(22)Temperature Conversion Function (
Δ
T)
(23)Statistical Calculations
Operation Utilizing the temperature-dependent nature of resistance, the temperature con-
version function converts resistance measurements for display as tempera-
tures.
Formula

Setting ON/ OFF
(Fixed when the comparator function is off;
Δ

Maximum number of
data points 30,000
Calculations Total data count, Number of valid data samples, Mean, Minimum value (index
no.), Maximum value (index no.), Standard deviation of sample,
Population standard deviation
• When the comparator function is ON
Count for each comparator judgment, Process capability indices (disper-
sion, bias)
• When the BIN function is ON
Count for each BIN number, OUT (Hi or Lo) count for all BIN numbers,
invalid BIN count
Clearing calculations Clear all data / clear 1 data point (to revert to data immediately before mea-
surement)
Default setting OFF
