Introduction
The DPI 880 Multi-function Calibrator is part of the
Druck DPI 8xx series of hand held instruments.
This series of instruments uses Intelligent Digital Output
Sensor (IDOS) technology to give instant plug and play
functionality with a range of Universal Measurement
Modules (UMM). Example: the Universal Pressure Module
(UPM).
The DPI 880 includes these functions:
Safety
Before you use the instrument, make sure that you read
and understand all the related data. This includes: all local
safety procedures, the instructions for the UMM (if
applicable), and this publication.
WARNING
• It is dangerous to ignore the specified limits for the
instrument or to use the instrument when it is not in
its normal condition. Use the applicable protection
and obey all safety precautions.
• Do not use the instrument in locations with explosive
gas, vapor or dust. There is a risk of an explosion.
• To prevent electrical shocks or damage to the
instrument, do not connect more than 30V between
the terminals, or between the terminals and the
ground (earth).
• UPM only. To prevent a dangerous release of
pressure, isolate and bleed the system before you
disconnect a pressure connection.
Before you start an operation or procedure in this
publication, make sure that you have the necessary skills
(if necessary, with qualifications from an approved training
establishment). Follow good engineering practice at all
times.

To start - Prepare the instrument
Before you use the instrument for the first time:
• Make sure that there is no damage to the instrument,
and that there are no missing items.
• Remove the plastic film that protects the display. Use
the tag (◗) in the top right-hand corner.
• Install the batteries (refer to B1). Then re-attach the
cover.
To start - Power on or off
To set the power on or off, press ❍(A1 - item 1). The
instrument does a self test and then shows the applicable
data.
When the power is off, the last set of configuration options
stays in memory. Refer to “Maintenance”.
To start - Set up the basic operation
Use the Set Up menu to set up the basic operation of the
instrument.
If there is additional data for a menu option, select
Settings (■■) to see the values that are set up. If
necessary, adjust the values.
Table 1: Menu options - Set Up
To start - Select a task (Measure and/or supply)
When the instrument is set up (Table 1), use the task

menu shows the applicable IDOS options.
Make the necessary selections from each area (➀and ➁).
One task is permitted in each area.
Note: Use the Dual Function area (➁) to do two operations
at the same time. If the area ➁selection is not necessary,
set this area to off (■). This saves the battery power.

We recommend that you return the instrument to the
manufacturer or an approved service agent for
calibration.
If you use an alternative calibration facility, make sure that
it uses these standards.
Calibration - Before you start
To do an accurate calibration, you must have:
• the calibration equipment specified in Table 8.
• a stable temperature environment: 70 ± 2°F (21 ± 1°C)
Table 8: Calibration equipment
Before you start the calibration, make sure that the time
and date on the instrument are correct (Table 1).
