00:13The Jonard PT300 Pocket Continuity Tester and Toner is the perfect tool for testing continuity and short circuits and for
00:22identifying coax cables in an MDU accurately up to 5,000 feet.
00:27This industry standard now features two innovative improvements.
00:32It has been redesigned with a built-in on-off switch located within the barrel of the toner to save
00:38on battery life,
00:39and it also features voltage protection up to 52 volts, saving the tool from being shorted out.
00:46The PT300 uses a standard AAA battery and is equipped with an LED located on the head of the DC
00:53transmitter that will light up when it detects a short circuit.
00:56It also comes standard with a detachable tone detector and a bi-gender connector.
01:03To use the PT300, unscrew the tone detector from the bottom of the base of the transmitter.
01:09By removing the tone detector, the unit is now turned on.
01:13The main body of the PT300 houses the DC transmitter and has an F push-on fitting.
01:20Attach the F push-on fitting to a female F fitting port which is commonly found on wall plates in
01:27houses and apartment buildings.
01:29If the LED lights up without the tone detector connected to the other end of the cable, it either means
01:36you have a short or a splitter is attached to the end of the cable.
01:40You will not be able to tone out the cable unless you eliminate the short or disconnect the cable from
01:46the splitter.
01:47If no light appears, it means you have an open cable which can easily be identified using the detachable toner.
01:54Touch the toner to each of the cables at the remote end.
01:58When you find the correct cable that is hooked up to the transmitter, a tone will sound.
02:02The LED on the transmitter will light and you have correctly located the cable.
