Comments • For the p3 measurement range, see the range
parameter table on Pages 5-7 and 5-8.
• Set the span in p4 and p5 within the setting range
shown on pages 5-7 and 5-8.
• For p4 and p5 setting value, enter them within 6
digits excluding the decimal point. The decimal
point is fixed. Refer to setting range on pages 5-7
and 5-8.
• The measurement range cannot be changed while
executing a report or computation, or when a file
is written.
Setting DELTA(difference between channels)/
RRJC(remote RJC)
Setting SRp1, p2, p3
p1 Channel number (001 to 560)
p2 DELTA/RRJC
p3 Reference channel (01 to 60)
p4 Span left value
p5 Span right value
Example Set channel 10 of subunit 2 to DELTA that is
difference value from channel 01 of the same
unit,and set span left value to -100.0, span right value
to 100.0.
SR210, DELTA, 01, -1000, 1000
Comments • As the reference channel, set a channel of the
same unit as the channel to be set to DELTA or
RRJC. In addition, the reference channel number
must be smaller than the source channel number.
• For RRJC, input for the reference channel must be
of a thermocouple type.
• If the input mode (type of input, scaling...) or the
measurement range of the reference channel is
changed, DELTA or RRJC setting is cleared. The
input mode changes to the mode before the
reference channel was changed.
• If any change has been made to the number, input
mode (type of input or scaling), or measuring
range of a given reference channel, the alarm
setting of the channel for which the item
“DELTA/RRJC” is being set changes to “OFF.”
• If any change has been made to the number or
input mode (type of input or scaling) of a given
reference channel, to the measuring range, or to
the span of the set channel, the partial-expansion
setting of the channel for which the item
“DELTA/RRJC” is being set changes to “OFF.”
• Set the span in p4 and p5 within the setting range
for the reference channel shown on pages 5-7 and
5-8.
• For p4 and p5 setting value, enter them within 6
digits excluding the decimal point. The decimal
point is fixed. Refer to setting range on pages 5-7
and 5-8.
• RRJC setup is valid only for recorders with the
optional computing function.
• The measurement range cannot be changed while
executing a report or computation, or when a file
is written.

1Ph2W:
Single-phase two-wire system

(only on a three-wire system)
3Ph3W-2I: Three-phase three-wire system
(only on a two-voltage two-
current three-wire system)
3Ph3W-3I: Three-phase three-wire system
(only on a three-voltage three-
current three-wire system)
3Ph4W: Three-phase four-wire system
(only on a three-wire system)
p4 Input range

25 V - 5 A
250 V - 0.5 A
250 V - 5 A
p5 Measurement item
p6 Left value of span
p7 Right value of span
Example Set subunit 1 and channel 01 to single-phase two-
wire system, input range to 25 V - 0.5 A,
measurement item to P1, left value of span to 0, and
right value of span to 100.

Comments • Settings of p3 and p4 are common within one
power monitor module. If the setting is changed,
the settings on other channels also change.
• For the measurement item p5, refer to the list of
measurement items on page 5-9 and 5-10.
• If the measurement item p5 is set on channels 1, 3
and 5, channels 2, 4 and 6 are set automatically
and cannot be changed. If channels 1, 3 and 5 are
set to SKIP, then channels 2, 4 and 6 can be set.
• There is a limit on what can be set on the
measurement item p5 depending on the wiring
method and the settings on other channels. If a
value outside the limit is set, settings on other
channels may change automatically. Set the
settings on each channel within the group
indicated on page 5-10.
