STATUS INDICATOR LED

The M2XRP2 is provided with a status indicator LED which
blinks in different patterns indicating various status of its
CPU.
When it is functioning within normal parameters, the LED
blinks in a regular pattern of ON and OFF. The high levels
mean that the LED is ON, while the low levels means OFF

MAINTENANCE

Regular calibration procedure is explained below:
■ CALIBRATION
Warm up the unit for at least 20 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the "ADJUST-
MENT PROCEDURE" explained earlier.
