Menu: Set Vout scale
factor
When the Vout function is set to
P-V
or
US
mode, the Vout scale
factor becomes part of the Vout calculation (refer to menu
operations).
If the pressure ranges for the DPI 104 and the external pressure
regulator are different, an applicable scale factor (0.01 to 9.99)
must be set.
Example - To get a 25 bar (or a 375 psi) line pressure with:
• an External pressure regulator:
FSO = 100 bar (or 1500 psi)
• a DPI 104: FSO = 200 bar (or 3000 psi)
In this example:
To get a 25 bar (or a 375 psi) line pressure, the DPI 104 uses these
values to supply the Vout value shown below:
Menu: Set automatic
power OFF
The power goes off in a specified period after the last button press
or external software operation.
Recommendation
Use this function for maximum battery life.
Note: The DPI 104 uses a small quantity of power when OFF. For
storage, disconnect the battery (refer to menu operation, page 5).
Automatic power OFF -
Set-up and use
Menu: Set this function to
On
. Then set an applicable value in the
range 1 to 99 minutes, refer to menu operation, page 5.
Note: If continuous operation is required, set to OFF and use an
external power supply.
Menu: Set
lock
code
Use the lock function to prevent accidental changes to the
configuration. Two options are as follows:
•
Lock code < 500
: This locks the menu and the tare function.
Factory code = 000
•
Lock code > 499
: This locks the menu but the zero option to set
a tare value is still available.
Refer to menu operation, page 5.
Scale factor
= 100/200
OR
1500/3000 = 0.5
Vout register (%)
(DPI 104)
= (25/200) x 100
OR
(375/3000) x 100
= 12.5%
Vout =
( 12.5/100 * 5V ) / 0.5 = 1.25 V
