Appendix A Specifications
1. Resolution in % is the value
of RES command or
parameter (reading
resolution as percentage of
measurement range).
2. Additional error beyond
±1°C, but within ±5°C of
last ACAL. (% of Range)/

4. Reading time is the sum of
the Sec / Reading shown for
your configuration. The
tables will yield the slowest
reading rate for your
configuration. Actual
reading rates may be faster.
For DELAY– 1; ARANGE
