The SCS CTC0623242WW WS Aware Monitor, 4.20MA Out, Standard Remotes works with dual wrist straps that have a standard 3.0 mm audio mono plug. It verifies proper wearing of a wrist strap by measuring an operator's resistance. This model detects body voltage and alarms if it exceeds the preset level, which can be changed in the field. Red LEDs indicate when wrist strap fails, when proximity sensor fails, or when wrist strap is incorrectly plugged into the visitor's jack. Green LEDs indicate that wrist straps are properly connected and worn.

The CTC062-3-242-WW also offers tool ground monitoring through tri-color LEDs that show green when ground impedance is within limits, red when ground fails, blinking yellow when EMI threshold is exceeded and off when disabled. The analog data output interfaces with data acquisition systems that accept a 4.20 mA input signal.
