Vout: 0 to 5V

Pin 2 (GND)
Figure 3: Example configuration: Vout
Operation - 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
"Operation - Menu: Supply voltage output (Vout)").
If the pressure ranges for the DPI 104 and the external
pressure regulator are different, you must set an
applicable scale factor (0.01 to 9.99).
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:
Scale factor = 100/200 OR 1500/3000 = 0.5
Vout register (%)
= (25/200) * 100 OR (375/3000) * 100
(DPI 104)
= 12.5%
To get a 25 bar (or a 375 psi) line pressure, the DPI 104 uses
these values to supply the Vout value shown below:
Vout = ( 12.5/100 * 5V ) / 0.5 = 1.25 V
Operation - Menu: Set automatic power OFF
Use this function to save battery power. The power goes
off a specified period after the last button or external
software operation. To get the maximum battery life, we
recommend you use this function.
Note: The DPI 104 uses a small quantity of power while it is
OFF. If you put it into storage for a long period, disconnect
the battery (refer to "Installation").
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 "To start - Menu
operation".
Note: If continuous operation is important, set this function
to OFF and use an external power supply.

Operation - Menu: Set lock code
Use the lock function to prevent accidental changes to the
configuration. There are two options:
• Lock code < 500: This locks the menu and the tare
function. Factory code = 000
• Lock code > 499: This locks the menu but you can still
use the zero option to set a tare value.
Refer to "Operation - Menu: Set tare".
Lock code - Set up and use
Menu: Set this function to On (Refer to "To start - Menu
operation"). Then use these steps to set a new code.
Lock 1
Digit = 0 or 9
3. To finish the lock code, repeat steps 1 + 2 for each digit.
The next time you want to change the menu options, the
display shows: L - - -
Enter the applicable code. To reset the code to the factory
code, you must do a restore operation. Refer to
"Maintenance".
Operation - Menu: Set scan rate
Use the scan rate function to set the rate used to update
the maximum/minimum values.
Note: When you increase the scan rate, you increase the
power consumption. The maximum/minimum function
updates its data at five times the specified scan rate.
The rate for the normal pressure display is always 2 Hz.
Scan rate - Set up and use
Menu: Set an applicable value in the range 2 to 10 Hz. Refer
to "To start - Menu operation".
Operation - Menu:
Use this function to read the pressure from an external
IDOS UPM. The calibration function is not available but you
can use all the other DPI 104 pressure functions. Example:
Set tare, Monitor maximum/minimum.
This function does not supply power to the IDOS UPM. To
use it, you must have the optional external IDOS UPM
connection + power supply. This optional accessory uses
the RS232 connections in the 8-pin connector (Table 3).
Monitor external IDOS - Set up and use
1. Connect the instrument (Figure B2).
2. Menu: Set this function to On (Refer to "To start - Menu
operation").
3. If necessary, set the applicable additional functions
specified in this manual.
