Telephone Test Set TS19

The Fluke Networks 19800009 TS19 is a telephone test set designed for in-house telecom technicians. It detects dial tone and polarity, places and receives calls, and offers both tone (DTMF) and pulse operation. High-impedance DataSafe monitor mode prevents accidental disruption of data lines. A polarity LED indicates correct tip and ring connection.

Compatibility Check

Verify that the line under test operates within a 48 VDC nominal loop with a 2.4 kO maximum loop limit. The unit draws a minimum of 15 mA loop current and presents 150 O typical DC resistance at 80 mA in talk mode. AC impedance in monitor mode is 600 O at 1 KHz. Angled bed-of-nails clips are included for secure line access.

Ideal User Profile

Suits technicians needing a value-priced set for basic telephone line verification, polarity checks, and call placement without disturbing active data circuits. Not suited for buyers who require advanced cable certification, network bandwidth testing, or fiber optic diagnostics. Also not for users needing a ruggedised housing rated for harsh outdoor environments.

Questions about this item

What comes with the TS19 test set and do I need a separate power source?

The set includes the handset with angled bed-of-nails clips and an integrated polarity LED. It draws loop current from the telephone line itself, so no external battery or power supply is required.

Which version of the TS19 should I choose for standard analogue line testing?

Model 19800009 is the single configuration offered. It supports both tone (DTMF) and pulse dialling, talk and monitor modes, last-number redial and DataSafe high-impedance monitoring.

What does the 2.4 kO loop-limit figure mean when I clip onto a live line?

It means the tester will operate correctly on loops up to 2.4 kO at 48 VDC, which corresponds to the nominal 15 mA minimum loop current needed for talk mode.
