The LEDs I
P
, I
Q
, RS and FR on the MRIK3-ICE and
MRI3-ICE emit a yellow light, all other LEDs are bi-
coloured. The LEDs at the left next to the alphanumeri-
cal display give a green light during measuring and a
red one when a fault signal 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.
