Labeling Type Function
T
LEMO
EPL.00.250.NTD
Input for the Target sensor signal from the piezo stage.
P
LEMO
EPL.00.250.NTD
Input for the Probe sensor signal from the piezo stage.
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.
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.
