Tester Tempo Compact DSP, Mills

The Compact DSP Test Set from Tempo is designed to operate safely in situationswhere telephone wiring may be carrying digital traffic, voltage feed toremote electronics or the hazardous voltages that result from faultconditions or misuse of the cable.

When set to OFF mode, on connection to a circuit,the test set soundsan alarm to alert the user to the presence of voltages above 75V DC(nominal). These voltages are normally present on circuits carryingdigital services. If the circuit is active, the user can select MONITORmode and listen to the sound to determine if the circuit is carryingdigital services without disrupting the traffic.

Selecting TALK mode will stop the alarm signal and loop the line withoutdamage to the test set. If the alarm signal persists, it indicates thatthe voltage on the line is above 120V (nominal). In this case the line isnot looped avoiding damage to the test set as well as alerting the userto the presence of voltages.
