TRIBRACH ADAPTER WITH PRECISE ADJUSTER
Seco’s 2071-00 tribrach adapter allows you to set your prism target to the same height as your instrument, even when you change position. Mount your prism to the adapter, and use a ruler to measure from the bottom to your tilting axis. Adjust it up or down until it’s at the desired height. If you’re looking for a laser tribrach you can use on your next project, be sure to look at what we have at Engineer Supply.
HOW TO USE A SECO TRIBRACH ADJUSTING CYLINDERS
The first thing you’ll need is an instrument stand or tripod. You’ll also need a laser tribrach to help you adjust the instrument that you plan to use. Position the tripod, and place the cylinder on your tribrach. Put your target on the ceiling above, but it doesn’t need to be exact. Focus your optical plummet on the target, and use the bottom leveling screws to tilt the instrument until it’s pointed exactly on your target. Rotate the device 180 degrees to check your calibration, and move it back to the other side. Look through the instrument again, and adjust it as necessary. Repeat the process until the instrument is centered on your target from Point A to Point B, but make sure you check every quadrant.
