USER GUIDE TB-9016 718 Static Sensor Installation, Operation and Maintenance Made in the United States of America 7. The SCS Static Sensor 718 has a Low Battery indicator. Once the battery is depleted to approximately 6.5 volts, the instrument will show BAT in the display. At this time, the Static Sensor 718 will not produce accurate results and the battery should be replaced. 8. The SCS Charger 718A also has a low battery indicator. This is an LED located at the left-hand side of the unit. When the battery voltage drops below operating level, the LED will light up. At this time, the user shouldreplace the battery. Usage of the Charger 718A under low battery conditions would lead to insufficient voltage levels being generated. Figure 1. (Left to right) SCS 718 Static Sensor and SCS 718A Air Ionizer Test Kit. Description The SCS Static Sensor 718 is a portable handheld instrument used for locating and measuring electrostatic charges. It can be used to locate ESD trouble-areas, and is a valuable tool for the ESD-control engineer. Used in conjunction with the SCS Air Ionizer Test Kit 718A (sold separately), it can be used for verification and auditing of air ionizers. The Static Sensor 718 is battery-powered Figure 2. SCS 718 and 718A Battery Replacement and has several measurement features: and Indicators. Range: measurements can be taken in a 0 to ±1.999 kV Operation of the Static Sensor 718 or 0 to ±19.99 kV range.

As the instrument gets closer to the one inch measurement distance, the bull’s-eyes begin to converge. When they converge and become one, the instrument is approximately one inch away, and the measurement can be made. For more accurate measurements, it is recommended that the user manually measure the distance between the front housing of the instrument and the object being measured.

Three digits following the decimal point indicate that the unit is in 0 to ±1.999 kV range. Two digits following the Continuous Output: an output jack is provided on decimal point indicate that the sensor is in 0 to ±19.99 kV range. To change between measurement ranges, press the RANGE/HOLD button once, momentarily. HOLD Function: in the event that the user wishes to freeze the current measurement, the HOLD function of the Static Sensor 718 may be used. Simply press the HOLD switch momentarily and the currently displayed voltage will be frozen. A HOLD notice will also be displayed to alert the user that the instrument is currently in HOLD status.

Automatic Shut-Off: the Static Sensor 718 will automatically shut-off 20 minutes after the last switch activity. This is done in order to conserve battery power. In the event that the user needs to have the unit stay ON continuously, when turning the unit on press the POWER AND RANGE switches simultaneously. This deactivates the Automatic Shut-Off feature. The BAT indicator will then flash three times to indicate that the automatic shut- off features has been disabled. The Automatic Shut-Off feature will reset itself the next time the instrument is Figure 7. Testing Ionizer Offset Balance. turned on. Testing Ionizer Discharge Time: after charging the Operation and Use of SCS Air Ionizer plate, hold the SCS Static Sensor 718 approximately one foot (30.5 cm) away from the ionizer. Monitor the display Kit 718A to see how quickly the 1.1 kV charge is dissipated to It is recommended that the user be familiar with ionizer 0.1 kV. The speed at which this occurs (the discharge test standards ANSI/ESD S3.1 and draft standard ANSI/ time) indicates how well the ionizer is operating.

Repeat this procedure for both Assembly: slide the charge plate over the Static Sensor a positively and a negatively charged plate. 718 until it stops. The charge plate slides onto the lower groove, on the sides of the Static Sensor 718. Testing ionizer offset balance: zero the charge plate by touching it with a grounded object. This can either be the finger of a grounded person or some other item which is connected to electrical ground. In either case, zeroing the charge plate should make the display on the Static Sensor 718 read zero. Hold the Static Sensor 718 approximately one foot (30.5 cm) in front of the ionizer. Monitor the display. The value displayed is the offset balance of the ionizer, which is the difference between the number of positive and negative ions being emitted. Please refer to the specific ionizer’s operating manual or Figure 6. 718 Static Sensor charging plate in use. consult with the ionizer manufacturer to determine what this offset balance should be. Charging the Plate: holding the Static Sensor 718 (with charge plate attached) in one hand, use the other hand Service/Calibration to touch the probe of the SCS Air Ionizer Test Kit 718A to the charge plate. Press either the + button (for a Service and Repair: in the event that you believe the positive voltage) or the – button (for a negative voltage), Static Sensor 718 or the SCS Air Ionizer Test Kit 718A then remove the probe from the charge plate.

If a voltage of less than ±1.1kV is displayed, check to see if the low battery indicator on the SCS Charger 718A is illuminated. If illuminated, replace the battery in the charger. If the unit continues to supply an incorrect voltage to the charge plate, please contact SCS for additional instructions. Testing ionizer discharge time: after charging the plate, hold the SCS Static Sensor 718 approximately one foot (30.5 cm) away from the ionizer.
