Page 5: Introduction
This manual describes the proper care and use of the C9970 Voltage Detector and its accessories. Read this manual completely before using the Voltage Detector. -
Page 6: Safety Information
C9970 Voltage Detector Users Guide Safety Information The following IEC symbols are used either on the Voltage Detector or in this manual: Warning: Risk of personal injury. See the manual for details. Caution: Risk of damage or destruction to equipment or software. -
Page 7: Care And Maintenance
Care and Maintenance Do not use the Product around explosive gas, vapor, or in damp or wet environments. Do not directly contact voltages greater than 1000 VAC. If the voltage to be measured is unknown, do not directly contact the voltage. -
Page 8: Environment
Do not store the Voltage Detector near strong magnets. Battery Replacement When replacing batteries, work in a dry place. Always replace the battery with a 9 V zinc-carbon battery. Fluke Networks recommends a Rayovac® 9 V battery, Model D1604. Caution Some imported 9 V batteries are slightly oversized. -
Page 9: Safety Gloves
Safety Gloves To replace the battery, do the following: Open the Voltage Detector body by unscrewing the handle in a counter- clockwise direction and sliding it back from the front assembly. Do not attempt to loosen the check contact or the ground terminal. Gently slide the battery out of the metal shield, attach a new battery, and slide it back into the metal shield. -
Page 10: Physical Description
C9970 Voltage Detector Users Guide Physical Description The Voltage Detector, shown in Figure 1, is a yellow, plastic, two-piece, unit that weighs approximately one pound. The front housing includes the carbide probe tip and two LEDs (one green and one red) along with a check contact and a ground terminal. These and the battery are attached to the front housing. -

Page 15: Operation
Operation Operation To use the Voltage Detector, do the following: Before using the Voltage Detector, always perform a self check (see “Self Check” on page 8). Remove the black conductive end cap from the probe tip. Be careful not to unscrew the front and rear housing while removing the cap. Hold the Voltage Detector as shown in Figure 4. -
Page 16: Ac Hazardous Voltage Testing
C9970 Voltage Detector Users Guide AC Hazardous Voltage Testing No grounding is required except when testing aloft near power transmission lines (see “Aerial Testing” on page 14). Warning For AC measurements, do not make contact between the metal probe tip and exposed bare wire. -
Page 17: Dc Hazardous Voltage Testing
Operation DC Hazardous Voltage Testing The Voltage Detector indicates the presence of DC voltages between 6 VDC and 1500 VDC. When testing DC voltages, a connection must be established between the ground terminal of the Voltage Detector (see Figure 1) and a known earth ground. -
Page 18: Aerial Testing
C9970 Voltage Detector Users Guide Still holding the switch down, remove the Voltage Detector from the object and observe the LEDs: The green LED means a safe condition. The red flashing LED indicates hazardous voltages. If a hazardous voltage is present, move away from the object and refer to your company’s safety procedures. -
Page 19: Ground Level
Applications Ground Level Mobile homes, trailers, metal sheath buildings, ground rods and electrical machinery all present potential electrical hazards and always require testing. Before starting any work operation, test the skin and frame (or both frames in the case of double wide mobile homes). In some cases, such as when driving a ground rod, you might wear rubber gloves during the work operation. -

Also,... -
Page 21: Ungrounded Insulated Conductors
Applications insulation on the bond may overheat and smoke which should alert you to descend the pole. Using insulating gloves, attach the bond in the following manner: Attach the small clip of the temporary bond to the cable suspension strand in such a manner that it will not be in the way of work operations. Attach the large clip of the bond wire to the fixture, conduit, or bare vertical ground wire. -
