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.
