PREACT The number of units above or below the set point
value of which the relay will trip. Use as an “in flight”
compensation value.
PREVIOUS KEY A key used to step back through menus.
PROMPTS Instructions or options presented in a menu by the

PROTOCOL Network protocols are standards that allow computers
to communicate. A protocol defines how computers
identify one another on a network, the form that the
data should take in transit, and how this information is
processed once it reaches its final destination.
RAM Random-Access-Memory. Read/write memory out of
which the microprocessor can both write and read
data.
RATE OF CHANGE
(ROC) A measure of the rate at which weight is changing.
For example: If 100 pounds were dispensed in 1 min-
ute, the rate of change (ROC) would be 100 lb/min-
ute.
REPEATABILITY The maximum difference between readings for
repeated readings under identical conditions. (Also
called reproducibility)
RESOLUTION Resolution is the value of the finest division of the
scale.
ROM Read-Only-Memory. This permanent, non-volatile
memory gives the processor instructions and cannot
be altered.
RTS Request to send an RS-232C level, signaling a readi-
ness to send.
RXD Received data at a serial port. Accepts RS-232C data
signals.
SCALE CAPACITY The maximum amount of weight the scale is capable
of supporting. (Live load plus dead load).
