FLUKE Networks TS19 Telephone Test Set

The FLUKE Networks 19800003 TS19 is a telephone test set built for in-house telecom technicians. It detects dial tone and polarity while placing and receiving calls during line testing. High impedance DataSafe operation in monitor mode prevents accidental disruption of data lines. Tone (DTMF) and pulse operation with last number redial complete the feature set.

Technicians needing safe monitor mode

This set suits technicians who require high impedance monitoring to protect active data circuits during testing. It supports both tone and pulse dialling for compatibility with legacy and modern exchanges. Buyers who need advanced cable diagnostics or network signalling analysis should look at dedicated qualification tools instead.

Loop limit 2.4 kO at 48 VDC

The loop limit is 2.4 kO maximum at 48 VDC with a nominal 15 mA minimum loop current. DC resistance in talk mode is 150 O typical at 80 mA current. AC impedance in monitor mode is 600 O at 1 KHz typical in the low impedance ring position. The included leads terminate in banana jacks to alligator clips for flexible line connection.

Questions about this item

Will the TS19's banana jacks and alligator clips connect to the screw terminals on my legacy punch-down block?

Yes, the banana jacks accept the included alligator clips which can grip standard screw terminals on older punch-down blocks for quick line access.

How do I verify the TS19 is drawing the correct loop current after clipping onto a live line?

In Talk mode the set presents 150 Ω typical at 80 mA; a clear dial tone and steady polarity LED confirm the loop is above the 15 mA minimum at 48 VDC.

Does the 19800003 package include a belt clip or carrying case, or must I buy one separately?

The supplier data lists only the TS19 test set with banana jacks to alligator clips; no belt clip or case is mentioned, so plan to source one separately if required.
