Introduction

Introduction

The Fluke Biomedical TNT 12000 X-ray Test Tools (the TNT 12000) are used to calibrate and service diagnostic X-ray imaging systems.

The TNT 12000 X-ray Test Tools has these parts:

•TNT 12000WD X-ray Detector option (the X-ray Detector). The X-ray Detector contains an array of solid-state sensors and filters that measure kV, Dose, Half-Value Layer (HVL), and exposure time.

•TNT 12000 DoseMate option (the Dosimeter Detector). With its related ion chambers, the Dosimeter Detector measures dose and rate on all X-ray modalities: radiographic, mammographic, dental, cine, fluoroscopic, and CT.

•TNT 12000 mAs option (the mAs Detector) to measure X-ray tube current over time. Use the mAs Detector on radiographic (or Dental or Mammography) and fluoroscopic X-ray imaging modalities. The mAs option is installed in the X-ray or Dosimeter Detectors.

•TNT 12000 Display (the Display). The Display contains a 320 x 240 color LCD, four navigation buttons, an ENTER button, and a power button. The display controls testsystem functions and shows all system measurements.

•TNT 12000/DoseMate/mAs CD that contains an Excel Add-in to control the test system and import all measurements.

•AC Power Adapter used to charge the rechargeable batteries in the X-ray Detector, Dosimeter Detector, mAs Detector, and the Display.

The TNT 12000 options communicate between the detectors and the display or computer through a wireless (ZigBee) or wired (USB) connection.

Unpacking and Inspection

The TNT 12000 is shipped in a container designed to prevent damage during shipment. Examine the components for damage, and immediately report any damage to the shipper. Keep the damaged shipping container and packing material for inspection by the carrier.

Note

The shipping container contains foam inserts to prevent damage during shipment. Keep these and the container for future shipment.

When you unpack the TNT 12000, compare the parts to the packing list. If you ordered the mAs option, make sure it is installed in a Detector by looking for an mAs input jack on a Detector. See the Familiarization section later in this chapter. Report any shortage to the place of purchase.

Storage

To store the TNT 12000, put it in its carrying case. Keep it in an environment free of corrosive material and within the storage temperature and operating humidity ranges shown in the specifications. Also prevent vibration and shock to the system.

How to Charge the Battery

How to Charge the Battery

Charging the internal batteries of the detectors and display from mains power can be done in three different configurations as shown in Figure 1-1.

WCaution

To prevent damage to the TNT 12000, do not leave batteries unused for an extended period of time. When a battery has not been used for six months, check the charge status and charge if necessary.

Figure 1-1. Charging Methods

To charge a Detector or the Display directly from mains power, connect the ac-power adapter directly to the ac adapter connector on a Detector or the Display. To charge a Detector and the Display simultaneously, connect the ac adapter to the ac adapter connection on the Display and then, using the Mini-B to Type-A USB cable, connect the Detector to the Display.

Note

See the markings on the ends of the cable to identify the Mini-A and Mini-B ends.

A Detector or Display battery can also be charged through a USB connector on a PC. Connect the Display or Detector to a PC USB port using the Mini-A to Type-A USB cable.

Both Detectors and the Display have a battery-status indicator to indicate the condition of the internal battery. The indicator is a tri-color LED that shows the level of charge on the internal battery. Table 1-5 explains the battery-status indicator levels.
