1. System "ON".
2. Set the "cassette loaded" switch to "OFF" with the Service Program:

Cassette loaded check
.
3. Trigger test exposures with the following exposure values and check the kV
values and tube current characteristic on the oscilloscope (see oscillograms).
The accuracy of the kV is
&
5% plus
&
1.5 kV during the first 5 ms of the exposure.
For mA values < 50 mA, the accuracy of the kV is
&
5% plus
&
2 kV during the first
5 ms.
The tube current must rise quickly to the set value at the beginning of the expo-
sure and run linearly during the exposure.
The accuracy of the mAs product must be
&
10%.
4. Replace the jumper previously removed from sockets X3 and X4 on P.C. board
D710.
