#D,m,?; - command cannot be executed

9) #D,f,<address>; function enables the user to delete directory and its contents (files and

subdirectories):

Response:

#D,f; - command was executed

#D,f,?; - command cannot be executed

A.7 FUNCTION #5 – STATISTICAL ANALYSIS RESULTS READ-OUT

#5 function enables one to read out the statistical analysis results.

#5 function format is defined as follows:

#5,p;

where:

p - the number of the profile (1, 2 or 3)

The device responds, sending the current classes of the statistics in the following format:

#5,p;<Status Byte> <LSB of the transmission counter> <MSB of the transmission counter>

Status Byte gives the information about the current state of the instrument.

where:

D7 = 0 means "overload does not happen",

= 1 means "overload appeared",

D6 = 1 reserved,

D5 = 0 instantaneous current result (RUN State),

= 1 final result (STOP State),

D0 to D4 reserved bits.

Note: There is not any succeeding transmission in the case when the Status Byte is equal to

zero.

The transmission counter is a two-byte word denoting the number of the remaining bytes to be

transmitted. Its value is calculated from the formulae:

Transmission counter = 6+n * (4 * the number of the classes in the statistics)

where:

n the number of the transmitted statistics. For p = 1, 2 or 3 only one statistic is transmitted (n = 1).

NofClasses is a two-byte word denoting the number of classes in the statistic.

BottomClass is a two-byte word denoting the lower limit of the first class (*10 dB).

ClassWidth is a two-byte word denoting the width of the class (*10 dB).

Counter of the class is a four-byte word containing the number of the measurements belonging to the

current class.

Note: The bytes in the words are sent according to the scheme <LSByte>..<MSByte>.
