Continuous Wrist Strap Monitors

Single Wire Continuous Monitors

Single wire continuous monitors offer the most cost-effective means for continuously testing the connection integrity of the entire ground loop including the person, the wrist band and the coil cord. By using new impedance sensing technology, adjustments and false alarms are virtually eliminated. This system is fully automatic and activates when a wrist strap is plugged into the unit. It provides a green light for safe condition and a red light and tone for unsafe condition. Units are powered and grounded by an AC adapter. Compatible with most standard wrist straps.

Per ESD Handbook TR 20.20 paragraph 5.3.2.4.4 "Typical test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, then continuous monitoring should be considered or even required."

Test Module -- Since these monitors use solid state circuitry, adjustments or calibration is not required. However, many quality programs require that proper operation of constant monitors be verified. The TMTOOL unit simulates a correctly functioning person and wrist strap (Accept) and an open circuit (Reject.) If your quality program requires testing of constant monitors, be sure to request information on the TMTOOL in addition to the Continuous Monitors.
