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.
