Works with standard one conductor wrist straps/cords
New technology -capacitance/impedance hyper technology
NIST calibration included with certificate
Visual LED, audio piezo sound
AC powered or 9 volt battery operated
Set points can be adjusted for impedance of wrist straps, capacitance of person and resistance of mats
Safe limits: .75-1.2 megohms. Inpedance can be adjusted according to weight and size of operator
Fail limits: Below .75 megohms and over 1.3 megohms
Visual alarm: red-fail, pass-green
Audio alarm: piezo buzzer
Operation: - active when switch tuned on - Inactive when power switch turned off, cord on docking snap, wrist strap on and green piezo on - Wrist straps connected to ground even if monitor turned off - Trigger impedance not changed by change of incoming voltage
Power: 110 volts or 9 volts battery with low power LED
