A measure of the correctness of a measurement. See also the appendix 
Accuracy, Precision, and Resolution
 (p. 522). 
 
Term: A-to-D 
Analog-to-digital conversion. The process that translates analog voltage 
levels to digital values. 
 
Term: amperes (A) 
Base unit for electric current. Used to quantify the capacity of a power source 
or the requirements of a power-consuming device. 
 
Term: analog 
Data presented as continuously variable electrical signals. 
 
Term: argument 
Parameter 
(p. 508): part of a procedure (or command) definition. 
Argument 
(p. 489): part of a procedure call (or command execution). An 
argument is placed in a parameter. For example, in the CRBasic command 
Battery(dest), dest is a parameter that defines what argument is to be put in 
its place in a CRBasic program. If a variable named BattV is to hold the 
result of the battery measurement made by Battery(), BattV is the argument 
placed in dest. In the statement 
Battery(BattV) 
BattV is the argument.
