Strain
The measurement mode should be 2 k, 20 k, or 200 k. The measuring ranges are as
shown below depending on the measurement modes and gauge methods.
Gauge method 2 k 20 k 200 k
1-gauge method –2000 to 2000 µε –20000 to 20000 µε –200000 to 200000 µε
2-gauge method
–1000 to 1000 µε –10000 to 10000 µε –100000 to 100000 µε
4-gauge method
–500 to 500 µε –5000 to 5000 µε –50000 to 50000 µε
Note
If you have connected any new strain gauge or changed the measuring range initial balancing
is necessary. (Initialization of settings or reconfiguration of the system also changes the
measuring range back to its default).
•
PULSE (not possible for DR130/231/241)
Select the RATE or GATE range.
• DELTA (difference between channels)
Computation can be done only in the same unit. Destination channels should lie
within the first channel No. to the last channel No. range. The number of the reference
channel (REF) should be lower than the number of the destination channels. The
default setting for the reference channel is 01.
The type of input and the measuring range in the destination channel are the same
as for the reference channel. After setting the DELTA (difference between channels),
if you attempted to change the type of input and the measuring range, setting the
difference between channels is released, thereby the type of input and the measuring
range in the destination channel are returned to their original settings, and the span is
returned to its initial value.
• RRJC (Remote RJC, available for instruments with the optional MATH function, only)
Reference channel (RJC): Within the setting range of reference channel No.
TC (thermocouple) must be selected as the type of input to the reference channel.
If the channel No. or type of input for the reference channel, or the type of
thermocouple is changed, the alarm function will be turned OFF.
If the type of input for the reference channel or the type of thermocouple is changed,
the RRJC settings will be cleared and the type of input and measuring range for the
reference channel will be set to the one which was in effect before the change was
made. The span will be set to the initial value of the measuring range.
Setting the Span
The measurement range is decided according to the type of input. The left and right
span must lie within the measurement range. However, the span is 0 to 1 for the DI input
type. By setting the span, the setting range for the upper/lower alarm limit of the rate-of-
change is determined. The value on the left side of the SPAN menu shows the left span,
and the value on the right side of the SPAN menu shows the right span.
For the remote RJC, the setting range for span is the same as that for the reference
channel.
