For Low mA stations (from 10 mA to 80 mA) ( E03 Memory Location):
1. Enter in Auto-calibration mode by pressing the “Auto Calibration” button
on the GSM menu and select the E03 Memory Location. Confirm all the
following screens.
2. When Auto-calibration is activated, “Auto Calibration” button is lighted
and the “3.5 mAs” value is shown on the screen.
3. Perform the following steps:
a. Make an exposure (technique parameters are pre-programmed at
80 kV, 32 mA and 100 ms and they can be shown when pressing
the “Prep” button).
b. Read the mAs measured on the mAs Meter.
c. Read the Filament Current Number shown on the calibration
panel.
d. Increase or decrease the Filament Current Number (by pressing
the “Increase” or “Decrease” buttons) to determine the correction
needed to obtain a value between 3.00 and 4.00 mAs in the mAs
Meter after making a new exposure.
e. Repeat the above steps until a proper mAs value is obtained in the
mAs Meter.
4. Enter the mAs value read in the mAs Meter (it must be a value between
3.00 and 4.00 mAs) in the mAs Display pressing the “mAs Increase”or
“mAs Decrease” buttons.
5. Exit from Auto-calibration mode pressing the “Auto Calibration” button.
At this moment, the Generator will calculate and store the new value in
E03 Memory Location. Auto-calibration is deactivated and the p rocess
is finished when the screen shows the GSM menu.
6. Press the “ Manual Calibration” button. Select an available workstation
(WS) and press the “ OK” button. Then, select the E03 Memory Location
and read its new value on the Calibration Display. Record this value in
the Data Book.
7. Exit calibration mode.
