SECTION 6 GLOSSARY

COMMON MODE REJECTION (CMR) - a measure of
the affect of a voltage on the indicated display. It is the
ratio of the common mode voltage to the measured
voltage due to a common mode voltage.
COMMON MODE VOLTAGE (CMV) - the average of
the voltage applied to both wires of a two wire or
differential input.
NORMAL MODE REJECTION (NMR) - a measure of
the rejection of unwanted signal due to a voltage
applied between the wires of a two wire or differential
input (shown as normal mode voltage). NMR is the
ratio of the normal mode voltage to the measured
voltage due to the normal mode voltage.
TEMPCO - abbreviation for temperature coefficient. It
is the effect of changes in ambient temperature on a
particular parameter, such as zero or span settings.
