1. ABEM WALKTEM 2 RELEASE NOTES (WUI version 1.3.7.10)
The final stages of development for the WalkTEM 2 instrument have been impacted by the Covid-19 pandemic.
As a result the decision has been made to release the product with some limitations on functionality, and
reduced support literature, but to then release a series of firmware and documentation updates to improve the
operation and customer experience in the coming months. The instrument, as it stands, is a high-specification,
fully functioning TEM device which we believe you will be happy with and we are excited about some of the
improvements to be made in the upcoming releases; we hope you will be too. If you encounter any issues please
do not hesitate to contact your local Guideline Geo representative or email support@guidelinegeo.com
Known Issues and Limitations:
A. Battery Status: Depending upon the design of the internal batteries, you may only see 92% charge on the
fuel gauge if the batteries have been charged internally (as opposed to using the external cradle).
B. Self-discharge of Batteries: The instrument has some circuitry which is only dormant on power-down rather
than completely disconnected. As such, it is advisable to remove the batteries if the instrument is not is use
for a long period of time.
C. Rogowski Coil Tests: At present, the damping resistor selection is a manual process only; after running the
test the user can plot the results and make a choice based on the shape of the decays. This is an
improvement over the previous WalkTEM but it is hoped that the instrument will be able to suggest the best
resistor in the future. We are currently training the AI algorithm to do this.
D. HighMoment_Noise_10_90ms Script: If a sounding has been made with this script, do not restart the
measurement within 3 seconds of the completion notification appearing on the screen. The TX unit will not
reinitiate within that short time frame.
A NOTE ON CALIBRATION
Again, due to the Covid-19 situation, it has not been possible to access the regular Guideline Geo calibration site.
The initial release of WalkTEM 2 instruments have undergone a laboratory-based calibration and basic
verification. Contact support@guidelinegeo.com for more information.
