See attached view of a simple wooden V-block setup, which is held by a clamp or vise. Place the laser in something like this and aim it at a vertical surface 5m or so away. Hold it reasonably firmly down in the V and turn it slowly. You will probably see the laser dot wander round in a circle. Using an allen key adjust the laser alignment with the recessed grubscews you should find around the laser housing, until you cannot see the laser dot wander.
The V-block device does not need to be especially accurately made, but it should be rigid, have surfaces hard enough not to deform easily, and be firmly clamped during the test. The procedure is more sensitive over a longer baseline, and i have found it to be repeatable to within 1mm or so over 5m. I use the inside of the garage door.
I found also I had to re-collimate the laser collimator after replacing the batteries, which were 3 button LR-44 (it is a Bintel type)
