Description
|
Simpson’s Model 8455 Line Loop tester detects line shorts, opens and multiple ringers, DC voltages and loop resistance. It has the capability to measure DC volt-age up to 100 volts and loop resistance to 2 megohms. A front panel “reverse polar-ity” switch is featured allowing you to change polarity positions quicker and easier than manually switching test leads when making line checks. This switch is also field replaceable thereby enabling your loop tester to be operational at all times without costly shop repairs. The compact durable construction of the tester ensures continued accuracy even under the most rugged field conditions.
