INTRODUCTION Summary of Functions

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.

Important Notice

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 TAS K 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

Cal Mode (DPI 615 versions only)

Cal mode, which is available in tasks P-I, P-P, P-V, P-P, P-DISPLAY and P-SWITCH, provides a method of setting up test parameters manually. Downloaded test procedures can also automatically set up and turn on the Cal Mode function. The method of turning on and setting up Cal Mode is shown below for a P-I task. A similar method can be used for all the other tasks applicable to the Cal Mode function.

Pressing the F1 key (TURN ON CAL MODE), provides the set-up screen for the CAL mode. Initially, the cursor is placed in the UUT SPAN field to allow the required span range to be entered. The corresponding values for the UUT output parameter (current) are then set, followed by the maximum error value and error type (%rdg or % span). When all test parameters have been set-up, the screen changes to display the input and output and the test results. The test result can only be displayed to within a range of ±9.99%. If the test result is outside this range, either the left pointing (-ve error) or right pointing (+ve error) chevrons are displayed. Within this error band, the actual tolerance value is displayed. Test results can either be stored as snapshots or logged as data log files, depending on how the instrument has been set-up.

Basic Mode (Task BASIC)

This instrument will power-up in this mode the first time that it is used. To select BASIC from any other task, press the TA SK key and select BASIC and press the ENTER key.
