feature
1.5.7-inch VGA color LCD touch screen
The current monitor WM-EX is equipped with a 5.7-inch VGA color LCD touch screen, which provides an intuitive operation interface so that users can easily view and control various settings.
2. Various monitoring
– The current monitor WM-EX can set 2-point upper limit and 2-point lower limit to ensure safety during operation.
– Two measurement intervals can be set for one measurement, and their current data can be measured separately to facilitate accurate monitoring of changes in different parameters.
3.Maximum
The welding time can be measured up to 9.99 seconds. The current monitor WM-EX can provide real-time welding time data to help users optimize the welding process.
4. Can measure 5 points of displacement
– The current monitor WM-EX can measure 5-point displacement, including work inspection, product dimensions and 3-point displacement to ensure that the product meets specifications.
– In addition, WM-EX supports ISO-17657 compatibility mode to facilitate users to conduct standardized testing and inspection.
