The Resistance Ranger Constant Monitors Series are a cost effective and accurate system to ensure that an ESD workstation station is grounded. The system continually monitors the resistance levels of the grounding products and alarms if they fail. The system uses superior dual wire wrist straps that provide two paths-to-ground to ensure ESD protection. The Rangers can also monitor the resistance levels of ESD worksurfaces and grounded tools and alarm if there is an issue. All three models use an ultra-low voltage sensing current and are designed for use in the most sensitive environments and processes.
The Ranger Series is factory calibrated and does not require annual recalibration. It is recommended to verify the monitors are in proper working order with the CM2015PV periodic verification unit.
