4. PROGRAMMING
All units are fully programmed by the factory but there are many
features that can be programmed by the User to suit individual
applications and needs.
Programmed values and parameters are stored in non volatile
memory and are therefore retained in power down situations.
4.1 To enter the programming mode the two front buttons
& have to be pressed simultaneously and held for 5
seconds. The MultiLed now enters either the Security Code or the
LED display brightness level control screen. If the security code
has been programmed the MultiLed asks for the security code.
NOTE 1
If this is the first time unit has been programmed and or no
security code is set please proceed to page 21. Section 4.2.1.
NOTE 2
When in programming mode if the control buttons are not used for
more than 3 minutes the MultiLed returns to the measuring mode
and displays the first screen.
NOTE 3
If you do not wish to alter LED set up mode then Press again
and the MultiLed display moves to the next programming mode :-
SYS for setting input volts and amps see section 4.2.1
