BASIC OPERATION
INTRODUCTION
This section expands on the description of the EX10xxA’s / RX10xx’s features and explains how
to best use them.
ENGINEERING UNIT (EU) CONVERSION
Each EX10xxA/RX10xx input channel can be individually configured for one of eleven different
EU conversions. The selections and their definitions are:

TABLE 3-1: ENGINEERING UNIT CONVERSION SETTINGS
Voltage The instrument will return the raw voltage measured at its input
with units of volts (V). It is unaffected by the measured or input
CJC temperature for that channel.
Type J, K, T, E, S, R, B, N The instrument will return the compensated thermocouple
temperature measured at its input with units of temperature (ºC or
ºF). The thermocouple calculations are performed using the full-
order polynomial equations and coefficients from the NIST ITS-
90 Thermocouple Database.
User-defined 0, User-defined 1 The instrument will return the compensated thermocouple
temperature measured at its input with units of temperature (ºC or
ºF). The thermocouple calculations are performed using user-
defined coefficients for the polynomial equations. More
information on this is given under User-defined Conversions.
The default selection is voltage.
