NCV-1 Voltage Test camera identifies power line problems. It helps companies improve their overall efficiency by helping reduce or eliminate costly electric bills. Ncv-1 is a two-position, in-line voltage-inspector that stands on top of the wall. This equipment can be mounted on a surface, in a closet, or anywhere you need a visual reference. NCV-1 uses the photo-receiver, which can be used with an optional VGA or composite video input. The two cameras inside the unit are designed for high reliability and ease of installation.
Ncv-1 has an integrated digital control display that allows users to view a full range of the work area. The user can switch between cameras by changing the angle on the seat. High intensity illumination and bright green led for each VGA-out (VCC) helps the operator see the area without being blinded by overhead lights. The two-position, high-bright green led for each VCC helps the operator see the area without being blinded by overhead lights. NCV-1 Voltage Tester has two modes:
o On-site: This mode provides a visual reference point for testing electrical connections and powerline installation. If a problem exists, this mode will automatically detect the problem and recover power. On-site testing is highly accurate. It does not require any VCC to activate the tester. This is a good choice for monitoring existing powerlines in sensitive areas such as powerlines. If a problem exists, this mode will automatically detect the problem and recover power.
o Non-contact: Non-contact voltage tester supplies power through standard CTS/TCS and does not require any VCC to activate. This is an ideal choice for testing items with low or no drop protection. The low-drop protection of the NCV-1 allows testing regardless of the direction of the powerline.
o Standard voltage in cables, cord assemblies, circuit breakers and lighting fixtures: When testing standard voltage in cables or cords, the bright green led indicator provides a visual reference point. The accuracy of the test is guaranteed. This is also a good choice for testing lighting fixtures and outlets in sensitive areas such as powerlines. The high-bright green led indicator enables an operator to monitor the voltage drop across the circuit at all times without having to manually examine the instrument.
o High intensity: High intensity (HIG) fluorescent and photoresistor based testing offers high accuracy and reliability. The high-intensity is used to identify problematic areas of a wiring system. Photoresistor based products offer high data rate capability and a consistent and repeatable performance level. In addition to the high intensity sensitivity, these products provide non-contact and contact modes. NCV-1 includes HIG photoresistor based testers as well as some NCV-1 accessories.
o Self-contained solution: The NCV-1 tester provides non-contact and contact detection. The self-contained solution includes a desktop or stand-alone unit and an optional accessory plug. The accessories plug connects the NCV-1 to a power supply that includes a fuse. The accessory plug also connects the NCV-1 to an optional wiring accessory called the wire crimper.
o Flexible options: There are a number of optional features available with the NCV-1 testing tool. These options include data recovery, fault indication, multiple mode operation, and battery backup. The data recovery allows the user to recover lost or improperly terminated data. Multiple mode operation allows the user to select different tests for a cable from a variety of possible sources.
o Backup power: The backup power is useful when the unit is used and the main source of power is down. The backup power is provided when the negative charge on a cable is applied to a battery. The cable assembly is then connected to the computer and the electrical output is routed to an electric motor. This provides an option for testing multiple cables at one time.
When testing components using a NCV-1 Voltage Tester, it is important to use the correct polarity of connection for the test cable. If the cable is the wrong polarity, the machine may generate a false result. Also, excessive or unusually high voltage levels can damage sensitive electrical components. When the voltage is low, the device may not work or may generate an error code that needs to be investigated.
Test your NCVt-1 Voltage Tester with different power sources to see which one works the best. Be sure to disconnect all power connections before attempting a voltage tester test. Before testing, be sure to change out the batteries in the tester and store the units in a safe location. Read the user's manual for proper maintenance of the unit.
