Introduction
This manual describes the operations and conditions necessary for the
proper use and working of the NEWPORT LDS1000 Controller.
It also provides the basic maintenance operations that are useful to keep
the instrument in good working order.
IMPORTANT
NEWPORT LDS series sensors are measuring instruments that provides
results of measurements. The calibration certificate drawn up by NEW-
PORT for each delivery, or when an instrument is newly calibrated must
ALWAYS be supplied with the sensor. It provides the values of the para-
meters that must be stored in the memory of the LDS1000 electronic
controller so that the instrument gives accurate measurements. BEFORE
any measuring operation, the operator must make sure that the parame-
ters that are used by the electronic controller are the ones that the ins-
trument is designed to use. Refer to the corresponding chapter to check
and modify the sensor parameters.
RECOMMANDATIONS
You are strongly advised to read the chapter entitled “First use” careful-
ly before connecting your autocollimator.

Description
The LDS1000 Controller is designed to drive sensors of the NEWPORT LDS
series (for example, LDS-Vector autocollimator or STR500-H rectitude sen-
sor). The latter are compact and self-contained measuring instruments.
The LDS1000 electronic controller provides the means of displaying angu-
lar variations by measuring the movement of a spot of light on a position
sensing device. It has the capacity, off-line, to store up to 2048 measu-
rements (14336 measurements with the extended memory option) and to
calculate the averages of these measurements.
When linked to a personal computer it provides the possibility of proces-
sing and recording the measurements.
This manual is designed to facilitate the use of the LDS1000 Controller for
all its modes of operation.
A second user’s manual exists which describes and facilitates the use of
the sensor.
