TRAQC-8 DPC
TRAQC-8 DPC 11/2016 EN Rev.3
Sheet 20
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.
3.11.1
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.
3.11.2
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.
3.11.3
Selecting Pressure sensor Auto ranging
The TRAQC-8 DPC can also be equipped with two pressure ranges and one pressure connection for
measuring test pressure. The TRAQC-8 DPC is configured to automatically switch the measuring range.
When the test pressure exceeds 101% of the low measuring range the TRAQC-8 DPC 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 DPC 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.
