Data Storage with PROFITEST PV
SUN MEMO
The
PROFITEST PV
SUN MEMO
test instrument is equipped with an
internal memory for the storage of 10,240 data records. The
stored data can be read out via a USB port for subsequent evalu-
ation from a PC. Furthermore, the included PC software allows for
the creation of individual test structures.

Function Description
Switch between standard measurement display
and storage display
Switch to previous object or string
Switch to next object or string. If the last object or
string is reached, a new object or a new string
can be created by pushing this key (> 2 s).
Switch between objects and strings. Symbol
►
indicates whether objects or strings are active
(e. g.:
►
OBJ:Object1).

Standard measurement
display with activated
storage function.
If a measurement is per-
formed, the measured
values are stored under
the object and string
selected before.
Note
Stored values are overwritten in the activated object/
string.

OBJ:Object1 /
STR:String1 are active.
Presently, one object (1/1)
and one string (1/1) have
been created.

Note
If objects and strings are extended in the test instrument,
it is not possible to assign alphanumeric characters.
There is only an incrementation instead (gradual increase
by one character each).
