• Set the span values, p6 and p7, within the
measurement range indicated on page 5-8.
• Input values within 6 digits disregarding the
decimal point for p6 and p7. The decimal point
position is fixed to the decimal point position of
the setting range of page 5-8.
• The measurement range cannot be changed while
executing a report.
• The measurement range cannot be changed while
executing a report or computation, or when a file
is written.

Set the measurement range of subunit 1 and channel
01 to 20k, left value of span to 0, and right value of
span to 100.

Comments
• Even when the settings of p3 are the same
parameters, the measurement range of the strain
varies depending on the gauge method. For
details, refer to page 5-9.
• Set spans, p4 and p5, within the measurement
range indicated in page 5-9.
• Input values within 6 digits disregarding the
decimal point for p4 and p5.
• The measurement range cannot be changed while
executing a report or compuration, or when a file
is written.

Example
Set subunit 1 and channel 01 to momentary pulse
count mode, left value of span to 0, and right value
of span to 1000.
SR101, PULSE, RATE, 0, 1000, 0, 1000, 0
Comments
• When omitting p6, p7, or p8, omit all three.
• When summing the count number or the ON time,
set the computational expression with the SO
command, then execute computation start with the
EX command. When the pulse input module is
installed, the use of computation channels become
available without the math option. However, the
only computational expression available in this
case is TLOG.PSUM(XXX) for summing the
count number or the ON time.
• The measurement range cannot be changed while
executing a report or computation, or when a file
is written.

Comments
• For the p4 measurement range, see the range
parameter table on Pages 5-7 and 5-8.
• For the p5 and p6 setting spans, set them in the
ranges shown in the setting range on Pages 5-7
and 5-8.
• For p5 and p6 setting values, enter them within 6
digits excluding the decimal point.
• Select either to set all three parameters, p7, p8 and
p9, or to omit them all.
• The measurement range cannot be changed while
executing a report or computation, or when a file
is written.

Comments
• Settings of p4 and p5 are common within one
power monitor module. If the setting is changed,
the settings on other channels also change.
