NX: it is relative setting parameters.
Parameter’s value and unit follows symbol “=”.
Rules:
N1: Nominal value
N2: Q/D limits
N3: High limit of grade 1
N4: Low limit of grade 1
N5: High limit of grade 2
N6: Low limit of grade 2
N7: High limit of grade 3
N8: Low limit of grade 3
N9: High limit of secondary parameter
N0: Low limit of secondary parameter
After receiving data, the instrument will automatically
adjusted data into below format:
1) X1
B
: ASCII code of 0~9.
X2~XB
6B
: ASCII codes of 0~9 and decimal points.
XB
7B
: ASCII code of 0~2. Here XB
7B
is defined as below:
2) N3~N8
XB
1B
: ASCII codes of “+” and “-”.
X
2
: ASCII codes of 0~9.
X
3
~X
6
: ASCII codes of 0~9 and decimal points.
X
7
: ASCII code of % (N2, N9).
3) N0, N9
XB
1B
: ASCII codes of “+” and “-”.
X
2
~X
6
: ASCII codes of 0~9 and decimal points.
X
7
: ASCII code of 0~2.
4) N2
X
1
~X
6
: ASCII codes of 0~9 and decimal points.
Note: N2 is only valid for secondary parameters D/Q. D
with high limit and without low limit. Q with low limit and
without high limit.
Examples and remarks:
(Symbols are used in the following
examples and remarks. Please change
to ASCII code when writing
commands.)
1) N1=122 The instrument adjusts it
as N1=12.0002 (7 bit) after
receiving. The last bit is code for
unit. For resistance measurement,
nominal value here is 12 MΩ. That
is:
N1 starts with numerical values
and ends with code of unit. Its first
bit must be 0~9, while other bits
contain 0~9 or decimal points.
After adjusted by the instrument, it
is less than 7 bit.
2) N2=12 The instrument adjusts it as
N2=12.000 (6 bit). That is:
N2 (high and low values of D/Q)
starts with numerical values and
ends with code of unit. Its first bit
must be 0~9, while other bits
contain 0~9 or decimal points.
After adjusted by the instrument, it
is less than 6 bit.
3) N3=1% The instrument adjusts it
as N3=+1.000% (7 bit) after
receiving. The last bit is code for
unit. That is:
N3~N8 (high and low values) starts
with symbols or numerical values,
and ends with “%”. If it starts with
a symbol, the second bit must be
numerical values. Other bits must
contain 0~9 or decimal points.
After adjusted by the instrument, it
is less than 7 bit.
Query setting values of the instrument. When the instrument
receives this command, it sends corresponding command to
the computer for one time in below format:
{ NX=XB
1B
XB
2B
XB
3B
XB
4B
XB
5B
XB
6B
XB
7B
}
According to command 46, the data is adjusted automatically
by the instrument as X2~XB
6B
:999999
