TECHNICAL SPECIFICATIONS
5.1
General
The tolerances assigned to the values, or declared limits,
constitute only the values guaranteed by the manufacturer.
Values without a tolerance are for information only.
The symbol
is displayed when the input signals exceed
the limit values possible in each measurement range.
The symbol
-
is displayed in °C/°F measurement when
there is no input signal (open circuit).
5.2
Characteristics
Accuracy is to within ± [% of the reading (L) + number of
counts (cts)] in the reference conditions indicated in the
appendix.
