3M Dynatel 965TD DOS Terminal Emulation/Loop Analyzer Test Set

Description: 3M Dynatel 965TD DOS Terminal Emulation Test Set Comes with a 900TD Series Test Set manual, Dynatel 900 Series Test Set manual, new batteries and what you see in the pictures. If you don't see it, you probably wont get it. Specifications are from Dynatel and may vary slightly due to upgrades, options or revisions this unit may or may not have. Unit powered up and went through self-calibration just fine. Unit is guaranteed to work and comes with its chargeable Batteries. Introduction: The 900TD Series Test Sets with DOS/terminal emulation have the same testing capabilities as the non-terminal test sets. The terminal emulation option adds a QWERTY-type (touch-typists, typewriter style) programmable keyboard, larger display screen, and full duplex communications through its internal modem. Battery backed-up RAM (random-access memory) provides test data storage. Through a tip-ring connection to a working or dial-tone line, the unit's modem can dial to a telephone company computer and connect to it as a terminal. Technicians in the field can then use the test set/terminal to: Recieve workloads; Connect to various operating systems for performing tests; Transmit data to host computers; and Transmit and receive cable records information, loop assignment records, history records, customer information, mail, and time entry records. Physical Description: The 900TD Series Test Set comes in a sturdy yellow plastic case. A large LCD features a backlight, and displays sixteen lines of forty characters each. The front-panel keyboard is divided into two sections. The left side of the keyboard is used primarily when opearting in terminal mode. In terminal mode, the keys generally control at least two functions - either a second character or a function indicated above the key. The second character or function is activated by pressing nad releasing the Fn key before pressing the desired key.

Accuracies are doubled for single pair hook-up. 3Accuracy depends on correct temperature setting as well as gauge accuracy of copper. The temperature can be read by the built-in sensor or can be operator-entered.
