Some of the details of components illustrated in this manual may differ from the
components installed on your instrument. However, the operating principles remain
the same.
Instrument Compatibility
The Vanta GX analyzer is primarily a self-contained unit. However, it does have USB
ports that enable you to connect compatible peripherals. It also derives its required
DC input power from a standard accessory AC adapter.
Always use accessories and peripherals that meet Evident specifications. Using
incompatible accessories or peripherals could cause equipment malfunction and/or
damage, or human injury.
Repair and Modification
The Vanta GX analyzer does not contain any user-serviceable parts, apart from one
exception: the measurement window. If the measurement window is damaged, the
window assembly should be replaced as soon as possible. See “Maintenance” on
page 59 for the window-assembly removal and reinstallation instructions.
Opening of the instrument housings (lid, base, and control enclosure, including the
touch-screen display) by anyone other than an Evident-trained service person will
void the warranty.

Radiation Safety Warnings
• The Vanta GX analyzer is a closed-beam instrument with respect to ionizing
radiation. Therefore, when properly using the analyzer, the operator and near-by
associates will not encounter radiation levels greater than those allowed by local
regulations.
• Do not attempt to bypass or defeat the safety interlock system.
See “Safety Information” on page 37 for more information about safety.
Mechanical Safety Warnings
The Vanta GX analyzer is comprised of three major mechanical assemblies:
• A shielded lid with a bismuth-acrylic viewing window.
• A shielded main body with a test chamber, XRF measurement window, and
failsafe LED array.
• A control enclosure that includes:
— An I/O display with touch-screen panel
—Apowerswitch
— Navigation keys
—USBport
— A mechanical lid latch
The lid and main body are connected by integral hinges assisted by two dampening
closures. The control enclosure is permanently fixed to the front of the shielded body.
