Menu: Supply
voltage output (Vout)
Use the Vout function to supply a voltage output (0.05 to 5 V) to an
external system. Two options are as follows:
Recommendation
To save battery power use an external power supply.
P-V mode voltage
calculation
Example DPI 104: FSO = 20 bar (or 300 psi),
Vout scale factor = 1.00.
Applying 10 bar (or 150 psi) to this DPI 104:
US mode voltage
calculation
This calculation uses the values set up for the Vout register and the
Vout scale factor.
If the pressure ranges for the DPI 104 and the regulator are
different, set a new Vout scale factor (refer to menu operations).
Example - If the Vout register is set to 25%, and the Vout scale
factor is set to 0.5:

Set up and use
1. Connect the DPI 104 with the applicable Table 3 accessories:
Accessories B/C - refer to cover, Figure B2 (c).
Accessory E - refer to Figure 3, below/Table 6, page 8.
2. Menu: Set function to
OFF, P-V, US (
refer to menu operation,
page 5).

Example configuration: Vout
P-V:
Vout is proportional to the pressure value on the display.

. Set a value in the Vout register (0 to 100%) to
control an external pressure regulator.
Vout =
( 10/20 * 5V ) / 1.0
OR
( 150/300 * 5V) / 1.0 = 2.5 V
Vout = ( Vout register / 100 ) * 5V
Vout scale factor
Vout = ( 25/100 * 5V ) / 0.5 = 2.5 V
