2.0 Safety instructions

Read this manual carefully before using the instrument!

Please follow the instructions and procedures described in this manual. They are designed to allow you to get the most out of your DTI system and avoid any personal injuries and/or damage to the instrument.

Disposal – WEEE Directive

These calibrators contain Electrical and Electronic circuits and must be recycled or disposed of properly (in accordance with the WEEE Directive 2012/19/EU).

Warning

• The indicator must not be used for any purposes other than those described in this manual, as it might cause a hazard.

• The indicator has been designed for indoor use only and is not to be used in wet locations.

• The indicator is not to be used in hazardous areas, where vapour or gas leaks, etc. may

constitute a danger of explosion.

• The indicator is not designed for operation in altitudes above 2000 meters.

• Only use the specified mains adaptor approved for the voltage and plug configuration in your area.

• Do not connect rated voltages to earth with a maximum above 30V to the input terminals.

• Always position the indicator to enable easy and quick disconnection of the power source (mains adaptor).

Caution…

When connecting the PC and the indicator please ensure that both the PC and the indicator are switched off at the mains. Failure to do so may result in your equipment being damaged.

3.0 Introduction

The DTI (Digital Temperature Indicator) system is designed for fast and traceable calibration. The system is portable.

The DTI is prepared for re-calibration by your local calibration laboratories, and all necessary instructions for the re-calibration is stated in this manual.

The DTI is a precision instrument and to achieve the precision, a set of sensor coefficients relating to the specific sensor must be present in the DTI. Before use of the DTI, ensure that the correct coefficients for each channel in the DTI are equal to those from the sensors calibration certificate – see section 5.2.6.

How to install new sensor coefficients can be found in section 8.2.3.

Definitions and terminology used in this manual: a. Text inside <> refer to soft-keys on the DTI panel or keys on Text with big letters indicate the activated function if there

b. Display text on the DTI is shown inside rounded frames. c. Screen menus in the DTI software are shown inside edged

Note…

The DTI is not designed for continuously data-logging recording, since there is no guarantee for missed log values during the data-logging

4.1 Functional description

The DTI is used for measuring inputs from two RTD sensors. The two sensors are connected to the connectors in the top plate. The input signal is compared to the two internal resistor references from which the input signal can be determined.

The DTI operates with a 2*20 character display, which continuously read out the two inputs.

The input value can be shown as the actual read value for both sensors, the peak values for sensor 1 or 2, the differential value for the two sensors or as the differential peak value for the two sensors.

The input value can be shown in Ω, °C, °F or K selected by the user. The resolution in temperature can be 0.1, 0.01 or 0.001. The sensor coefficients can be inspected by the user and changed in

the software program. The power supply is made by eight 1.5 Volt batteries or a mains

adapter. Use only mains adapter supplied by AMETEK in order to comply with the requirements in EN50081-1 (1992) and EN50082-1 (1992).

It is possible to connect the shields from the cables to the cabinet, in order to reduce the influence of noise.

The DTI-1000 is supplied with RS232 and software, in order to have the possibility of saving the measured data and to recalibrate the DTI or the sensors.

4.2 Indicators

The DTI only uses the display for all indications. The display has 2*20 characters which will swap between read-out values or menu selection when requested. Please see section 5.2.1 to 5.2.7 for possible display read-outs. Please note that the error messages will also be showed in the display, see section 7.3.
