Table 7-2 lists the equipment you will need to calibrate the specific types
of inputs that are listed in the table. You will need a screwdriver to
connect these devices to your controller.

• A calibrating device with ± 0.02 % accuracy for use

as a signal source such as a millivolt source.

• Thermocouple extension wire that corresponds with

the type of thermocouple that will be used with the
controller input.

• Two insulated copper leads for connecting the

thermocouple extension wire from the ice baths to
the precision calibrator.

• Two containers of crushed ice.

• A calibrating device with ± 0.02 % accuracy for use

as a signal source such as a millivolt source.

• Two insulated copper leads for connecting the

calibrator to the controller.

• A precision 500 ohm resistor ± 0.1 % connected

across input #1 terminals 25 (R) and 27 (–) or input
#2 terminals 22 (R) and 24 (–).

• A decade box, with ± 0.02 % accuracy, capable of

providing stepped resistance values over a
minimum range of 0 to 1400 ohms with a resolution
of 0.1 ohm.

• Three insulated copper leads for connecting the

decade box to the controller.

• A calibrating device with ± 0.02 % accuracy for use

as a signal source.

• Two insulated copper leads for connecting the

calibrator to the controller.

• Place current source at zero before switching ON.

• Do not switch current sources OFF/ON while

connected to the UDC 3300 input.
