Who and what is the ALHV designed for ?

The CSTberger ALHV is a completely waterproof automatic laser level with a highly visible laser for both internal and
external work.
Featuring servo motors, the ALHV can automatically self level in both horizontal and vertical modes.

It is ideally suited to Builders, commercial contractors and concrete placers who can use the laser outside for the
leveling and squaring of profiles, boxing and concrete.
The highly visible beam allows it to be used inside for suspended ceilings and internal fitouts .

Functionality such as scanning, alignment, grade and rotation speeds is controlled by a remote control.

When used in the manual mode to do a single direction slope or grade, the 'up' and 'down' arrows can be pressed to make
the laser slope up or down for simple slopes like driveways and basic drainage.

What functionality does the ALHV have ?

• Automatic Horizontal Leveling - with servo motors.


• Automatic Vertical Leveling - servo leveled when on it's side.


• Plumbing - Automatically plumbs laser dot to the ceiling.


• Vertical Plumbing - Automatically plumbs laser dot to the floor when laser is used in vertical mode


• Squaring - when lying on it's side allows for 90 degree setout.


• String Line setout - when lying on it's side allows string line set out on windy days.


• Vertical plane - projects rotating vertical plane when on it's side.


• Scanning -Beam can be scanned in small arcs to give greater intensity


• Rotation Control - 0, 150, 300, 600 rpm


• Grade - the laser can be switched from auto to manual mode to allow grade overide in both axis.


• Remote control - controls laser functionality including grade input


• Manual mode - laser can be used in manual or automatic mode


• Anti drift system - indicates if the instrument has been moved


• ON/OFF - using the remote the instrument can be turned off into sleep mode

Calibration

Once shipped from the manufacturer, Accurate Instruments Optical and Electronic Service Centre calibrates all
instruments on collimators and ranges then fits them with the appropriate shockwatch, calibration sticker and
test calibration certificate. Shockwatches indicate to the user whether the instrument has been dropped.

What is the standard package ?

The ALHV package is usually available as 2 different systems.

The construction package includes the ALHV laser, shockwatch, LD440 receiver, remote control, aluminium tripod,
carry case, alkaline batteries, calibration sticker and Test calibration certificate.
The ceiling package consists of ALHV laser, shockwatch, remote control, ceiling/vertical mount, 2 x magnetic targets
rechargeable battery pack, calibration sticker and Test calibration certificate.

Optional staves, re-chargeable battery kits, ceiling mounts, etc are also available.
