Combining four tools in one, the phd Telecommunicator integrates the features of a butt set, hands-free monitor, signal-level meter, and digital multimeter. The lcd shows tone and pulse digits, including on/off time, decibel level for tones, pulses per second, and interdigit time. The unit monitors the line status (on or off hook), zero-volt intervals, and non-dtmf voice band tones. The multimeter measures AC and DC voltage to 199.9V and DC current to 199.9 milliamperes.
