TDC voltage up to 100 volts and loop resistance to 2 megohms. Simpson’s Model 8455 Line Loop tester detects line shorts, opens and multiple ringers, DC voltages and loop resistance. It can measure DC voltage up to 100 volts and loop resistance to 2 mega ohms.
A front panel "reverse polarity" switch allows changing polarity positions quicker and easier than manually switching test leads when making line checks. This switch is field replaceable, enabling your loop tester to be operational at all times without costly shop repairs. The compact durable construction of this tester ensures continued accuracy even under the most rugged field conditions.
Features:
Allows operator to get back to the job quickly with less downtime. The replacement toggles or
push buttons can be kept in the truck and replaced on site, keeping the unit in service, at all times.
Accurately checks line shorts, opens and multiple ringers.
Measures DC voltage 0-100V and resistance R x 1, R ÷ 10.
Polarity toggle switch eliminates manually switching test leads when conducting line checks.
Durable, compact (5-1/2" x 2-3/8") construction makes it portable, easy to store and rugged.
