Description Of Procedures - GE Druck DPI 610 User Manual

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 (1.0 inH
to 10000 psi).
Calibrator versions of this instrument contain pneumatic or hydraulic pressure
generation components to produce pneumatic pressure ranges between -1 to 20 bar (-
14.5 psi to 300 psi) and hydraulic pressure ranges up to 400 bar (6000 psi)
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 RS232 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

The procedures apply to both the DPI 610 IS and the DPI 615 IS instruments unless
otherwise stated. In the procedures in this manual, hard (fixed function) and soft
(variable function) key operations are shown in bold type : TASK and F1. These
statements mean press the TASK key and press the F1 key. Soft key operations can be
assigned 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 that 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.
