 Filter selection
This device is equipped with 5 internal time constant filters.
Select “Filter Selection” with the
MODE
key. The message is displayed for 1 sec.
and then the current setting mode is displayed. Select a time constant filter with the
▲
▼
keys.
No filter
Time constant : 25ms
Time constant : 250ms
Time constant : 2.5s
Time constant : 5s
Time constant : 10s
Use this function when pressure fluctuation is sharp and display, comparator output and analog
output are unstable.
The selected time constant filter is reflected on comparator/analog output as well.
 Analog output scaling
This function sets the pressure values for analog output zero point (1VDC)/analog output span
point (5VDC) as
a percentage (Where pressure range is from 0.0 to 100.0%F.S).
Use key to display setting of [Analog output zero point] / [Analog output span point].
1. After is displayed for 1 second, the current pressure value setting for analog
output zero point (1V) of analog output scaling. is displayed as a percentage (
Where
pressure range is from
0.0 to 100.0%F.S). With
▲
▼
keys, set a pressure value as a
percentage.
2. After is displayed for 1 second, the current pressure value setting for analog
output span point (5V) of analog output scaling. is displayed as a percentage (
Where
pressure range is from
0.0 to 100.0%F.S). With
▲
▼
keys, set a pressure value as a
percentage.
Analog output scaling is set by following the procedures described above.
Example) When analog output is 1～5 VDC for the pressure range 0.00 - 5.00MPa (0.0
～100.0%F.S.), perform scaling so that it will be "Analog output is 1～5 VDC for the
pressure range 0.00 - 4.91MPa (0.0～98.1%F.S.)".
Pressure value for analog output zero point 0.0 → 0.0 (%F.S.)
Pressure value for analog output span point 100.0 →98.1 (%F.S.)
