Easy-to-use keyboard

With alphanumeric and function key, it is easy and convenient to input character or number. Otherwise, it has special keys for cursor, power, escape, illumination. and the [All] key is used for measurement and record together. The [EDM] key is for all EDM parameter settings.

Data download and upload

With RS-232C and open protocol, connect the instrument and computer or Data Collectors for easy data download and storage, moreover, with software you can upload directly to internal memory of 630 series for convenient setting out in the field.

Large internal memory and convenient file management

It can record 8000 coordinate data points or 4000 raw data points, and it is possible to record 8 files at the same time, so it is unnecessary to worry memory space for users.

Advanced distance measurement

Reflectorless EDM
The OTS 630 series can focus a visible laser beam on the object which could not to be set up reflector. Thinner laser spot aim the corner accurately; Aim the target through the gridding and fencing easily.
Long distance measurement range
With single prism, the distance range can be reached to 5000m; The offered reflective sheet is very convenient for users
