To avoid injury, read and understand the associated documentation for MZ4 HD-UV Gun
Tube Inspection System component prior to attempting operation. Direct any questions
about equipment operation to the InterTest Customer Service and Support Group at 908-

DANGER, Explosion Hazard: Do not use this system in explosive environments. The
controller requires adequate ventilation to prevent overheating. Do not cover or drape the
controller. To ensure adequate airflow, provide a three-inch (7.6 cm) clearance between the
controller chassis vents and any solid objects.
IMPORTANT: Use caution when replacing lamps (WHITE LIGHT LAMPS ONLY) as they may
be hot. Only replacement lamps from iShot Imaging should be used. Refer to the Changing
a Lamp Section on Page 27.
IMPORTANT: Proper use of this product requires a protective earth ground path at the AC
power source. Using a two-conductor extension cord or any other device that
compromises this ground path is in violation of safe operating guidelines.
The unit should never come in direct contact with any voltage or current source. Damage
to the equipment and/or electrical shock to the operator may result.
The unit is equipped with a power supply mounted in the back of the equipment. It accepts
a 3-wire grounding type plug only. It is necessary that the equipment be grounded. The
plug will only fit into a grounding-type power outlet. This is a feature for the user’s safety.
Never use an adaptor to bypass this very important safety feature. If you cannot insert the
plug into the wall outlet, contact an electrician to replace what may be an obsolete wall
outlet. Under no circumstances should the user attempt to defeat the purpose of the
grounding-type plug.
Never attempt to modify the power cord. Do not insert or unplug the power plug with wet
hands. This could result in an electrical shock. When unplugging the power plug, always
grasp its plug portion. Never pull on the power cord directly. Pulling on the power cord
may expose or snap the internal wires, which would weaken or damage the power cord
and result in an electrical shock.
Do not place anything on top of the power cord. Never locate the equipment where people
will walk on the power cord or where heavy items may move over it. Never stretch or
excessively bend the power cord. Always insert the power cord’s plug completely into the
socket. Failure to do so could result in a fire or an electrical shock.
Never use power cords other than the power cords that were provided. Using improper
power cords could result in a fire or an electrical shock.
For safety reasons, the use of an extension cord is not recommended. If an extension cord
must be used with the equipment, ensure that the total amperage rating of the extension
cord is equal to or greater than 15 amperes. If an extension cord must be used, never allow
other devices to share the extension cord.
IMPORTANT: Never use the equipment in a wet or overly damp location. Exposing the
equipment to water or other liquids could result in a fire or an electrical shock.
IMPORTANT: The MZ4 HD-UV Gun Tube Inspection System is to be used for inspecting
gun tubes, Tank gun tube, mortar tube, ship gun tube, turbine rotor bores, generator rotor
