Performance specifications
(Note)
Accuracy rating
±0.1% when measuring span is ¹/10 or more
of maximum span
±(0.05 + 0.005 x maximum span/measuring
span)% when measuring span is less than
1_{/10 of maximum span}
Note: Percent value with respect to measuring span (including
linearity, hysteresis and repeatability in standard 23°C status)
Ambient temperature effect:
Zero shift: ± (0.1 + 0.05 × URL/x )%/ 28°C
Overall shift: ± (0.15 + 0.05 × URL/x )%/
28°C
Where; URL: Maximum span
x : Measuring span
3 times as large as above when the 7th
digit (material) is other than V.
Maximum allowable pressure effect:
Zero shift at maximum span
± 0.2% to maximum allowable pressure
Inclination effect:
0.1 kPa/10° or, when 13th digit code (pro-
cessing, fill fluid) is W, D or A, double the
above, at maximum span
Measurement period:
