Press and hold the Power On button for 5 seconds. The X-MET8000 series powers off.
Average A Batch Of Measurements
Sometimes it is necessary to average a batch of measurements on a larger, mixed sample. It is important that all measurements use the same conditions:
• The same method
• The same measurement time.
When all the measurements are complete, it is very easy to switch between the various results. The X-MET8000 series also provides comprehensive search facilities to find a series of measurements from the results history.
Sample And Batch Names
The X-MET8000 series automatically increments an index number appended to the sample name, and uses a separate name for a batch of measurements. For example, ‘Sample Batch’ could include ‘Sample 1’, ‘Sample 2’,’Sample 3’ and so on.
Which Method?
The method defines how the X-MET8000 series analyses the sample. The available methods depend upon the version of the X-MET8000 series.
Some of the method names include ‘FP’, for example Alloy FP, Mining FP or Soil FP. This refers to ‘fundamental parameters’, which is a complex mathematical algorithm to analyse materials.
The X-MET8000 series can include auto select modes, with a ‘Mode’ suffix. If an applicable mode is available, this is the first choice for the operator. These appear at the top of the method list, and include Alloy Mode, Alloy LE Mode, Mining Mode and RoHS Mode. Modes chose the most applicable calibration for the sample.
20
X-MET8000 Series User Manual
8
The X-MET8000 series can include empirical calibrations. These are calibrations of specific elements with a specific concentration range, and include stainless steel, copper, titanium, iron and many other elements. An operator will not see these in the list of available methods. Only a supervisor can see these. An auto select mode can chose the correct empirical calibration for the sample, which makes analysis easier for the operator.
The X-MET8000 includes ‘LE’ in some of the method names, for example Stainless LE, Alloy LE FP or Alloy LE Mode. The LE refers to ‘light elements’, and these methods can analyse alloys that include magnesium, aluminum, silicon, phosphorous and sulfur.
Sometimes a mode is not able to fully measure a sample, because some of the concentrations in the sample are outside the limits for that method. If this occurs, a greater than, >, or less than, <, indicator appears next to the concentration.
When this occurs, the operator should choose an applicable ‘FP’ method. These work with a wider range of concentrations and sample types, and is the second choice for the operator.
Auto Select Modes Make Analysis Easy
Auto select modes make use of both empirical and fundamental parameter calibrations. Use the numbers in the illustrations to follow how Alloy LE Mode analyzes first stainless steel and then gold. It uses an empirical calibration for stainless steel, and a fundamental parameter calibration for gold. All steps happen automatically, and can make life very easy for an operator!
Alloy LE Mode, Empirical For Stainless Steel
These steps show how Alloy LE Mode uses an empirical calibration to analyze a stainless steel sample, and return the grade.
1. The X-MET8000 series acquires a spectrum to identify the sample.
2. It compares the identification spectrum with all the empirical calibrations to obtain a match.
3. It finds a match with the stainless steel empirical calibration, shown in green.
4. It uses the stainless steel calibration to analyze the sample and then display the results.
5. It compares the results with the grade library and finds SS316 is the best match.

Alloy LE Mode, Fundamental Parameter For Gold
These steps show how Alloy LE Mode uses a fundamental parameter calibration to analyze a gold sample, and return the grade.
1. The X-MET8000 series acquires a spectrum to identify the sample.
2. It compares the identification spectrum with all the empirical calibrations to obtain a match.
3. It does not find a match with any empirical calibration, all shown in red.
4. It switches to a fundamental parameter calibration and uses the internal calculator to analyze the
sample, compute and then display the results.
5. It compares the results with the grade library and finds 24 carat gold is the best match.

Alloy LE Mode, Fundamental Parameter For Gold
How Long For A Measurement?
The factory set measurement time of 15 seconds is applicable for many measurements. Quicker measurements for iron, copper, nickel and similar alloys require as little as 5 seconds. Magnesium and aluminum alloys need longer measurement times, for example 30 seconds or more. Complex alloys also require longer measurement times to analyze all the trace elements.
Longer measurements will always give more precise results. However, the X-MET8000 series can provide excellent results in only a few seconds. The standard deviation, STD, figures indicate the measurement precision. The longer the measurement time, the lower the standard deviation figures, the greater the precision.
At the end of the measurement time, the X-MET8000 series makes a ‘ping’ sound. It is also possible to use the internal timer to fully control the measurement. This is known as ‘Timed Assay’. The operator

pulls the trigger, and then releases it to start the measurement. The internal timer automatically stops the measurement.
When Timed Assay is off, the operator must release the trigger when the ‘ping’ sounds to stop the measurement. The Results screen refreshes approximately every 2 seconds, and the operator can decide to release the trigger before the ‘ping’ sounds to stop the measurement immediately.
Timed Assay is very useful for longer measurements and measurements with the bench-top stand. It is also useful to make sure that a batch of measurements all have the same measurement time.
It is possible to set the measurement time to zero. There is no ‘ping’ sound, and the operator must decide when to stop the measurement. If Timed Assay is off, the operator pulls the trigger to start the measurement, and then releases the trigger to stop the measurement. If Timed Assay is on, the operator pulls and releases the trigger to start the measurement, and then pulls and releases it again to stop the measurement.
