INTRODUCTION
General
The DPI 610 IS and DPI 615 IS intrinsically safe instruments measure and display
pneumatic and hydraulic pressure applied to the test port . Pressure
measurement can be absolute, gauge and sealed gauge and in ranges from 2.5
mbar to 700 bar.
Calibrator versions of this instrument contain pneumatic or hydraulic pressure
generation components to produce pneumatic pressure ranges between -1 to 20
bar and hydraulic pressure ranges up to 400 bar.
Using external electrical connections, the DPI 610 IS and DPI 615 IS intrinsically
safe instruments measure ±30 volts d.c. and ±55 mA. An integral sensor provides
measurement of ambient temperature. Additional sensors (option B1) connect to
an external connector and extend the pressure measurement range and include
differential pressure measurement. The DPI 615 instrument has an RS 232
connector to enable downloading of test data to a compatible documenting
system. Six alkaline C size batteries, IEC Type LR14, power the instrument .
Zinc-carbon and zinc-chloride cells must NOT be used in this instrument .
Use only the battery types as shown in the Table on page 7.
Description of Procedures
In the procedures outlined in this User Guide, hard (fixed function) and soft
(variable function) key operations are shown in bold type (e.g.) TASK and F1. These
statements mean press the TASK key and press the F1 key. Soft key operations
can be allocated to both the F1 and F2 keys. Where a specific soft function is
referred to it is written in bold italics (e.g.) PROCESS.
This instrument has a number of operating modes which are described in
simplified form in the following sections. Diagrams accompanying the procedures
give typical selection sequences and shaded controls indicate that this control key
should be pressed in the appropriate sequence. Diagrams should be read from left
to right, top to bottom where appropriate. A shaded display soft box indicates
that the function key immediately below that soft box should be pressed (either F1
for the left hand soft box or F2 for the right).
In the above diagram the following key sequence is indicated.
(a)
Press the F2 key (the key immediately below the UNITS soft box).
(b)
Use the Up and Down cursor keys (only) to select the required
option. (If all keys shaded, use all these keys to select or enter data).
(c)
Press the ENTER key.
