To deactivate the test mode
In this mode:
- volume pulses are generated via the optical interface of the meter. The button can be used to
toggle the energy pulse output by selecting the menu item "tEST on Wh";
- When the meter is supplied with a connected pulse input/output cable , the energy pulses are
generated in the 1st pulse output and the volume pulses in the 2nd pulse output;
- it is possible to simulate volume pulses for determination the energy measurement errors;
- it is possible to change the parameters of the meter configuration.
NOTE: when the test mode is activated by short-circuiting the contacts "SERVICE", the volume
and energy accumulated in the test mode are not added to the meter's operating mode
volume and energy readings.
