Each Fluke Networks product is warranted to be free from defects in material and
workmanship under normal use and service. The warranty period for the mainframe is one
year and begins on the date of purchase. Parts, accessories, product repairs and services are
warranted for 90 days, unless otherwise stated. Ni-Cad, Ni-MH and Li-Ion batteries, cables
or other peripherals are all considered parts or accessories. The warranty extends only to
the original buyer or end user customer of a Fluke Networks authorized reseller, and does
not apply to any product which, in Fluke Networks’ opinion, has been misused, abused,
altered, neglected, contaminated, or damaged by accident or abnormal conditions of
operation or handling. Fluke Networks warrants that software will operate substantially in
accordance with its functional specifications for 90 days and that it has been properly
recorded on non-defective media. Fluke Networks does not warrant that software will be
error free or operate without interruption.
Fluke Networks authorized resellers shall extend this warranty on new and unused products
to end-user customers only but have no authority to extend a greater or different warranty
on behalf of Fluke Networks. Warranty support is available only if product is purchased
through a Fluke Networks authorized sales outlet or Buyer has paid the applicable
international price. Fluke Networks reserves the right to invoice Buyer for importation costs
of repair/replacement parts when product purchased in one country is submitted for repair
in another country.
Fluke Networks warranty obligation is limited, at Fluke Networks option, to refund of the
purchase price, free of charge repair, or replacement of a defective product which is
returned to a Fluke Networks authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke Networks authorized service center
to obtain return authorization information, then send the product to that service center,
with a description of the difficulty, postage and insurance prepaid (FOB destination). Fluke
Networks assumes no risk for damage in transit. Following warranty repair, the product
will be returned to Buyer, transportation prepaid (FOB destination). If Fluke Networks
determines that failure was caused by neglect, misuse, contamination, alteration, accident
or abnormal condition of operation or handling, or normal wear and tear of mechanical
components, Fluke Networks will provide an estimate of repair costs and obtain
authorization before commencing the work. Following repair, the product will be returned
to the Buyer transportation prepaid and the Buyer will be billed for the repair and return

Since some countries or states do not allow limitation of the term of an implied warranty,
or exclusion or limitation of incidental or consequential damages, the limitations and
exclusions of this warranty may not apply to every buyer. If any provision of this Warranty

C9970 Voltage Detector
Introduction
The C9970 Voltage Detector is a high-voltage probe used for detecting hazardous
voltage on conductive objects such as power ground wires, street light fixtures,
mobile homes, metal frameworks, metal conduit, pedestals, newly-driven ground
rods, homes covered with metallic siding, and electrical machinery.
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.
Registration

Warning: Risk of personal injury. See the manual for details.
Caution: Risk of damage or destruction to equipment or software.
See the manual for details.
Warning: Risk of electric shock.
Earth ground
Do not put products containing circuit boards into the garbage.
Dispose of circuits boards in accordance with local regulations.
WXWarning
To avoid possible electric shock or personal injury, follow these
guidelines:
•
Only qualified personnel who have been trained and are knowledgeable
about the dangers associated with hazardous voltages should use this
product.
•
Be sure to know and follow your company’s procedures for every
application. Any conflict between the procedures specified in this manual
and those of your company must be resolved before using the Voltage
Detector.
•
Do not use the Voltage Detector if it is damaged.
•
Before you use the Voltage Detector, inspect the case. Look for cracks or
missing plastic. Pay particular attention to the insulation surrounding the
connectors.
•
Do not use if wet.
•
Inspect the Voltage Detector for damaged insulation or exposed metal.
•
Do not use the Voltage Detector if it operates abnormally. Protection may
be impaired. When in doubt, have the Voltage Detector serviced.
•
Do not operate the Voltage Detector around explosive gas, vapor, or dust.
•
Do not apply more than the rated voltage, as marked on the Voltage
Detector, between terminals or between any terminal and earth ground.
•
Before use, verify the Voltage Detectors operation by measuring a known
voltage.
•
When servicing the Voltage Detector, use only specified replacement parts.
•
Use caution when working above 30 V ac rms, 42 V peak, or 60 V dc. Such
voltages pose a shock hazard.

Care and Maintenance
•
Do not use in excess of the voltage specified in this manual.
•
When using probes, keep your fingers behind the finger guards on the
probes.
•
Remove any voltages from the Voltage Detector before accessing the
battery.
•
Do not operate the Voltage Detector with portions of the case removed or
loosened.
•
To avoid false indications, which could lead to possible electric shock or
personal injury, replace the batteries as recommended. See “Battery
Replacement” on page 4 for additional information.
•
Use only type 9 V batteries, properly installed in the Voltage Detector case,
to power the Voltage Detector.
WCaution
To avoid possible damage to the Voltage Detector or to the
equipment under test, use the proper terminals and function for your
measurements.
Care and Maintenance
Any Voltage Detector with confirmed or suspected damage to the plastic housing
(deep scratches, cracks, holes, etc.) or internal circuitry should never be used.
Mechanical Shock
Do not drop the Voltage Detector or subject it to severe mechanical stress which
may damage the protective insulation or internal circuitry. The Voltage Detector
should be tested and repaired if it appears to be damaged or fails to meet the tests
described in “Periodic Performance Tests” on page 8.
Environment
Do not expose the Voltage Detector to extreme temperatures (below -40 °C or
above +60 °C) or chemicals that may soften, crack, or otherwise damage the plastic
housing.
