Page 3: Description
The Model 815 automatically resets at the beginning of each exposure, holding the reading until the next exposure. The most convenient way of using the 815 is to place it directly under the x-ray head. Step back, take the exposure and then observe the reading. Refer to the section on Operation for information on how to obtain the most accurate measurements. -
Page 4: General Instructions
When the instrument is first powered on, it is in “Normal” or “High Speed Mode” which is used for most measurements. When used in Normal Mode the Model 815 inserts a delay of about 22 milliseconds before measuring the kVp. Pushing the button once will put the instrument into “High Resolution Mode”. In High Resolution Mode, the delay is approximately doubled. -
Page 5: Operation
Refer to Appendix A for more information. 1. Current (mA) The Model 815 will operate down to approximately 7 mA if the x-ray is focused properly on the x-ray target. The best accuracy is obtained at 10 to 50 mA. - Page 6 Exposure Time Measurements The Model 815 measures the Exposure Time each time a kVp measurement is made. To display the Exposure Time after an exposure, momentarily push the white Mode pushbutton switch. The exposure time will be displayed in milliseconds (ms). In normal or High Speed mode, exposure times less than 40 ms cannot be measured.

Page 7: Filtration Correction
FILTRATION CORRECTION (kVp Measurement) The Model 810 Meter is calibrated for tungsten tube x-rays with 1.5 mm of Al filtering. When the x-ray has different filtration, refer to the table below and make the appropriate correction to the kVp reading. At 50 mA Added 60 kVp... -
Page 8: Bluetooth Remote Monitor
In order to use the Remote Monitor, an application (app) must be installed on your Android phone or tablet. This feature is installed on Model 815 kVp Meters serial number 646 and up and Model 820 kVp/mA Meters serial number 329 and above. -
Page 9: Saving Data
If you are using a model 820 meter, mA and mAs will also be shown. Note: when using a model 815 meter, mAs will display as N/A (not applicable). If the data extends beyond the size of the screen, you may swipe vertically or horizontally to scroll through it. -
Page 10: Status Messages
"Low Batt" indication shows in the display. Long life alkaline batteries are available from ECC. We also carry extra long life Lithium batteries. Any standard AA batteries can be used in the 815. To prolong battery life, turn the instrument off when not in use. -
Page 11: Warranty
Time Meter from defects in materials and workmanship for a period of 2 years. There is no warranty on the battery. ECC will replace or repair any Model 815 during the first year after shipment that does not show obvious signs of abuse. -

Page 13: Appendix A
APPENDIX A Additional information for accurate kVp Measurement. Height (distance from instrument to x-ray head) This instrument can measure kVp accurately over the specified range and is relatively independent of the height of the x-ray tube above the instrument. However, there are limitations that must be taken into account. - Page 14 For dental x-rays with an output from 7 to 15 mA, place the instrument ½ to 2 inches (2 to 5 cm) under the cone. For kV of 40 to 50 kV, 15 to 50 mA a height of about 6 inches (15 cm) will work well. Additional height will allow measurements at high kV and mA.
