+BringUp Powermeter
+##################
+
+In case your charger prototype has a power meter, it may be a good time
+to verify its functionality as well now - even though it is not strictly
+necessary for charging.
+
+Write a bring-up config for your power meter and start it the same way
+as described in :ref:`htg_bring_up`. There are a few examples you can copy
+and modify, e.g. ``config-bringup-DZG.yaml`` or ``config-bringup-LEM.yaml``.
+
+.. code-block:: bash
+
+   /etc/everest/run_tmux_helper.sh /etc/everest/bringup/config-bringup-mypowermeter.yaml /usr
+
+Your setup should look like this:
+
+.. image:: images/bring-up-powermeter.png
+   :alt: Bring-Up Powermeter
+
+Complete the following steps:
+
+- Verify that the measurements come in regularly (e.g. every second).
+- Imported energy in Wh and timestamp are the only required values.
+  Verify they are correct. For bidirectional metering, also verify the
+  exported energy values.
+- Validate the other reported measurements.
+- If supported by the power meter (e.g. for
+  :doc:`German Eichrecht </how-to-guides/eichrecht>`), click
+  on “Start Transaction”. Verify that it replies correctly, and verify
+  the time to reply is less than a few seconds.
+- Click on “Stop Transaction” and verify the reply. The reply should
+  not take more than a few seconds.
+- Apply some test load if possible, and verify that the flow
+  direction of energy is correct. A common mistake is to swap input and
+  output of the meter. If you don’t have a test load, you can also test
+  this when doing the first charging tests with a real car.
