Lasermet's Advanced Digital Laser Power and Energy Meter - the ADM1000 - now has a PC Interface program enabling users to view and measure more data more accurately.
By extending the user interface to a PC, waveforms can be seen in greater detail and the results can be saved either as an image (bmp, png or jpeg) or as data in a csv file. By saving the data in Excel format the waveforms can be recalled and displayed as required.
Control from a PC
The power range and meter mode functions can be set directly from the PC - one of these options being to set the meter to display average readings or peak power over a period of time.
To record long term variations the data logging functions can be used including the ability to set the logging duration whereby the logging function can be left to run and it will switch off at the end of the designated period. The data logging (.csv) file is subsequently retrieved and can be viewed as a graph. (See illustration).
The graph on the PC can show 250 points compared to 100 on the meter display and the vertical display has a greater resolution. Trigger levels can be adjusted using a slide control facility on the PC screen and the trace zero level can also be shifted enabling the waveform to be viewed in a similar way to an oscilloscope.
On screen cursors can be selected and used to take measurements from the trace to provide figures for power difference, time difference, frequency and energy. Also, screen graph colours are selectable.
