Tone And Probe kit, Basic - 

The 601K-G from Greenlee Communications is a standard tone tracing kit. This basic tone and probe kit (CALM) includes 77M-G tone generator which provides talk battery supply for vacant pairs. Two distinct tracing signatures available for easier tracing and this 77M-G also includes modular plug and alligator test leads. The 601K-G also includes 200EP-G inductive amplifier which provides an industry standard tracing for voice, data and video wiring. The 200B-G has gain (nominal) of 30db, input impedance (nominal) of 100Mohm and plastic tip resistance of 300 ohm. The 77M-G has talk battery voltage (into 600 ohm) of 4.6VDC, output power (into 600 ohm) of +10dBm, resistive short visual indication of less than 10Kohm, output frequency (nominal) alternating of 890/960Hz, warbling-slow of 1.3Hz/fast: 6Hz and voltage protection (into 600 ohm) of 52VDC.
