TAC80B-J, K, T Thermocouple to Analog
Converter can turn any chart recorder, analog or digital
voltmeter into an accurate, wide range temperature
measuring instrument. It is powered by either an internal
9 volt battery or an optional power adapter (TAC80B-AC).
The TAC80B is a universal thermocouple amplifier and
linearizer which provides a precision 1mV/°C or °F signal
for type J, K or T thermocouples. Cold junction compen­sation is built in. Each unit is supplied with mating con­nector, standard-to-miniature connector adaptor, and 9V
battery.

Remove the Packing List and verify that you have
received all items. If you have any questions about the
shipment, call the Customer Service Department. When
you receive the shipment, inspect the container and
equipment for any signs of damage. Note any evidence of
rough handling in transit. Immediately report any damage
to the shipping agent.
NOTE: The carrier will not honor any claims unless all
shipping material is saved for their examination. After
examining and removing contents, save packing material
in the event reshipment is necessary.

1. Connect the TAC80B to the strip chart recorder or

meter. The HI plug connects to the HI (+) receptacle
and the LO plug to the LO (-) receptacle.

2. Plug the thermocouple into the SMP socket on the

TAC80B.

CAUTION: When the range switch is in the TEST position
(center), full battery voltage (9V) is applied to the
output. The power switch must be in the OFF position
before switching from °F to °C or vice-versa (see
Figure 1-1).

Multimeter Use

1. For temperatures less than 200°C or 200°F, set the
multimeter range to 200 mV.

2. For temperatures greater than 200°C or 200°F, set the
multimeter range to 2 V.

Temperature is read directly on the multimeter in °C or °F;
the TAC80B converts the mV signal into a temperature
measurement displayed in °C.

Strip Chart Recorder Use

To use the TAC80B with a strip chart recorder, set the
recorder span to the mV range that corresponds to the mV
output at that temperature to be measured. For example,
to read between 50°C and 150°C, set the range to 100
mV in the CALIBRATE mode and suppress the zero by
50 mV.

NOTE: Output is 1 mV per °C or 1 mV per °F.
