0x0000

Current analog value

0x0001

Maximum value of a recording

0x0002

Minimum value of a recording

0x0003

switching threshold

• The trigger is stopped as soon as four successive values are below

the switching threshold

0x0008

Pulse width - low: switching threshold is trigger level 1

• The trigger starts as soon as four successive values are below the

switching threshold

• The trigger is stopped as soon as four successive values are above

the switching threshold

0x8063

Hundredth sampling value (in the delivery state, 100 values are stored).

...

0x8F9F

Four thousandth sampling value (a maximum of 4,000 values can be
stored).
