Introduction

The Model TMD90A dual input thermometer accepts Type K, J, T, R, S, and E thermocouples. With a triple display screen to view measurement results and relative time clock. Optional RS-232 software and cable allows collection of real time data to a PC for further analysis or reports.

TMD90A displays all LCD (liquid crystal display) segments for approximately 3 seconds when it is first turned on and then provides information on any connected thermocouples. Numerous viewing combinations are available. The LCD is divided into three distinct sections; one large (Primary) top screen and two smaller bottom screens (Secondary and Relative Clock).

The three display areas are continually updated with the temperature measurements and relative time information. There are several options regarding how and what information is presented on the LCD.

• Temperature readings are easily toggled between Fahrenheit and

Celsius.

• A backlight illuminates the LCD for viewing in low light areas.

• The A button will freeze the upper display data while allowing

the lower displays to continue updating Information.

• A low battery indicator is also displayed as appropriate.

• The meter defaults to the last mode selected when turned off.

Note: If no thermocouples are connected, four dashes(----) appear in the temperature display.

Introduction

Le thermomètre à entrée double modèle TMD90A accepte les thermocouples de types K, J, T, R, S et E. Il est doté d’un écran à triple affichage pour visualiser les résultats de mesure et l’horloge en temps relatif. Le logiciel et le câble optionnel RS-232 permettent de recueillir les données en temps réel vers un PC afin de les analyser ou de créer ultérieurement des rapports.

Le TMD90A affiche tous les segments LCD (affichage à cristaux liquides) pendant environ 3 secondes lors du démarrage avant de fournir les informations sur tous les thermocouples connectés. Diverses combinaisons d’affichage sont possibles. L’écran LCD est divisé en trois sections distinctes ; une fenêtre principale (affichage primaire) en haut et deux fenêtres plus petites en bas (affichage secondaire et horloge relative).

Les trois zones d’affichage sont actualisées en permanence avec les mesures de température et les informations de temps relatif. Plusieurs options permettent de configurer la présentation et le type des informations apparaissant sur l’écran LCD.

• Les relevés de température basculent facilement entre les unités

Fahrenheit et Celsius.

• Un rétroéclairage illumine l’écran LCD pour les lectures en zones

faiblement éclairées.

• Le bouton A gèle l’affichage de la fenêtre supérieure des

données tout en permettant la mise à jour des informations dans les fenêtres du bas.

• Un indicateur de pile faible apparaît également le cas échéant.

• L’appareil adopte par défaut le dernier mode qui était sélectionné à

la mise hors tension.

Remarque : Si aucun thermocouple n’était connecté, quatre tirets (----) apparaissent sur l’affichage des températures.
