Pressure Range
Depending upon the configuration of the instrument the TRAQC-8 can be equipped with one,
two or three pressure sensors.
In instruments with two or three sensors the user can select the pressure range by pressing the
‘UP’
-or
‘DOWN’
,
‘ARROW’ key in “measuring mode”
Not all operating modes support the ‘UP’ or ‘DOWN’ keys for selecting the pressure
range. To change the
pressure range you can also select the option ‘pressure range’ in
the ‘pressure setup’ menu.
Depending upon the operating mode the range selection menu offers different possibilities.
2.11.1
Electric in- or output active
When the instrument is also measuring an electrical signal only one
pressure input can be used. By using the
‘ARROW’ keys,
select the
desired pressure sensor and press ‘ENTER’ key (F1) to confirm, press
the ‘BACK’ key (F3) to cancel.
2.11.2
Electric in- or output not active
When the electrical input are not active an instrument with more than
one sensor can show the measured value of two pressure inputs.
In this situation the pressure range menu can be used to switch the
individual ranges on or off.
2.11.3
Selecting Pressure sensor Auto ranging
The TRAQC-8 can also be equipped with two pressure ranges and one pressure connection for
measuring test pressure. The TRAQC-8 is configured to automatically switch the measuring
range.
When the test pressure exceeds 101% of the low measuring range the TRAQC-8 will
automatically switch from the low pressure range to the high pressure range. If the test
pressure is lower than 99% of the low pressure range it will automatically switch back to the
low pressure range.
This auto ranging feature will be automatically be enabled when the TRAQC-8 is switched on.
Auto ranging instruments cannot display the measured value from both sensors at the same
time, only the pressure from the selected sensor will be displayed.
