Introduction

The DPI 820 Dual Input Thermometer is part of the GE Druck DPI 800 series of hand held instruments. The DPI 800 series uses Intelligent Digital Output Sensor (IDOS) technology to give instant plug and play functionality with a range of Universal Measurement Modules (UMM). The DPI 820 includes these functions:

Function

* Measure temperature: T1 and/or T2 * Measure temperature difference: T1 - T2 * Cold Junction (CJ) compensation Snapshot: Up to 1000 displays with a date/time stamp Communications port: IDOS or RS232 Language selection ** Measure pressure/Leak test: UMM - Pressure Other functions: Hold, Maximum/Minimum/Average, Filter, Tare,

Scaled values, Bac klight, Alarm

* Refer to “Specification”. ** Optional item

Safety

Before you use the instrument, make sure that you read and understand all the related data. This includes: all local safety procedures, the instructions for the UMM (if applicable), and this publication. Before you start an operation or procedure, make sure that you have the necessary skills (if necessary, with qualifications from an approved training establishment). Follow good engineering practice at all times.

• It is dangerous to ignore the specified limits for the instrument or to use the instrument when it is not in its normal condition. Use the applicable protection and obey all safety precautions.

• Do not use the instrument in locations with explosive gas, vapor or dust. There is a risk of an explosion.

• To prevent electrical shocks or damage to the instrument, do not connect more than 30V between the terminals, or between the terminals and the ground (earth).

• UMM - Pressure options only. To prevent a dangerous release of pressure, isolate and bleed the system befo re you disconnect a pressure connection.
