RJ11 and RJ45 cable tester

This Monoprice 108138 tester checks telephone and network cables for broken wires and crossed connections. It consists of a main Master unit and a detachable Remote unit, each equipped with an RJ11 and an RJ45 jack. The tool is designed for installers and technicians who need to verify cable integrity quickly.

Battery powered with LED status display

The unit runs on a 9-volt battery that is not included with the package. Both the Master and Remote units feature a series of 9 LEDs that indicate the status of each line on the attached cable. The tester supports both a fast automatic and a slow automatic testing mode.

Portable kit with synthetic leather case

A zippered synthetic leather case is included for storage and transport of both units. The detachable Remote unit allows end-to-end cable verification without moving the Master unit. This kit suits field technicians who need a compact, self-contained solution for on-site cable troubleshooting.

Questions about this item

How do I install the 9-volt battery in the Monoprice 108138 tester and what step is often missed?

Open the battery compartment on the Master unit, insert a 9-volt battery observing the polarity markings, and secure the cover; the step often missed is confirming the battery is fresh because a weak cell will cause the 9 LEDs to display dim or erratic results.

What maintenance will the Monoprice 108138 tester need over time?

Replace the 9-volt battery when the LED brightness fades, keep the RJ11 and RJ45 jacks free of dust with occasional compressed air, and store both units in the zippered synthetic leather case to protect the contacts.

What limit appears first when testing long cables continuously with the Monoprice 108138?

Battery drain is the first limit; sustained use in either automatic mode depletes the 9-volt cell, causing the 9 LEDs to dim and eventually preventing the tester from completing a full wire-map cycle.
