BATTERY REPLACEMENT

 

 

The Model 07-453 is supplied with one 9 Volt Alkaline battery.  Replace the battery when the "Lo Bat" 
indicator shows in the display.  Any standard 9 Volt Alkaline battery can be used in the 07-453.  To meet 
the battery life specification, please use a Duracell MN1604 Battery.  This is the familiar “gold top” battery.  
To prolong battery life, turn the instrument off when not in use. 
 
To replace the battery, slide the battery compartment open on the bottom of the case.  Remove the old 
battery, and install the new battery. 
 
 

OSCILLOSCOPE OUTPUT

 

 
The 07-453 can be and usually is used without an oscilloscope, but the scope output feature enables 
technical analysis of the x-ray output.

 

 
X-ray generators often have characteristics such as gradual rise times, variations in amplitude, noise, 
capacitive filtering, and extended decay times.  Problems with x-rays can often be diagnosed by 
observing the output waveform of an x-ray with an oscilloscope.  A jack is provided on the left side of the 
07-453 case to enable a user to observe the x-ray wave form on an oscilloscope.  Plug in a standard 
2.5mm mono phone plug into the jack and attach the leads of the scope probe to the phone plug 
terminals.  Set the vertical sensitivity of the scope to about 0.2 Volt per cm.  The scope waveform will be 
an amplified version of the actual output of the x-ray detector.  

 

 
A cable with a phone plug and a BNC connector for a scope is available from Fluke Biomedical.  Order 
Fluke Biomedical Part Number 07-453SC.  Alternatively, a 2.5mm mono phone plug is available from 
many vendors including Mouser Electronics, Part No. 177PP095.  An oscilloscope probe can be clipped 
to this part. 
 
The Remote Sensor available from Fluke Biomedical is particularly useful when observing the x-ray 
output using an oscilloscope.  Order Fluke Biomedical Part Number 07-453RS.
