NOTE
A "PARAM?" message appearing in the first line of the display indicates a negative result of the parameter verification that may
be caused by interference above the permissible electromagnetic compatibility limit (see information on standardisation and
verification in section 2). In this case, voltage regulation is blocked for safety reasons.
Check the settings in order to clear the blocking. Press and hold the "SELECT" key and press the "
" or "
" key for displaying
the current settings (see section 3.2.1). Voltage regulation is reinstated once invalid settings have been corrected while cycling
through the menu. The status LEDs and status relays are activated, and the display shows the current measurement readings.
