manuals are available upon request at no charge.

Important Safety Information
Read and understand this material
before operating or servicing
this equipment. Failure to under-
stand how to safely operate this tool
can result in an accident causing
serious injury or death.
This symbol is used to call your attention to hazards or
unsafe practices which could result in an injury or property
damage. The signal word, defined below, indicates the
severity of the hazard. The message after the signal word
provides information for preventing or avoiding the hazard.
SAFETY ALERT SYMBOL
Immediate hazards which, if not avoided, WILL result in
severe injury or death.
Hazards which, if not avoided, COULD result in severe
injury or death.
Hazards or unsafe practices which, if not avoided, MAY
result in injury or property damage.

Electric shock hazard:
Contact with live circuits can result
in severe injury or death.
Important Safety Information
Electric shock hazard:
• Do not use the unit if it is wet or damaged.
• Use test leads or accessories that are appropriate for the
application. See the category and voltage rating of the
test lead or accessory.
• Inspect the test leads or accessory before use. The
item(s) must be clean and dry, and the insulation must
be in good condition.
Failure to observe these warnings can result in severe
injury or death.
Do not operate with the case open.
Failure to observe this warning can result in severe injury
or death.
Electric shock hazard:
• Do not apply more than the rated voltage between any
two input terminals, or between any input terminal and
earth ground.
• Do not contact the test lead tips or any uninsulated
portion of the accessory.
Failure to observe these warnings can result in severe
injury or death.

• Do not attempt to repair this unit. It contains no user-
serviceable parts.
• Do not expose unit to extremes in temperature or high
humidity. See Specifications.
Failure to observe these precautions can result in injury
and can damage the instrument.
Important Safety Information
Do not change the measurement function while the test
leads are connected to a component or circuit.
Failure to observe this precaution can result in injury and
can damage the instrument.
Using this unit near equipment that generates electromagnetic
interference can result in unstable or inaccurate readings.
Set the selector and connect the test leads so that they
correspond to the intended measurement. Incorrect
settings or connections can result in a blown fuse.
Unless measuring voltage, current or frequency, shut off
and lock out power. Make sure that all capacitors are
discharged. Voltage must not be present.

Operation
Battery Check
1. See the instruction manual supplied with the multimeter
(purchased separately).
2. Be sure the TPA-10 is turned OFF.
3. Set the multimeter to DC volts.
4. Connect the TPA-10 module to the voltage input terminals
of the multimeter (observe polarity).
5. Read the display on the multimeter. Replace or recharge
the battery if the reading is less than 7.1 volts.
Temperature Measurement
1. See the instruction manual supplied with the multimeter
(purchased separately).
2. Connect the TPA-10 to the voltage input terminals of the
multimeter (observe polarity).
3. Connect the temperature probe (purchased separately) to
the thermocouple module.
4. Set the meter to read DC volts.
Note: Every degree (Celsius or Fahrenheit) of input will
produce 1 mV of output.
5. Set the thermocouple module to °For °C.
Note: The ON indicator will begin to flash
6. Test the unit in the environment (air, gas, surface, etc.) of
a known temperature.
•If the unit does not function as expected in the
environment of known temperature, replace the battery.
•If the unit produces a very high reading, use an
ohmmeter or continuity tester to see if the thermo-
couple is open.
•If the unit still does not function as expected, send the
unit to Greenlee for repair.
Electric shock hazard:
Contact with live circuits can result
in severe injury or death.

Operation (cont’d)
7. Take the reading from the environment to be tested. If the
resolution is not satisfactory, remove the sensor from the
environment and change the multimeter to the next lower
range.
