Voltage Calibration Diagram
1. Connect a precision Voltage Source with an output range of 0.000 to 105.000
mV and an accuracy of 0.03% or better to the SIG+ (#3) and SIG- (#5)
terminals. Placement of jumper does not affect voltage calibration.
2. Enter the Program Menu and step through the Program Menu list by pressing
the “SEL” button until CAL is displayed.
3. Press the “blank” button to change no to YES . Press “SEL”.
4. The display shows 00000. Use the “blank” button to increment the access
code to 00006. Press and hold “SEL”.
5. After entering the correct access code, the unit will display IN1 . Follow the
table below for calibration sequence.The unit displays CALC for about 3
seconds after pressing the “SEL” button before proceeding to the next input
point.

10. With the display showing r 0 , set the resistance to 0 ohms, then press the
“SEL” button. The unit displays CALC for a few seconds and then the display
will change to r 400 .
11. With the display showing r 400 , set the resistance to 400 ohms, then press
the “SEL” button. The unit displays CALC for a few seconds and then the
display will change to r 10 .
12. Change the input selector jumper to position ‘A’.
13. With the display showing r 10 , set the resistance to 10 ohms, then press the
“SEL” button. The unit displays CALC for a few seconds and then the display
will change to r 0 .
14. With the display showing r 0 , set the resistance to 0 ohms, then press the
“SEL” button. The unit displays CALC for a few seconds and then the display

15. With the display showing r 20 , set the resistance to 20 ohms, then press the
“SEL” button. The unit displays CALC for a few seconds and then the unit
will return to the CAL program item.
Before exiting the programming menu, verify that the tyPE is set to the desired
type and the input selector jumper is in the appropriate position. Exit
programming and check the calibration. Repeat if necessary
Entering code 85 will place the CUB4RT in a resistance display mode. This
mode is for diagnostic purposes only. When power is removed from the

7. Place the input selector jumper in position ‘B’.
8. Connect a precision resistance decade box with an accuracy of ± 0.01 ohms
to the unit as a three wire RTD. See Resistance Calibration Diagram.
9. With the display showing r 200 , set the resistance to 200 ohms, then press
the “SEL” button. The unit displays CALC for a few seconds and then the
display will change to r 0 .
CALIBRATING THE CUB4TC
The CUB4TC uses stored voltage calibration and cold junction temperature
values to provide accurate temperature and voltage measurements. Over time,
the electrical characteristics of the components inside the CUB4TC will slowly
change with the result that the stored calibration values no longer accurately
define the input circuit. For most applications, recalibration every 1 to 2 years
should be sufficient.
Calibration of the CUB4TC involves a voltage calibration and a cold junction
calibration. It is recommended that both calibrations be performed. The voltage
calibration MUST precede the cold junction calibration. Allow 30 minute warm-
up before performing any calibration related procedure. The following
procedures should be performed at an ambient temperature of 15 to 35 °C (59 to
95 °F).
Calibration should only be performed by individuals experienced in
calibrating electronic equipment.
CAUTION: The accuracy of the calibration equipment will directly affect the
accuracy of the CUB4TC.
Voltage Calibration Check
1. Enter the programming menu and set tYPE to LIN and OFSEt to 0 . Exit
programming.
2. Use a precision DC voltage supply with an accuracy of 0.03% or better.
Connect the negative lead of the power supply to TC- (#5) and the positive
lead of the power supply to TC+ (#3).

CUB4RT, the display will return to its previously programmed state. If the
RTD type is set for Cu427 and the jumper is set to position A, the display will
read 00.000 to 20.000 ohms. All other RTD types with the jumper in position
B, will cause the display to read 000.00 to 400.00 ohms
3. Compare the CUB4TC read-out to the precision DC supply at various points
over the range (–10.00 mVDC to 60.00 mVDC). The tolerance is ± 2 LSD
(±0.02 mV), at all points within this range.
4. Calibrate the CUB4TC if the readings are out of tolerance.
Cold Junction Calibration Check
1. Enter Programming Menu, and verify the following:
tyPE = probe being connected to the unit.
CJC = YES
dISP = 0.0 ° C
OFSEt = 0
Make any necessary changes to programming.
2. Connect a thermocouple probe of known accuracy and type (J, K, E, T, or N)
to the CUB4TC. The probe should match the one selected in programming.
3. Connect a reference temperature probe to measuring end of thermocouple to
monitor temperature. Allow sufficient time for temperatures to equalize (at
least 15 minutes).
4. Compare unit display with reference temperature indicator. The unit display
should equal the reference probe temperature. Tolerance is ±1.0 °C.
5. Calibrate the cold junction temperature if out of tolerance.
