1 K249 Issue No. 4EnglishGeneralThe DPI 610 IS and DPI 615 IS intrinsically safe instruments measure and displaypneumatic and hydraulic pressure applied to the test port . Pressuremeasurement can be absolute, gauge and sealed gauge and in ranges from 2.5mbar to 700 bar.Calibrator versions of this instrument contain pneumatic or hydraulic pressuregeneration components to produce pneumatic pressure ranges between -1 to 20bar and hydraulic pressure ranges up to 400 bar.Using external electrical connections, the DPI 610 IS and DPI 615 IS intrinsicallysafe instruments measure ±30 volts d.c. and ±55 mA. An integral sensor providesmeasurement of ambient temperature. Additional sensors (option B1) connect toan external connector and extend the pressure measurement range and includedifferential pressure measurement. The DPI 615 instrument has an RS 232connector to enable downloading of test data to a compatible documentingsystem. Six alkaline C size batteries, IEC Type LR14, power the instrument .Important NoticeZinc-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 ProceduresIn 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. Thesestatements mean press the TASK key and press the F1 key. Soft key operationscan be allocated to both the F1 and F2 keys. Where a specific soft function isreferred to it is written in bold italics (e.g.) PROCESS.This instrument has a number of operating modes which are described insimplified form in the following sections. Diagrams accompanying the proceduresgive typical selection sequences and shaded controls indicate that this control keyshould be pressed in the appropriate sequence. Diagrams should be read from leftto right, top to bottom where appropriate. A shaded display soft box indicatesthat the function key immediately below that soft box should be pressed (either F1for 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 requiredoption. (If all keys shaded, use all these keys to select or enter data).(c) Press the ENTER key.INTRODUCTION Summary of Functions
