Equipment needed
Table 6-4 lists the equipment you will need to calibrate the specific types
of inputs that are listed in table 6-1. You will need a screwdriver to
connect these devices to your controller.
Table 6-4 Equipment Needed
Type of Input Equipment Needed
Thermocouple Inputs
(Ice Bath)
• A calibrating device with ±0.01% 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.
Thermocouple Inputs
(Precision Resistor)
• A calibrating device with ±0.01% 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 #5 terminals 1(R) and 3(–).
Thermocouple Inputs
(Ambient Temperature)
• 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.
RTD (Resistance
Thermometer Device)
• A decade box, with ±0.01% 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.
Milliampere, Millivolt, Volts,
and Radiamatic
• A calibrating device with ±0.01% 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 UDC6300 input.
