MODEL MA0396 DUAL-RANGE MAS METER

Dual-Range mAs Meter Model MA0396
The Digital mAs Meter is an accurate, low-cost instrument that allows service personnel and biomedical engineers to check and adjust the mA settings of x-ray generators.  This easy-to-use device is calibrated directly in mAs, thereby avoiding the calculations required with more complicated (and expensive) calibration equipment.  The Dual-Range mAs Meter Gammex MA0396 is very sensitive ¨C it can measure increments of 0.1 mAs.  It has a low range of 0 to 199.9 mAs; and a high range of 0 to 1999 mAs.  This meter excels in calibrating the high-current, short-time station where a conventional mAs meter is precluded by tube ratings.  This instrument can be used (after verification of generator timing accuracy) to set all mA stations and verify that photo-timing error does not exceed the limits of good practice.  To use, simply connect the cable to the x-ray generator and make the required exposure.  The mAs reading appears instantaneously on the 4 digit LCD.   A display indicator warns of the need for battery replacement.  The small size and light weight make it convenient to carry around in a pocket or tool kit.  Note: This is an invasive test which requires connection to the generator circuit.
