The CM2015PV is the Periodic Verification Tool. The CM2015PV is designed to verify calibration for the CM2800, CM 2815 and the CM2800 Series Dual Wire Constant Monitors. The CM Series Constant Monitors are factory calibrated and do not need on site calibration. However, periodically the CM2015PV unit can be used to verify that the ground monitors are in proper working order. |
