C9970 Voltage Detector
Users Guide
Storage Bag
The Voltage Detector storage bag holds the Voltage Detector and its
accessories. The bag’s interior is lined with plastic. The bag has a fabric strap
with a metal snap hook and a zipper closure.
Ground Cord
The Voltage Detector ground cord is used only in certain aerial applications
where the user is isolated from ground and near power transmission lines. The
cord is a
25-ft retracting cord with clamps on each end. This cord, along with the
conductive plastic end cap, eliminates induced body voltage to prevent false
hazard indications.
Test Plug
The Voltage Detector test plug is used to verify the lowest voltage (threshold
voltage) at which the Voltage Detector indicates danger. It is an AC-operated
plug that provides a suitable, current-limited, reference voltage to verify
proper operation of the Voltage Detector. It plugs into a standard, ground-
referenced, power outlet. The test plug is current-limited and may be touched
without electrical shock, even while energized. The test plug consumes less
than
30 milliwatts and may be left in an outlet indefinitely if desired.
Periodic Performance Tests
The Voltage Detector should be checked periodically to ensure that it is
working properly and that it retains its protective properties. There are two
primary tests that can be used to verify the integrity of the Voltage Detector: a
self check and a test plug threshold (sensitivity) test.
Self Check
Perform the self check before each use of the Voltage Detector to verify it is
working properly. To perform a self check, do the following:
1
Clean and dry the entire housing. Moisture, dirt, and other foreign
matter reduces the insulating properties of the plastic surface.
2
Examine the housing for cracks.
3
Grasp the handle with your bare hand. Press the trigger and observe the
green LED. If it does not illuminate or is very dim, check the internal
battery and replace if needed. If the green LED still does not illuminate,
do not use the Voltage Detector.
