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 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.
