The VLF CR-28, VLF CR-40, and VLF CR-60 are portable, high-performance, and energy-efficient cosine rectangular VLF cable test systems.
Design for testing cables with 0.1 Hz cosine-rectangular voltage according to IEC, IEEE, and CENELEC standards, these test systems are ideal for testing the dielectric strength of cables and joints after installation or repair.
These test systems have high test capacities and yet manage to be compact,because of the patented voltage wave-shape and the power recycling during polarity reversal. Aside from cable and sheath testing, the test systems can also be used for the precise pinpointing of sheath faults (in combination with a step-voltage probe).
There are three portable systems available, each with different voltage levels (28, 40, and 60 kVrms):
• Clear and chronologically ordered activity history
• Dedicated timeline view for single cable
• Modern UI with two themes
• Compatibility with the new generation of test vans (updates also available) and VLF testers
• Possibility to define own evaluation criteria for VLF tests and TanDelta measurements
• Cable condition assessment
• Top-notch search and filter functions
• Custom curve colours
• PDF import
• Database backup solution

⦁ Improved distance filtering
⦁ Simplifications in license activation and management
⦁ JSON file importing improved.
⦁ Improved scaling of PDF preview
The setup file below is suitable for the installation of both MeggerBook (full version) and MeggerBook Lite (free limited version). For further information read the MeggerBook quick start guide
When started with after adding the electronic license key into the installed software, the software starts as MeggerBook full version which allows for easy and comprehensive data evaluation, data archiving, cable management and report creation. A personal quotation for a certain number of licenses can be requested here . The new electronic license key allows for 3 devices to have MeggerBook full version installed on them.
The dongle key licenses from older versions of MeggerBook are not supported with this newer version. Updated electronic license keys can be requested here for previous customers.
Without the required software license key the software starts as MeggerBook Lite which allows for seamless report creation and offers some of the features as the full version while limiting the data storage options as follows:
• Measurements, analyses and reports are not permanently stored in the database
• While cable import and storage are not limited, a maximum of 5 cables can be created using the cable editor of the Lite Edition
At this time, the software can handle the measurement and test data of the following Megger devices:
Test vans: Centrix, Centrix City, Compact City, R30, Variant
Test systems: VLF Sine Wave 45 / 62, VLF CR 40/60, TDS 40/60
TDRs: Teleflex VX(-P), Teleflex SX
Note for test systems VLF Sine Wave 45 and VLF Sine Wave 62:
Data of these test systems can only be imported into the software, if the test systems is equipped with firmware version 3.14 or higher.
