Table 7.1 Parameter Usage and Selection
Item Description
Tag No. Sets the tag No. as Device Tag (Software Tag). Sixteen characters
(alphanumeric characters, including - and •) can be set.
Output The process variable and the diagnostic result can be output.
Either or all of differential pressure (AI1:Process Value), static pressure
(AI2:Process Value), temperature(AI3:Process Value) of capsule or
amplier and self-diagnostic information (UAPMO:Diagnostic Status) can
be set to the output
Range Adjust the range corresponding for 0% to 100%.
The unit of the range, input value at 0% (LRV) and input value at 100%
(URV) is set.
Note: LRV and URV can be set within the range of -32000 to 32000.
Damping time constant Damping time constant is used to reduce the large uctuation of pressure
signal and given by each Process Value Filter Time parameter for
differential Pressure/pressure (AI1) and Static pressure (AI2).
Output signal and integral indicator mode Sets mode for output signal and integral indicator to “linear mode”
(proportional to input differential pressure) or to “Square root mode”
(proportional to ow).
Output signal low cut mode Used mainly to stabilize output near 0 if output signal is the square root
mode. Two modes are available: forcing output to 0% for input below a
specic value, or changing to proportional output for input below a specic
value.
Integral indicator range of scale and unit Sets one of differential pressure/pressure value, static pressure value, or
temperature value for the integral indicator scale.
Note: LRV and URV can be set within the range of -32000 to 32000.
Unit for displayed temperature Sets a temperature unit to be displayed.
Unit for displayed static pressure Sets a pressure unit for the static pressure to be displayed
Direction of impulse piping connection
(which is high pressure, L side or R side)
Used where installation conditions makes it imperative to connect high
pressure side impulse line to low pressure side of transmitter.
Normally, correspond by replacing impulse line, and use this function only
when unavoidable.
Range with actual input applied Range corresponding for 0% to 100% signal is set with actual input
applied.
The output setting can be done just 100% to user’s reference pressure
output.
However, when shipping it, the calibration is done in high accuracy as for
DPharp. Please do the span setting by a usual range setting.
Zero Point Adjustment and Span Adjustment Handle Zero Point Adjustment and Span Adjustment.
There are two methods of Zero Point Adjustment, using external zero-
adjustment screw and using the device conguration tool.
Reset adjustment The amount of the adjustment set by user can be cleared.
Software write protect Prohibit writing the setting data.
Operational mode Set the operational mode of the sensor and integral indicator, etc.
Note: Some of the parameter settings are in the dialogue form called method, the on-line instructions you can congure the parameters
easily.
