Installation This section shows how to install and connect the DPI 104.
Warning: To prevent an explosion or fire, use only the GE specified battery
and external supply.
DPI 104 Battery Use the procedures in Table 4 to install or replace the battery.
Table 4: Installation procedures - Battery
DPI 104 position Attach the DPI 104 in a safe configuration that prevents unwanted
stress (for example vibration, physical impact, shock, mechanical
and thermal stresses).
To get the best installation position, turn the pressure connector
(A1: item 4) and the display bezel (A1: item 6) to give the best view of
the display (Figure B1). End stops set the limits in each axis.
CAUTION: Do not use force to turn the pressure connector or the
bezel farther than the end stops. Using force can damage the
instrument.
Step Procedure
1If applicable, set the power to off and isolate the external
power supply.
2Remove the display bezel (Figure A1.2).
3Make sure that the o-ring [A1: item 7] and the related surfaces
are serviceable. Use only original parts supplied by the
manufacturer.
4Remove the battery clamp [A1: item 10].
5If applicable, disconnect the battery connector [A1: item 8] and
*discard the used battery.
* Use an applicable recycling facility.
6Attach the battery connector [A1: item 8] to the new battery.
7Install the new battery (Figure A1.3) and re-attach the battery
clamp [A1: item 10].
8Push the display bezel [A1: item 6] back into position until it is
fully engaged.

8Installation K0394 Issue 3 - [EN] English
Pressure connections CAUTION: Do not use the body of the DPI 104 to tighten the
pressure connection, this can cause damage. Use the flat faces
on the pressure connector to hold the body and tighten the
pressure union.
Use an applicable method to seal the pressure connections, and
then tighten to the applicable torque (Figure 1 and Table 5).

Refer to menu operation, page 5.
External power Recommendation
For the following functions and operations use an external power
supply :
• Functions: Maximum/minimum, Switch, Low/high alarm, Vout,
IDOS
• Operations that use the DPI 104 for long periods.
Operation This section shows how to use the DPI 104.
Menu: Set units There are 11 different units to measure pressure, refer to the menu
operation, page 5.
Units - Set-up Refer to Safety Instructions and User Guide, publication K0387.
Menu: Set tare (or set

Use the tare function to adjust the pressure value on the display,
refer to Table 7, below.
Table 7: Permitted tare values
If a value is set that is not in the permitted range, the value goes
back to the last accepted value.
Range Permitted tare values

Tare - Set-up and use Menu: Set this function to On (refer to menu operation, page 5).
When this function is On, there are two options to set a
tare value (tA):
•Menu option: Set the menu “tOn”, then set a tAvalue:
Repeat steps 1 & 2for each digit and for the decimal point.
•Zero option: Step 1lets you set a value for tA. Press and hold.
When tAis not zero, the last segment on the analog dial flashes.
To make sure that there is an indication of the correct pressure:
While tare is On, the analog dial and % indication show values
calculated from the calibrated range without the tare adjustment.
Tare - With Lock If the menu lock is On with a lock code set < 500, the zero option is
rejected - Error code (E0002).
Tare - With Alarm
and/or Vout
If the zero option is used to set a tare value (tA) while the alarm
and/or Vout functions are On, the display counts down from:
tArE9 to tArE0.
When setting a tAvalue, the alarm and Vout functions use values
calculated from the calibrated range and the pressure value on the
display.
Tare - With FSO values To make sure that there is an indication of the correct pressure
while tare is On, the FSO Low and/or FSO High values are not used.

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:
Voltage output (Vout) -
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).
Figure 3: Example configuration: Vout
P-V: Vout is proportional to the pressure value on the display.
US: User mode. 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

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

5. Enter the applicable code.
To reset the code to the factory code, do a restore operation. Refer
to menu operations, page 5.
Menu: Set scan rate This function sets the rate that the DPI 104 uses to take pressure
samples from the internal sensor.
The nominal update rate for the display is 2 Hz. The up-date rate for
the maximum/minimum function and the switch function is greater
than or equal to the specified scan rate.
Note: Increasing the scan rate, increases the power consumption.
Scan rate - Set-up and
