4.a INTRODUCTION: CALIBRATION TECHNIQUES
The calibration methods that apply to each 3500 Series conditioner model are
summarized in the following table.
For each instrument, the applicable calibration procedures can be performed
either via the front-panel SETUP buttons or via mnemonic commands received
through the RS-232/485 Interface Port. For the mnemonic commands relating to
each calibration technique, see Section 4.d.
4.a.1 ABSOLUTE CALIBRATION
THE MODEL 3510 THERMOCOUPLE CONDITIONER IS THE ONLY ONE WHICH
EMPLOYS STRICTLY "ABSOLUTE" CALIBRATION. With this kind of calibration, the
zero and scaling characteristics of all allowable thermocouples are fixed and
known. Since calibration values for the TC input are prestored in the 3510’s
processor memory, there is no need for any further calibration procedures, as
