Introduction
This chapter gives instructions on how to connect, setup, and use the TNT 12000 to
calibrate and service X-ray equipment. It is assumed the reader already read Chapter 1
and understands the Test Tool components.
Safety Information
In this manual, a Warning identifies conditions and actions that pose hazards to the user.
A Caution identifies conditions and actions that may damage the TNT 12000 or the
equipment under test.
XW Warnings
To prevent electric shock:
Use the TNT 12000 as specified in this manual or the protection
provided might be impaired .
Inspect the test leads for damaged insulation or exposed metal.
Check the test leads for continuity. Replace damaged test leads
before using the TNT 12000.
Turn the X-ray generator power off before connecting or
disconnecting the TNT 12000.
W Caution
To prevent damage to the TNT 12000, Do not apply more than
500 V, between the input and earth ground.
How to Set Up the System
The Display controls the detectors and must be set to communicate with a Detector
before you can make a measurement. When connected, all measured values are shown in
the Display.
The subsequent setup step is to prepare the Detector for a measurement. For X-ray
Detector measurements, put the Detector in the X-ray beam. For the Dosimeter, an ion
chamber is connected to the Dosimeter and put in the X-ray beam.
When an mAs Detector is installed in the X-ray Detector or Dosimeter Detector, you
connect the X-ray detector to the X-ray generator. You do this with test leads connected
to an mAs test point or a non-invasive mAs clamp.
Display to Detector Communications
Communication between the Display and a Detector is through a wireless (ZigBee) or
wired (USB) connection. All Test Tool components communicate in these two ways.
The X-ray Detector and Dosimeter Detector have a communication status indicator to
indicate the condition of communications to the Display. See Table 2-1.
