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.
