Measuring converter
Adapter to connect a meter to the
⇒
D. U. T.
Measuring cycle Cycle set up from the user. After this time the meter
calculates new values. The exact time depends on the
synchronisation frequency.
Measuring settings All parameters of the meter which influence the
measurement.
Memory card Random access memory card to store data.
Menu The whole measurement settings are divided in menus to get
a better survey.
Miscellaneous In this menu you can set up several parameters which have
no direct influence on the power measurement, like contrast
time and date.
Multimeter Meter which can measure several values like voltage, current
and resistance.
N
Nibble Half of a byte; upper or lower 4bit.
Noise Usually random signals with a high bandwidth which are
superposed to the useful signal.
Nondecimal numeric program data Data which can be represented as string instead of a number;
e. g. ‘Cont on’ instead of ‘Cont 1’.
Non-linear component losses Losses caused by non linear loads like inductivities or
capacitors or amplifier circuits.
Null modem Type of serial connection between a PC and another device;
the connection cable has two crossed conductor pairs.
O
Open collector outputs Passive outputs where the user has access to the collector of
the output transistor. You have to connect an external
voltage supply to this collector to use the output.
Operator Instruction which is taken into the calculation: +, -, *, /.
Option Key A string which can be used to implement software options
