Ohm-Stat CM-1701 Guardian Plus Constant Monitor — Continuous ESD Ground Monitoring for 1 Operator (Single-Wire Wrist Strap) + 1 Worksurface Mat, LED + Audible Alarm, NIST Calibration Included
1 Operator Monitors Wrist Strap + Mat Single-Wire Capacitance Wrist Straps Blinking Red LED + Piezo Buzzer NIST Calibration Included 110V AC ESD Workstation Monitor
Overview

The Ohm-Stat CM-1701 Guardian Plus is a constant ESD monitor designed for a single workstation where you want continuous verification of (1) the operator’s wrist strap ground path and (2) the ESD worksurface (table mat) ground path. If either path-to-ground is broken or drifts beyond preset limits, the device alerts immediately via a blinking red LED and piezo buzzer.

For electronics work in cleanrooms or controlled environments (and for non-cleanroom electronics assembly and repair), continuous monitoring helps reduce the risk of ESD events that can cause catastrophic failures or latent defects. SOSCleanroom supports these programs with trusted ESD brands, clear product data, and easy replenishment options like Auto-Ship.

Why this monitor matters in ESD-controlled work
  • Instant feedback: identifies loss-of-ground conditions as they occur—not after product has been handled.
  • Monitors the two most critical paths: operator wrist strap and worksurface mat grounding at the point of work.
  • Common point grounding behavior: published design notes indicate the operator/mat remain connected to ground even with the switch off.
  • Supports audit readiness: NIST calibration inclusion and defined alarm behavior support stronger documentation and training.
Typical applications
  • Electronics assembly, test, inspection, rework, and repair benches (ESD Protected Areas)
  • Cleanrooms handling electronics (static risk can increase when humidity is controlled and synthetics are common)
  • Medical device electronics, sensors, optics subassemblies, and calibration labs
  • Any workstation that uses an ESD mat and requires continuous assurance of grounding performance

ESD Education Wrist Strap + Mat Grounding Continuous Monitoring Electronics in Cleanrooms
ESD is a yield risk and a reliability risk

ESD events can damage sensitive components instantly, or create latent defects that pass functional testing and fail later in the field. Cleanrooms and controlled environments often use synthetic garments, plastics, and airflow controls that can increase static generation. Low humidity conditions can further increase static buildup risk, which is why electronics-focused cleanrooms frequently require an explicit ESD Control Program Plan in addition to contamination controls.

Two fundamentals at the workstation: ground the person and ground the surface

At a seated workstation, personnel grounding is typically achieved through a wrist strap system connected to a selected grounding / equipotential bonding system. The ESD work surface (table mat) must also maintain a reliable path-to-ground so charges can dissipate predictably during handling.

Practical takeaway

If either path is compromised (operator strap/cord, ground point, mat ground lead), your workstation becomes an uncontrolled risk zone.

Why continuous monitoring exists

Point-in-time wrist strap tests are valuable, but they cannot detect failures that occur mid-shift (cord fatigue, loose snaps, intermittent docking contact). Continuous monitors are designed to provide immediate status feedback of the path-to-ground, helping teams catch failures before product is handled.

  • Faster response: alarm triggers at the point of work (where risk happens).
  • Better behavior reinforcement: operators see the outcome of correct/incorrect docking immediately.
  • Cleaner documentation story: many programs treat continuous monitoring as a core control for higher-risk products and processes.
Where CM-1701 fits: one operator + one mat, always watched

The Ohm-Stat CM-1701 Guardian Plus is designed for workstations that need both operator and worksurface assurance. It monitors the operator’s single-wire wrist strap ground path and also monitors the ESD worksurface (table mat) ground path. If either path breaks, the monitor alerts using a blinking red LED and piezo buzzer. Published information also notes a common-point grounding behavior where the operator/mat remain connected to ground even when the unit is switched off.

Setpoint control (why it matters)

Operator impedance and mat resistance setpoints are described as adjustable. This supports better alignment to your workstation configuration and your ESD Control Program Plan, especially when operators vary and mat types differ.

Implementation checklist (simple and effective)
  1. Verify the ground point first: use an outlet/ground checker before you rely on any receptacle-grounded system.
  2. Define your common point ground: avoid daisy-chaining grounds between benches.
  3. Standardize straps and cords: lock down approved wrist strap and cord models to reduce process drift.
  4. Train response behavior: what the operator does immediately when alarms occur (stop work, re-dock, replace cord/strap, notify lead).
Why buy ESD controls from SOSCleanroom
  • One-cart workstation builds: monitors, wrist straps, cords, heel grounders, and ground-check tools in one procurement flow.
  • Operational continuity: Auto-Ship options help keep critical ESD consumables from becoming production blockers.
  • Training-friendly content: Technical Vault writeups support consistent onboarding and refreshers for operators and supervisors.

Documentation note

Continuous monitors support—but do not replace—your ESD Control Program Plan. Maintain controlled configurations, verification routines, and training records aligned to your program requirements.
