Read full description

Version 5 of the INTspector app from KRIWAN represents the logical further development of the operating software for KRIWAN diagnostic devices. The app provides you with comprehensive insights into your devices and systems, from compressors to industrial pumps to refrigeration systems. Whether fault analysis, switching cycles, or operating times - with the INTspector app, a wide variety of data and measured values can be analyzed in detail and also recorded over a longer period of time in order to map and report processes transparently.   Functions (requires a DP gateway): • Read data directly from the system. This gives you access to the error memory/counter, you can assess the current status of the system and view the operating data. • Create a report in PDF format in no time at all and forward it directly to your customers if required. • Optimize your system by adjusting the parameters • Have the actual values recorded over time in order to assess the system's behavior (live diagnosis). Other functions (requires no gateway): • Call up the data sheets, interface descriptions and parameter lists for the installed KRIWAN products so that they are available quickly and without paper for maintenance and repair work in the system. • Analyze the status of the compressor using the LED flashing code, set the flashing code and the current error will be displayed directly.
