Switching over the measuring range of the PHA/TV scaling.

The following measuring ranges can be selected:

The scaling currently selected is highlighted. When choosing automatic scaling (auto), the scaling

is adapted to the biggest error (longest bar).

This soft key serves to activate the Options soft-key row.

The following functions are available:

Terminate Options

EXPERT-MODE; see section 5

The encoder can be powered INTERNALLY

(by the power supply unit) or EXTERNALLY (by

the subsequent electronics). Current setting:

encoder powered INTERNALLY

The power supply for the encoder can be switched

ON and OFF.

The terminating resistors for the scanning signals

(with TTL or HTL and 1 Vpp interface board only)

can be switched ON and OFF. The current setting is

stored in PWM 8 and reloaded after power

interruption.

The active setting is highlighted in the Options soft-key row.

Note:

The soft key

is only displayed, if the PWM 8 is part of the encoder circuit, i.e. if a

subsequent electronics (with encoder supply voltage) is connected to the encoder output of the

interface board.
