The CM420 is a single wire ESD constant monitor for two ESD wrist straps and one ESD worksurface ground.

The CM420 is a single wire ESD constant monitor for two ESD wrist straps and one ESD worksurface continuously checks two operators wrist straps and a workstation ground and alarms if there is a fault. Continuously verifying the integrity of the ground system is critical to an effective ESD protection program and eliminates the time-consuming task of testing wrist straps before each shift. The systems are compatible with most single wire wrist straps. This is the simplest, and most cost-effective way to ensure a wrist strap is continually working. An audible alarm and light will signal a failure.

  • Monitors Two Operators and One Workstation Mat
  • Easy To Use: Simply Plug In Wrist Strap
  • Audible and Visual Alarms
  • Factory Calibrated – Does Not Require Recalibration

 Calibration for ESD constant monitor

The CM420 constant monitors are factory calibrated and are designed to be adjustment free. Annual calibration is not necessary. If a quality program requires testing, verification tools that simulate a functional and non-functional wrist strap are available to verify that the monitor is functional. It is recommended to verify proper working order with the CM420PV  periodic verification unit at least once per year.

If a quality program requires testing, verification tools that simulate a functional and non-functional wrist strap are available to verify that the monitor is functional. It is recommended to verify proper working order with the CM410PV  periodic verification unit at least once per year.

The (CM410PV /CM420PV ) constant monitor verification units are factory calibrated and do not require annual re-calibration. Calibration can be verified by comparing them to 3% tolerance resistors although this procedure is unnecessary and is not recommended. If the CM410PV / CM420PV  are unable to operate, contact Transforming Technologies for more information.
