Transforming Technologies CM330 — Spartan Max Constant Monitor, Single Wire Wrist Strap & ESD Mat
The Transforming Technologies CM330 Spartan Max (SKU: CM330) is a continuous ESD constant monitor that simultaneously monitors one single-wire wrist strap and one ESD work surface (mat). Enclosed in a durable metal case with built-in mounting brackets for under-table installation, the CM330 eliminates time-consuming periodic wrist strap testing and removes the risk of wrist strap failure going undetected during a shift. Factory calibrated — no annual recalibration required. Meets or exceeds ANSI ESD S20.20 recommendations.

Frequently Asked Questions
What does the CM330 monitor?
The CM330 simultaneously monitors one single-wire wrist strap and one ESD work surface (mat). It uses capacitance technology — sending a signal through the wrist strap to detect the capacitance of the person and ground. If either the wrist strap connection or the mat ground connection fails, the monitor triggers audible and visual alarms.
Does the CM330 require annual calibration?
No — the CM330 is factory calibrated and designed to be adjustment-free. Annual recalibration is not required. If your quality program requires functional verification, the CM330PV verification tool is available to confirm the monitor is operating correctly without requiring recalibration.
What is the relay terminal used for?
The built-in relay terminal activates when the monitor detects a failure (wrist strap, mat, or ground). It can be wired to external devices such as light towers, buzzers, electronic door locks, or power switches to automate the response to an ESD failure — for example, preventing access to a static-sensitive area or cutting power to equipment until the fault is resolved.
What is the operator presence sensor?
The CM330 includes an infrared operator presence sensor that detects when a person is at the workstation. If a person is sensed but is not connected to the monitor via a wrist strap, the alarm triggers. This prevents the scenario where an operator is working at an ESD-protected station without being grounded.
Is the CM330 compatible with my existing wrist straps and ESD mats?
The CM330 is compatible with standard single-wire wrist straps and most ESD mats. It is not compatible with dual-wire wrist straps. Contact MTE Solutions to confirm compatibility with your specific wrist strap and mat before ordering.
