Figure 4.7: Front plate
MRIK3-ICE
The LEDs No, RS and on the MRIK3-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 sig-
nal occurs.
The LEDs underneath the <SELECT/RESET> - push
button 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.
