How to Do Auto Level Calibration?
Those dealing with test equipments know well about calibration. It is the checking or adjusting an equipment by comparing it with a standard- for getting accurate measurements. Auto level is one of the many survey instruments that needs calibration. Here is a step by step instruction guide on how to calibrate this survey equipment. If you want to do it yourself, this guide will help you in your auto level calibration.
- Open the cover of the instrument by unscrewing the top, bottom, left and right screws. If you only want to do collimation (adjust accurately the line of sight), then you have to adjust only top and bottom screw.

Years ago, two of the most disastrous accidents happened. The first is the nuclear leak in Chernobyl, which has infected and killed hundreds of people in Russia. The second incident but in a smaller scale is better known as the Three Mile Island, which happened near Harrisburg, Pennsylvania.
As much as people are aware of the potential dangers of nuclear power, the community still needs it. This facility as well as others that are used as a depot are essential for the livelihood of the town.

Whether you are familiar with them or not, specialty and calibration gases play a very large role in your life. Specialty or calibration gases or cal gases as some call them help monitor processes that govern our lives and keep us safe. A specialty gas or calibration gas is simply a mixture of gases that is used to calibrate a gas chromatograph. A gas chromatograph is an instrument very common in the field of analytical chemistry that analyzes samples of liquids or gases and breaks a mixture down into it’s individual components and also quantifies them. Gas and liquid mixtures are used to calibrate them. Cal gases serve two roles in analytical chemistry. First, they reveal the elution time for certain chemicals with respect to a certain set of parameters on a Gas Chromatograph (GC). Additionally, they help set response factors that allow the quantification of identified peaks in a mixture sample. So, what are some examples where cal gases used to calibrate GC’s influence our lives behind the scenes?
Commodities. Natural gas prices is the first and most common example. The pricing of natural gas is determined by the components in natural gas as well as their concentrations. BTU reference standards a prepared by chemists using known components and known concentration of those components carefully measured out so as to prepare a reference standard of known component identification, concentration as well as known BTU value per cubic foot of gas. BTU reference standards such as this are use to monitor and price the gas that passes through pipelines and ultimately to our homes.
