The LEDs No, RS and on the MRI(K)3-C emit a yellow
light, all other LEDs are bi-coloured. The LEDs at the left
next to the alphanumerical display give a green light
during measuring and a red one when a fault signal
occurs.
The LEDs underneath the <SELECT/RESET> - push but-
ton emit a green light during adjustment and inquiry of
the setting quantities left to the LEDs. They show a red
light if the printed setting quantities right to the LEDs
are activated.
