Brand: SCS
Model : 770716, 770717, 770719, 770009
Description:
The SCS 770716 Static Sensor indicates surface voltage and polarity on objects. The meter has a measurement range of 0 to ±19.99 kV at a distance of 1 inch and a measurement accuracy of ±5%. It utilizes a chopper-stablized sensor for use in both normal and ionized environments. The meter’s enclosure is dissipative and features a 7 mm snap and ground cord for bonding to equipment ground. A rotary zero knob sets the zero-reference point with finely tuned precision, and a Hold button allows the user to “freeze” a displayed measurement for evaluation. A LED range indicator assists with placing the meter at the correct distance from the object being measured.
The SCS 770717 Air Ionizer Test Kit includes and utilizes the 770716 Static Sensor to measure the offset voltage (balance) and charge decay of ionization equipment. The Air Ionizer Test Kit also includes a charger used to place a ±1000V charge on the conductive plate, making it possible to also measure the discharge times of air ionization equipment per ANSI/ ESD SP3.3 Periodic Verification of Air Ionizers. Although not as accurate, the SCS Air Ionizer Test Kit is designed to make measurements that correspond to those made by using a charged plate monitor and ANSI/ESD STM3.1. The Air Ionizer Test Kit provides convenience and portability to test per ANSI/ESD SP3.3 Periodic Verification of Air Ionizers or Compliance Verification ESD TR53. SCS recommends using the 770004 or 770005 Charged Plate Analyzer if precise measurements are required. All Static Sensors and Air Ionizer Test Kits are calibrated to NIST standards and include a certificate. “When any object becomes electrostatically charged, there is an electrostatic field associated with that charge. If an ESDS (ESD sensitive) device is placed in that electrostatic field, a voltage may be induced on the device. If the device is then momentarily grounded, a transfer of charge from the device occurs as a CDM (Charged Device Model) event. If the device is removed from the region of the electrostatic field and grounded again, a second CDM event will occur as charge (of opposite polarity from the first event) is transferred from the device.” (Handbook ESD TR20.20 section 2.7.5 Field Induced Discharges)
