Commands

• 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.

p9 Decimal point position of scale (0 to 4)

Example Measure using the measurement range of 2k for

subunit 0 and channel 01, and convert 0µε to 0.00

and 1000µε to 100.00.

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.

Mode Operation mode

Setting SNp1, p2<terminator>

p1 Channel number (001 to 560)

Computation channel number (A01 to A60)

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.

XQ Sets the filter.

p1 ON Filter on

OFF Filter off

Example Insert a filter in the input.

XQON

XV Sets the measurement period.

Mode Setup mode

Setting XVp1<terminator>

p1 Measurement interval (0.5, 1, 2, 3, 4, 5, 6,

10, 12, 15, 20, 30, or 60)

Example Set the measurement period to 10 seconds.

XV10

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.

Integration time: Equivalent to 50/60 Hz
