Introduction

The DPG4000 combines the high accuracy of digital electronics with
the convenience and ease of use of an analog test gauge. Accurate to
± 0.05% FS, the DPG4000 can be used as a calibration reference, or
in any application where high accuracy pressure measurement is
required.

Many user configurable functions have been designed into the
DPG4000 including sampling rate, TARE, damping, auto shut off, and
min-max. Once the gauge is configured, settings can be locked and
password protected to prevent unauthorized changes to configuration.

to the next function. Once a function has been set, press ENTER to
exit the configuration menu, or CONFIG to continue with further
configuration. In order, the configuration menu and operation is as
follows:

1. Engineering Units set. The unit is shipped configured to display

PSI. By pressing the ▲ and ▼ (ZERO and MAX/MIN) keys you
can scroll forward and backwards through the 18 standard
engineering units plus a one custom unit/scale. When the desired
unit is displayed, press ENTER or CONFIG. Pressure will now be
displayed in the chosen engineering units.

See the Specifications section of this manual for a list of available
engineering units. See the Supervisory Mode section for details on
setting up custom units.

2. Set Auto Off. The auto-shut off can be set in 1 minute increments

from 1 to 30 minutes or “off” (continuous operation). The unit is
shipped set for 30 minutes. Use the ▲ and ▼ keys to set the
desired interval. The “off” setting is at the low end of the choices,
below 1 minute.

3. Display battery voltage. Actual voltage and a percent of life

bargraph indicate battery condition

4. Display actual temperature. The DPG4000 is temperature

compensated, this displays the temperature measured by the
internal sensor. The value can be set to degrees F or degrees C
using the arrow keys.

5. Set damping. Choices are “on” and “off” set with the ▲ and ▼

keys. Turning damping on will smooth readings from pulsating
pressure sources.

6. Set sample rate: This determines how often pressure is sampled

and the display is updated. Choices are 0.5, 1, 3, and 10
samples/second. Note that 10/sec provides the fastest response
time.

7. Set TARE. This allows you to set a constant offset value, which is

then subtracted from the measured pressure. For example if a
TARE is set at 30 PSI, and the measured pressure is 37 PSI, the
displayed value will be 7 PSI.
A pressure of 27 PSI would be displayed as –3 PSI.

The tare value is set manually with the ▲ and ▼ keys, and is
based on the engineering units and resolution selected for display.
TARE value can be set to the maximum range of the gauge.

The bar graph will always display the actual pressure based on the
full range of the gauge regardless of the tare setting. This is done

for safety to insure that even with a “0” reading that pressure is
being applied to the gauge.

8. Function Lock: Access to each of the settable parameters above

can be turned “off” once set, to prevent unauthorized changes to
configuration. This is accomplished through a password protected
“supervisory mode”. Press ENTER to access the supervisory
mode, or CONFIG to return to normal operation.

Supervisory Mode

Press ENTER when “FUnC LOCK” is displayed, 0PWRD will be
displayed on the gauge. The password to enter supervisory mode is
101, set using the ▲ and ▼ keys. Holding a key continuously will
cause the display to advance more quickly for faster setting. The
password is factory set and cannot be changed

1. Your DPG4000 is shipped from the factory with all setting access

“unlocked” or available to be changed.

2. In supervisory mode each of the parameters can be locked or

unlocked using the ▲ and ▼ keys. Select LOC (lock) for those
parameters you do not want to be accessible, and UnLOC (unlock)
for those can be accessed.

3. In order, the functions that can be unlocked, locked or accessed

are:

• Zero function (enable/disable)

• Set pressure units (enable/disable)

• Auto shutdown adjustment (enable/disable)

• Damping settings (enable/disable)

• Sample rate setting (enable/disable)

• Tare setting (enable/disable)

• Custom engineering units (set scale factor)

4. Use the CONFIG key to scroll through the above choices, and the

▲ and ▼ keys to lock and unlock features. Press CONFIG to
continue scrolling through the parameters, pressing ENTER at any
point saves your settings and returns the gauge to normal
operation.

When a function is “locked, it cannot be accessed or changed
from its current state. To change a locked function, enter the
supervisory mode, and unlock the function. Once it is changed,
you may enter supervisory mode to lock access again.

5. Setting a custom engineering unit or scale: The last menu choice

in supervisory mode is SET FACTR. This allows you to set a
multiplier factor from 0.001 to 100, creating a custom scale. The

5

6

set factor will be multiplied by the PSI measured, the result will be
displayed.

For example: 40 PSI is the equivalent of 1000 lbs of product in a
tank. You want to display the product weight , using a 100 PSI
gauge. By setting a factor of 25, a 40 PSI pressure would display
as 1000 (40 x 25). The engineering unit displayed on the
DPG4000 will be “Cust”.

Normal Operation

Turning the backlight on and off: Press the ENTER button.
Zeroing the display: Press and hold the ZERO button.

MAX/MIN: The DPG4000 stores minimum and maximum pressure

values in memory. Pressing the MAX/MIN button once will display the
minimum pressure from memory. Pressing the MAX/MIN button again
will display the maximum pressure from memory. After about 2
seconds, the gauge returns to normal (live display) operation. To clear
the MAX/MIN memory registers, press and hold the MAX/MIN button
for 2 or more seconds until “CLr” is displayed.

The analog bar graph at the bottom of the display indicates the applied
pressure level relative to the full range of the gauge. Keep in mind that
if a TARE value has been programmed into the gauge, the displayed
pressure will not reflect the true pressure applied.

Changing the Batteries

WARNING

Explosion hazard

Batteries must only be changed in an area known

to be non-hazardous.

Grasp the face ring on the DPG4000, turn it approximately ¼ turn
counterclockwise and remove. The face of the gauge can now be
lifted to expose the battery holder. Take off the battery hold clip and
remove the batteries. Install three AA batteries noting proper polarity.
Note: Use ONLY AA size batteries and be sure to reinstall the battery
holder retaining clip. Reassemble the case making certain that the face
is properly oriented.

If you purchased the optional 24 Volt powered version, the terminals for
power input are located on the rear of the gauge. To apply power
simply connect 24 volts to the rear terminal block taking care to
observe proper polarity.

WARNING

Gauges ordered with the external power option will not come with
batteries installed. Batteries MUST NOT be installed when
operating on external power. External power option gauges are not
approved for hazardous location use.

Battery life

Battery life is about 1500 hours (60 days) of continuous use with the
backlight off. With intermittent use, batteries could last a year or more.
There is a low battery icon in the upper left of the display. It will appear
when battery level is low. Replace batteries per recommendations
found in the specifications section of this manual.

RS-232 Interface

An RS-232 interface is standard on the DPG4000. Serial
communication can be used for configuration, calibration, and to
transfer measurement data from the gauge. For detailed specifications
on the interface and software communication, see pages 14 and 15 in
this manual.

WARNING

The RS-232 interface must not be used in hazardous areas.

Appendix 1: DPG4000 Calibration Procedure

Overview

Calibration adjustment of the DPG4000 is performed electronically via
internal software with the case closed. There are no mechanical
adjustments; all calibration commands and adjustments are done via
the keypad, using the display to guide the user through the calibration
process.

Eight calibration points are used in the adjustment program, working
from full scale to zero at pressures equaling 100%, 87.5%, 75%, 62.5%,
50%, 37.5%, 25%, 12.5%, and 0% of full scale plus vacuum.

Note: This is an ambient temperature calibration, and should be
performed at an ambient temperature of 23° C ± 3° C (72° F ± 5° F).
Calibration outside this temperature range will invalidate the
temperature compensation program in the DPG4000.

Calibration Interval

You should check performance of the DPG4000 at the interval
required by your calibration program. We recommend adjustment
when measurement deviates by more than 75% of the specified
accuracy, or 0.04%

Test Equipment

Verification and calibration of the DPG4000 requires pressure and/or
vacuum standards able to produce and indicate pressures from
vacuum to the full-scale range of the unit under test. In order to
maintain the specified accuracy of the DPG4000, standards should
have a TUR of 4:1 or better.

Connections:

The DPG4000 uses a 1/4 NPT male connection in the pressure input
port. Various adapters may or may not be needed to connect to the
pressure standard. Always make sure the hose, tubing, and fittings etc
have a rated working pressure at or above the pressure of the unit.
Also it is important that there be no leaks when performing calibration;
use Teflon tape where appropriate.

Entering Calibration Mode:

After you have made your connections, turn the power on while
holding the CONFIG key. Use the arrow keys to enter the password.
The password is 101. If you have entered calibration mode correctly
the display should look as shown below. The pressure value displayed
will be the full-scale value of the gauge.
