Introduction

1.1 Product Description

The Model 07-479 Dental kVp Meter is designed to measure the effective peak potential applied to dental type x-ray tubes. The measurement is made without direct connection to the x-ray unit being tested. The kVp Meter is a battery powered, self-contained instrument designed for portable use.

The kVp meter uses two differentially filtered detectors whose ratio of integrated outputs is calibrated over the range of 45 to 90 kVp. Measurement results are presented on an easy to read 3 ½ digit liquid Crystal Display. Status is indicated by decimal point positioning on the readout. Low battery condition is indicated by LO BAT displayed on the readout.

1.2 Specifications

Distance Dependence Negligible for SSD of 20 cm or greater

Angle Dependence Negligible for 10 degrees or less

Position Dependence Negligible for misalignment of 5 cm or less at 30 cm

Calibration Period One year

Minimum Requirements 5 mAs @ 45 kVp (20 cm)

0.03 mAs @ 90 kVp (20 cm)

Power Requirements 9 V Alkaline Battery, MN1604A or equivalent

Display 3 ½ Digit LCD

Low Battery Indication: LO BAT High kV Indication: Left blinking decimal Lo kV Indication: Middle blinking decimal High Intensity Indication: Right blinking decimal and non-zero display Low mAs Indication: Right blinking decimal and zero display

LED Indicator Auto Reset, new exposure detected, and last reading cleared.

Controls Front Panel: Power switch and phase selection switch.

Output Connector BNC Connector on rear panel for waveform output.

1.3 Receiving Inspection

Upon receipt of the kVp meter:

1. Inspect the carton and its contents for damage. If damage is evident, file a claim with the carrier and notify Fluke Biomedical, Radiation Management Services at 440.248.9300.

2. Remove the unit from the packing material. Verify that the following items have been received and are in good condition:

• (1) Model 07-479 Dental kVp Meter, P/N 164000

• (1) MN1604A (or equivalent) 9 V Alkaline Battery, P/N 16-29

• (1) Model 07-479 Operator's Manual, P/N 165001

If any of the listed items are missing or damaged, notify Fluke Biomedical.

1.4 Storage

If necessary, the kVp meter may be stored in an area free of corrosive materials, temperature and humidity fluctuations, vibration, and shock. In addition, the storage area should satisfy the environmental specifications of the unit.
