LEM and LEM Norma was the first partner of JHk Software. We have participated on a development of embedded software for a number of power quality measurement devices and also on a development of PC software for power quality analysis. LEM Norma is still our customer, now as a part of the Danaher corporation.

One of the most successful LEM Norma projects is an embedded system for Topas 2000 power quality measurement device - one of the first IEC 61000-4-30 Class-A standard fully compliant devices in the world. The device is currently branded as Fluke 1760.

Qualitrol overtook a control of several power quality hardware and software projects after splitting LEM portfolio between Qualitrol and Fluke brands. We have developed and we are supporting device drivers for older models of power quality measurement devices from former LEM brands and are also supporting power quality analysis software QIS.

We are developing software also for Fluke power quality branch that includes both embedded systems based on embedded Linux and VxWorks platforms and also PC measurement analysis software.

JHk Software also participates on a development of the calibration devices and related software with Fluke. Projects include specific functions for documenting process calibrators firmware, calibrator device communication and supporting PC software. We have experience from the implementation of the FDA 21 CFR Part 11 legislation compliance (US Food and Drug Administration) or HART communication protocol implementation.
