How to Correct the Problem
INP FL
background Recorder detects an input failure.
Two consecutive failures of input
1 integration (for example,
recorder cannot make analog to
digital conversion.)
1. Be sure the range and actuation are
configured correctly.
2. Check the input source.
3. See input set up group in Section 4 –
Configuration, Startup, and Operation of
Recorder with Display and change the “IN
TYP” or “LD CAL” to a different type.
Enter it, loop through the status tests,
then return the input type to the original
one.
4. Recalibrate if step 3 does not clear the
error. Refer to Section 5 – Input and
Output Calibration for Recorder with
Display.
5. Replace the printed circuit assembly for
the pen.
