14 Troubleshooting
If the equipment is used in a manner not specified by Mettler-Toledo Thornton, Inc.,
the protection provided by the equipment may be impaired.
Review the table below for possible causes of common problems:
Problem Possible Cause
Display is blank.
– No power to M400.
– Blown fuse.
– LCD display contrast set incorrectly.
– Hardware failure.
Incorrect measurement readings.
– Sensor improperly installed.
– Incorrect units multiplier entered.
– Temperature compensation incorrectly set or
disabled.
– Sensor or transmitter needs calibration.
– Sensor or patch cord defective or exceeds
recommended maximum length.
– Hardware failure.
Measurement readings not stable.
– Sensors or cables installed too close to equipment
that generates high level of electrical noise.
– Recommended cable length exceeded.
– Averaging set too low.
– Sensor or patch cord defective.
Displayed a is ashing.
– Setpoint is in alarm condition (setpoint exceeded).
– Alarm has been selected (see chapter 8.5.1
“Alarm”) and occurred.
Cannot change menu settings. – User locked out for security reasons.
14.1 Changing the fuse
h Make sure that the mains cable is unplugged before changing the fuse. This operation should
only be carried out by personnel familiar with the transmitter and who are qualified for such
work.
If the power consumption of the M400 transmitter is too high or a manipulation leads to a
short circuit the fuse will blow. In this case remove the fuse and replace it with one specified
in section 15 “Accessories and Spare Parts”.
