3-1 Measurement Errors
The following tables list the error messages that may occur during a monitoring session and offer
information on possible causes and corrections.
Measurement errors may be shown on the blood pressure data list display and printed text data. If
an error occurs (indicating by asterisks), corrective measures must be taken to use this software.
3-1-1 TM-2420/TM-2421 Error Codes
ERROR CODE POSSIBLE CAUSE CORRECTION
E01 The microphone has become
disconnected or there has been
excessive body motion. Remove and reconnect the microphone
connector at the front of the monitor.
E02 Air leak Check that the air hose plug is tightly
connected to the air connector located
at the front of the monitor.
Check the connection between the air
hose plugs and the air bladder.
Check the air bladder for leaks.
E04 Low Battery, “c”, shown in the
monitor display.
The monitor will not take a
measurement, print data, or
download data until the monitor is
charged. Plug the AC adapter in the monitor.
The “c” shown on the display will
disappear after 30 minutes. Wait the full
60 minutes charging time to ensure that
the battery is fully charged.
Note: The monitor will hold all stored
readings in memory for two weeks after
the appearance of the low battery
indicator.
E05 Measurement time exceeds 100
seconds.
(Inflation time error) Check E01 and E02 procedures.
Reposition the lower microphone and
then correlate it to the subject.
Check that the air hose is not held down
by a constrictive strap or similar
restraint which may disrupt the air flow.
E06 Pressurization greater than 320
mmHg Confirm that the subject is not moving
during the measurement.
Clear the memory.
Caution: All measurement data will
be erased.
After clearing the memory, take one
measurement. If the cuff pressurizes to
approximately 195 mmHg, the system is OK.
Reset the monitor by gently inserting a
paper clip in the hole located on the
bottom of the monitor.
Caution: All measurement data, as
well as programmed intervals and
conditions will be erased.
If the monitor stops and then continues
to inflate above 260 mmHg, return the
unit to A&D for service.
