No. 21 Bernoulli’s Theorem
Determines the fi xed value (
C
) of an inviscid fl uid (steady fl ow, incompressible fl uid) when
the fl ow velocity (
v
), location (height) (
z
), specifi c weight (
ρ
), and pressure (
P
) are known.

No. 22 Calculations Using a Stadia (Height)
Determines the difference in elevation (
h
) from the transit to the leveling rod after a transit
is used to read the length on the leveling rod (
) between the upper and lower stadia lines,
and the angle of elevation (
Ƨ
).

Program Mode (PRGM)
You can use the PRGM Mode (
,
g
) to create and store programs for calculations you
need to perform on a regular basis. You can include any calculation that can be performed
in the COMP, CMPLX, BASE, SD, or REG Mode in a program.

Program Mode Overview
A
Specifying a Program Run Mode
Though you create and run programs in the PRGM Mode, each program has a “run mode”
that it runs in. You can specify COMP, CMPLX, BASE, SD, or REG as a program’s run
mode. This means you need to think about what you want your program to do and select the
appropriate run mode.

Program Memory
Program memory has a total capacity of 680 bytes, which can be shared by up to four
programs. Further program storage is not possible after program memory becomes full.
