When you are in SETUP MODE and press the
button, the unit will display the name of the calibration technique that is currently
in effect. Thus, if your 3500 instrument was last set up for "TWO-POINT" calibra-
tion—either "actual" or "simulated"—the display will read
If you wish to use "TWO-POINT" calibration, press ENTER and follow the instruc-
tions given in Section 4.c.2, below.
If you don't want to use "TWO-POINT" calibration, press CAL again. The unit will
display the next calibration method in the sequence—which, in this case, is "LIN"
(for "LINEARIZATION"):
Note that the Model 3510 Thermocouple Conditioner does not offer this cali-
bration method.
If you wish to use the 15-segment internal linearization, press ENTER and pro-
ceed to Section 4.c.4, below. If not, press CAL again. The unit will display "CALC"
(for "CALCULATED" calibration):
If you wish to use "CALCULATED" calibration, press ENTER and proceed to Sec-
tion 4.c.5, below. Pressing CAL again at this point will return you to the "2 PT" dis-
play. To exit the CAL button sequence and return to the "Setup" display, press
SETUP .
NOTE: The calibration method that is on display when you press the SETUP but-
ton becomes the subsequently active method, and will be the one that therefore
first appears when you next press the
CAL button. You can change the currently
active calibration method from the RS-232/485 Port by means of the CALIBRA-
TION (CAL) command, as explained in Section 4.d.
