b. Setting Calibration Range Lower
Range Value and Higher Range Value
(C21: LOW RANGE, C22: HIGH
RANGE)
These range values are set as specified in the order
before the instrument is shipped. Follow the procedure
below to change the range.
• The measurement span is determined by the high and
low range limit values. In this instrument, changing
the low range value also automatically changes the
high range value, keeping the span constant.
• Example 1: With present settings of 0 to 30 kPa,
set the lower range value to 0.5 kPa.

Span = Higher range value – Lower range value
• Note, however, that changing the higher range value
does not cause the lower range value to change.
Thus, changing the higher range value also changes
the span.
• Calibration range can be specified with range value
specifications up to 5 digits (excluding any decimal
point) for low or high range limits within the range
of –32000 to 32000.

(3) Damping Time Constant Setup

(C30: AMP DAMPING)
When the instrument is shipped, the damping time
constant is set at 2.0 seconds. Follow the procedure
below to change the time constant.
• Example: Change from 2.0 sec to 4.0 sec.

Note: The damping time constant set here is the damping time
constant for the amplifier assembly. The damping time
constant for the entire transmitter is the sum of the values for
the amplifier assembly and for the capsule assembly. For the
capsule assembly damping time constant (fixed), see the
"General Specifications" found at the end of this manual.
