• For the measurement item p6, refer to the list of
measurement items on page 5-9 and 5-10.
• There are items that can not be set on the
measurement item, p6, depending on the wiring
method or the settings on other channels. Set
within the group indicated on page 5-10.
• Set the span values, p7 and p8, within the
measurement range indicated on page 5-8.
• Input values within 6 digits disregarding the
decimal point for p7 and p8. The decimal point
position is fixed to the decimal point position of
the setting range of page 5-8.
• For p9, p10, and p11, either set all the three
parameters or omit all three.
• The measurement range cannot be changed while
executing a report or computation, or when a file
is written.

Comments • Even when the settings of p4 are same parameters,
the measurement range of the strain varies
depending on the gauge method. For details, refer
to page 5-8.
• Set spans p5 and p6 within the measurement range
indicated in page 5-8.
• Input values up to 6 digits disregarding the
decimal point for p5 and p6. The decimal point
position is fixed to the decimal point position of
the setting range of page 5-8.
• For p7, p9, and p10, either set all the three
parameters or omit all three.
• The measurement range cannot be changed while
executing a report or computation, or when a file
is written.
SN Sets the scaling unit.

p2 Unit character string (up to 6 characters)
Example Set the scaling unit for channel 01 of subunit 0 to
ABCDEF.
SN001, ABCDEF
Comments • For a character string that can be used as units, see
the characters in Section 5.6, “ASCII Code
Table.” However, note that a semi-colon “;”
cannot be used.
• The optional computation channel number for a
stand-alone model is A01 to A30.

Comments • 0.5s and 1s are only for DR232 and DR242.
• The shortest measurement period that can be set
differs depending on the A/D integration time and
the filter on/off setting as follows.
