DB-2D with RS232 OPERATOR’S MANUAL After use When you have finished heating samples, remember that parts of the unit – the tubes, blocks and associated accessories – may be very hot. Take the precautions listed earlier. Guarantee The unit is guaranteed against any defect in material or workmanship for the period specified on the enclosed guarantee card.
DB-2D with RS232 OPERATOR’S MANUAL Introduction Veuillez lire attentivement toutes les instructions de ce document avant d’utiliser l’appareil. Avertissement DANGER DE TEMPERATURES ELEVEES : les opérateurs peuvent subir de graves brûlures et les matériaux combustibles risquent de prendre feu.
DB-2D with RS232 OPERATOR’S MANUAL 6. Les symboles situés sur ou à côté de l’interrupteur de l’appareil ont la signification suivante : I : arrêt O : marche Après utilisation Lorsque vous avez fini de chauffer les échantillons, n’oubliez pas que certaines parties de l’appareil - les éprouvettes, leurs supports et autres accessoires - risquent d’être très chaudes. Il est donc recommandé de toujours prendre les précautions citées plus haut.
DB-2D with RS232 OPERATOR’S MANUAL Einleitung Bitte lesen Sie diese Bedienungsanleitung komplett bevor Sie dieses Gerät benutzen. Warnung HOHE TEMPERATUREN SIND GEFÄHRLICH: sie können dem Bediener ernsthafte Verletzungen zufügen und brennbare Materialien können sich leicht entzünden. Techne hat bei der Konstruktion dieses Gerätes sehr darauf geachtet, daß der Bediener vor Gefahren geschützt ist.
DB-2D with RS232 OPERATOR’S MANUAL Nach dem Gebrauch Vergessen Sie nicht, daß Teile des Gerätes (die Gefäße, die Blöcke und andere Zubehörteile) nach dem Erhitzen von Proben noch sehr heiß sein können. Bitte beachten Sie die oben genannten Vorsichtsmaßnahmen. Garantie Die Garantiedauer des Gerätes ist auf der beiliegenden Garantiekarte angegeben und schließt Fehler im Material oder der Verarbeitung ein. Die Garantiedauer beginnt am Tag des Einkaufs.
DB-2D with RS232 OPERATOR’S MANUAL Introducción Le rogamos lea cuidadosamente la información contenida en este folleto antes de manipular el aparato. Aviso LAS TEMPERATURAS ELEVADAS SON PELIGROSAS: pueden causarle graves quemaduras y provocar fuego en materiales combustibles.
DB-2D with RS232 OPERATOR’S MANUAL 6. Los símbolos que se encuentran en o cerca del interruptor de alimentación tienen los siguientes significados: I : Interruptor principal encendido O : Interruptor principal apagado Después de su uso Cuando haya finalizado el calentamiento de muestras, recuerde que las piezas del equipo, tales como tubos, bloques y demás accesorios, pueden estar muy calientes. Tome las precauciones mencionadas anteriormente.
DB-2D with RS232 OPERATOR’S MANUAL THE DRI-BLOCK® Please read all the information in this manual before using the unit. Techne's Dri-Block® heaters provide a safe, dry, constant temperature source in the laboratory. You can use the units for incubation, boiling, inactivation, wet ashing, sample concentration, enzyme analysis and many other clinical and industrial purposes.
DB-2D with RS232 OPERATOR’S MANUAL SPECIFICATION The DB-2D Dri-Block® This unit has a recessed chamber which can hold one or two interchangeable insert blocks which accept test tubes or other sample containers. The Temperature is set by 3 front panel buttons with digital display. The DB-2D is supplied with an extraction tool for removing the insert blocks from the unit and two plastic half blocks for reducing heat losses when only one aluminium block is used.
DB-2D with RS232 OPERATOR’S MANUAL Working Environment The Dri-Block® units are designed to work safely under the following conditions: Ambient temp. range 5°C to 40°C Humidity Up to 95% relative humidity, non-condensing Note: The control specifications are quoted for an ambient temperature of 20°C for units fitted with 2 insert blocks type F3506. The specification will be closely held if the ambient temperature is in the range 10°C to 30°C.
DB-2D with RS232 OPERATOR’S MANUAL OPERATION Preparation 1. Select the insert block(s) appropriate to the application. A list of available blocks is given on page 20 of this manual. Ensure that both the underside of the block(s) and the top of the hotplate are clean; efficient heat conduction between these two surfaces is essential. Top view showing two insert blocks in place 2.
DB-2D with RS232 OPERATOR’S MANUAL The Overtemperature Cut-out In the event of a fault occurring which could cause the heater to remain on, power is removed from the heater when the block temperature reaches approximately 110°C. When you Switch On When you first switch on, the display will show the edition of the software which your unit uses. For example software issue "1" would be shown as follows: It will display this for 1 second, then the actual temperature of the platten will be indicated.
DB-2D with RS232 OPERATOR’S MANUAL The DOWN ARROW Button When the SET temperature button is held down and the DOWN ARROW button is pressed, the set temperature is decreased. Speed of Change of Set Temperature Each press of the UP ARROW or DOWN ARROW buttons will increase or decrease the set temperature by 0.1°C.
DB-2D with RS232 OPERATOR’S MANUAL Over-Temperature Indicator If the unit should, for any reason, exceed the temperature set for the overtemperature cutout (see page 16), the over-temperature indicator will light. The heater will have been switched off and the unit will begin to cool even if the heater light is on (the light staying on or not depends on which circuit has sensed an over-temperature).
DB-2D with RS232 OPERATOR’S MANUAL After Use 1. When you have finished heating samples, remember that parts of the unit – the tubes, blocks and associated accessories – may be very hot. Take the precautions listed earlier. We recommend that the blocks should be allowed to cool to 70°C before being removed from the Dri-Block®. They will still have to be handled with care 2.
DB-2D with RS232 OPERATOR’S MANUAL ADDITIONAL INFORMATION Insert Blocks Insert blocks are made of aluminium alloy and must be ordered separately from the heater units.
DB-2D with RS232 OPERATOR’S MANUAL Operator Maintenance NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY PROPERLY TRAINED PERSONNEL. REMOVING THE SIDE, FRONT OR REAR PANELS EXPOSES POTENTIALLY LETHAL MAINS VOLTAGES. THERE ARE NO OPERATOR MAINTAINABLE PARTS WITHIN THE EQUIPMENT. In the unlikely event that you experience any problems with your Dri-Block ® which cannot easily be remedied, you should contact your supplier and return the unit if necessary.
DB-2D with RS232 OPERATOR’S MANUAL Calibration Remember that if you change the calibration from that set at the factory you may change the calibration at all temperatures. You may get different calibration with different blocks. Make sure that you have good thermal contact between the blocks and the heater platen in the Dri-Block. In order to ensure that the calibration you are setting is correct, you will need to use an independent calibrated probe or thermometer.
