Labeling Type Function
OFL
LED
Yellow/off
Overflow state:
 Yellow: Overflow condition, i.e. the amplifier is near its range
limit.
 Off: No overflow condition
When the OFL LED comes on, a zero-point adjustment of the
sensor can be necessary. See p. 17 and the E-509 User Manual
(PZ77E) for details.
SERVO ON/OFF
1, 2 and 3 stand
for
the channel
numbers
Toggle switch Switch for the servo mode selection of the corresponding channel:
 ON: Servo mode is switched on (closed-loop operation)
 OFF: Servo mode is switched off (open-loop operation)
See also “Starting Operation” on p. 17.
ZERO
Trim potentiometer A trimmer adjustment tool can be used on the ZERO potentiometer
for a zero-point adjustment of the sensor. A zero-point adjustment
can be necessary after longer operation (changes in temperature)
or if the load on the piezo stage is changed.
SENSOR
