Specified channel statistical operators
Type
Operator
Example
Description
Maximum value
TLOG.MAX() TLOG.MAX(001) Obtain the maximum value of the measured data of channel
001.
Minimum value
TLOG.MIN()
TLOG.MIN(002) Obtain the minimum value of the measured data of channel
002.
Max-min value

* Statistical computation of the measured data from the start of the statistical computation until it is
stopped. When combining with each of the operators, MAX(), MIN(), P-P(), SUM(), and AVE(), the
value that can be specified inside the () is limited to the input channel number or the computation channel
number (refer to next page) (Example: TLOG.MAX(A01)).
