An economical solid-state TDR with octal plug-in base, the ATC 319 maintains excellent repeat accuracy despite wide voltage and temperature variations, even after long periods of down-time. One model has five dial-selected adjustable ranges and provides any timing period between 0.02 SEC and 30 MIN; Lower-cost models incorporate three dials elected ranges or a single adjustable range.


Wide Choice of Ranges: In addition to the short ranges expected of an electronic TDR, the 319E is also available with ranges as long as 100 minutes, for AC or DC operation. An unusually versatile model, the 319E five ranger has five dial-selected ranges-from 0.3 sec to 30 min-and provides any dial-adjustable timing period between 0.02 seconds and 30 minutes; (1, 10 and 100 sec and 10 and 100 min). A single 319E model thus accommodates the needs of a wide range of applications, allowing the user to select-easily and precisely-an appropriate range to permit optimum setting accuracy. The dial face automatically displays the selected range. The 319 offers a choice of five dial-adjustable fixed ranges between 1 sec. and 30 sec.

* Dial selected adjustable ranges: 0.035 - 1.0 sec,
  0.18 - 10 sec., 1.8 - 100 sec
* Dust, moisture and impact-resistant molded plastic case

The ATC 314B is an economical multi-range solid-state TDR with two models; one for off-delay (delay-on-break) and one for interval-on-delay operation. With three dial-selected adjustable ranges, it provides any timing period between 0.035 and 100 SEC with excellent repeat accuracy even with wide changes in voltage, temperature and reset time.
OFF-DELAY MODEL: Presuming the AC line is energizing the unit continuously, when the start switch is closed the relay energizes, the pilot light goes on and the unit resets. Opening the start switch begins the timing cycle. A relaxation oscillator runs at a rate determined by the set pot. When the oscillator count is equal to the level set by the range switch, a digital count circuit is satisfied and the unit times out.
At time out, the timing circuit and relay are de-energized and the pilot light goes off. Closing the start switch resets the unit. After a power failure (or on first startup) the unit will go to the timed out condition (relay de-energized) until the unit is reset by closing the start switch to begin a new cycle.

INTERVAL-ON-DELAY MODEL: Timing begins when the start switch is closed; simultaneously the relay is energized and the pilot light goes on. Either a momentary/sustained start or a sustained start input can be used (see wiring). Reset is accomplished by de-energizing the unit. At time-out, the timing circuit and relay are de-energized and the pilot light goes off.

A single 339 model thus accommodates the needs of a wide range of applications, allowing the user to select easily and precisely-an appropriate range to permit optimum setting accuracy. The dial face automatically displays the selected range.

Cycle Progress Indication: The 339’s LED annunciator provides a unique and effective method of cycle progress indication. Off before timing, the LED blinks at an ever-increasing rate as the cycle progresses; once every 3 1/2 seconds during the first 10% of the cycle, twice during the second 10%, and so on. At time-out, the LED stays on constantly, pulsing at a high rate. (In the 1 and 10-second ranges, the LED is off before timing, steady on during timing, and pulsing on after time-out.)

High Accuracy: The 339’s timing circuit is not a simple RC circuit, but utilizes the sophistication of a proprietary integrated circuit that includes counting technology along with a stable oscillator to provide repeatable time delays.

Multiple Timing Modes: Every 339 can be used for either on-delay or interval timing operation. The timing mode is selectable by a switch on the 339A housing.
