Powering Off the Tester

The NetTek YBT1 has separate, interrelated, standby and power off
functions.

Suspend Mode

Use Suspend mode to place the NetTek YBT1 in a suspended
(standby/sleep) state. This is the typical power down mode that
allows the NetTek YBT1 software to remain in volatile memory. If
the NetTek YBT1 remains in Suspend mode for an extended time
(approximately two hours), it will automatically enter Shutdown
mode.

Preventing Personal Injury from the Effects of Lightning

WARNING. To prevent personal injury from the effects of lightning,
exercise the following precautions when using this product.

Before connecting this product to any source

H Be sure there is no lightning in your vicinity.

H Check your local weather forecast for the possibility of

thunderstorms or lightning.

H If weather conditions could allow thunderstorms or lightning to

develop, be sure to visually check the sky and weather conditions

in your area frequently.

H If you hear thunder or see lightning, do not connect this product

to any source that may be exposed to the effects of lightning.

H Use your own good judgement and common sense. You must

protect yourself from the effects of lightning.

H You must assume that hazardous voltages will be present on

exposed surfaces of this product if it is connected to a source

exposed to lightning. The insulation of this product will not

protect you from these hazardous voltages.

Do not connect this product to any source that might be subject to the
effects of lightning

If thunderstorms or lightning are in your vicinity:

H When weather conditions that could lead to lightning activity

exist in your area, you could be at risk of a lightning strike

before the cloud is close enough for you to hear thunder or see

lightning.

1- 12

NetTek YBT1 T1 Circuit Tester User Manual

Getting Started

H When lightning strikes a structure or facility, current travels

through the rebar, concrete, pipes, cables, vent stacks, and
electrical system.

H Lightning can induce electric and magnetic fields into structures

and portions of wiring. The length of a conductor affected by the
magnetic field of a lightning strike may exceed two miles.

Be alert and aware of the effects of l ightning

H When lightning strikes a conductor, which in turn introduces

current into an area some distance from the ground strike point,
equipment can be damaged and personnel injured if they
become an indirect path in the completion of the ground circuit.

H Conductors such as the braided shields of cables or unshielded

wire, will have significant transient currents flowing in them in
regions exposed to the electric field effect of lightning.

H Induced voltages may cause breakdown of insulation in wiring at

connectors and in electrical components, or breakdown of air.
