Press ENT to begin the thermocouple calibration
procedure. The display will show TC Type alternating with
the thermocouple type. If the thermocouple type is
correct, go to the next step. Otherwise, press the ENT key
and use the

and

keys to change the type. When the

correct type is displayed, press the ENT key to lock in the
type. Note that if the type is changed, the upper and lower
ranges will be set to the widest possible range. Be sure to
check the upper and lower range after setting the type.

Press the

key to display Units alternating with the

current degree units. If the temperature degree units are
correct, go to the next step. Otherwise, press the ENT key
and use the

and

keys to change the value to either

Deg C or Deg F. When the correct units are displayed,
press the ENT key to lock in the units. Note that if the
units are changed, the upper and lower ranges will be set
to the widest possible range. Be sure to check the upper
and lower range after setting the units.

Press

to advance to the Upr Rng display which

alternates with the upper temperature range. If the upper
range is correct, go to the next step. Otherwise, press the
ENT key and use the

and

keys to change the upper

range. The upper range must be at least 100°C or 250°F.
When the upper range is correctly displayed, press ENT
to lock in the value.

Note: the lower range is fixed at 0°C or 32°F and cannot
be changed.

With the temperature range properly set, press the

or

keys to get to the Hi ADC V display alternating with its

voltage value. Press the ENT key to begin voltage
calibration. Using the thermocouple simulator, simulate
the upper limit temperature and adjust the gain
potentiometer on the module such that the voltage
displayed is between 4.200 volts and 4.700 volts. Press
ENT to lock in the upper limit voltage.

Press the

key twice to get to the Lo ADC V display

alternating with its voltage value. Press the ENT key to
begin voltage calibration. Using the thermocouple
simulator, simulate the lower limit temperature. Do not
adjust the gain potentiometer in this step! Press ENT to
lock in the lower limit voltage.

The thermocouple process module is now calibrated for
the specified range. Press

to return to the Run Mode.
