NOTE
To enable factory calibration on oscilloscopes with firmware version
2.10
or above, remove jumper J205 (CAL-DIS) on the CPU board.
(See Figure 5Ć17 on page 5Ć22 for the location of J205.) If you do
not remove this jumper, the message See manual to enable FactoĆ
ry Cal" appears when you select the factory calibration routine.
Firmware versions below
2.10
do not have the calibration lockout
feature and the factory calibration routine can still execute with J205
installed.
