General
1. Introduction
1.1 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
2
O 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 V dc 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.
1.2 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.
INFORMATION
Zinc-carbon and zinc-chloride cells must not be used in this
instrument. Use only the battery types as shown in “Batteries” on page ii.
