Parameter values and units are
after “=”.
The regulations are as follows:
N1: nominal value N2: Q/D limit
value
N3: first-class high limit N4:
first-class low limit
N5: second-class high limit N6:
second-class low limit
N7: third-class high limit N8:
third-class low limit
Data format is as follows after
being received and adjusted:
1. N1: X1: ASCII code (0
∼ 9);
X
2
∼ X
6
: ASCII code (0~9 and
point);
X
7
: ASCII code (0 ∼ 2) (unit code)

Example and notes: (symbols used to
express in the examples, and ASCII
code should be used in real-world
program)
1. N1=122 will be automatically
adjusted to N1=12.0002 (7 characters)
after being received by the instrument,
and the last bit is unit code. When
resistance is measured, the nominal
value is 12 M
Ω . That is, N1 starts with
number (the first one from 0~9), the
rest being numbers (0~9) and point,
and ends with unit code. The number of
total characters should be less than 7
after automatic adjustment.
2.
N2=12 will be automatically
adjusted to N2=12.000 (6 characters)
after being received by the instrument,
that is, N2 (Q/D limit value) starts with
number (the first one from 0~9), and
the rest are number 0~9 and point. The
number of total characters should be
less than 6 after automatic adjustment.
3.
N3=1% will be automatically
adjusted to N3=+1.000% (7
characters) after being received by the
instrument, that is, N3~N8 (limit
value) starts with symbols or numbers.
If starting with symbol, the second
character should be number, the rest
being number 0~9 and point, and ends
with %. The total characters should be
less than 7 after automatic adjustment.
