E3 EEPROM error
Setup and /or calibration information does not match EEPROM
requirements. Press any display button and the scale will enter
setup mode or calibration mode depending on what information
requires updating.
If both setup and calibration information has been lost, the
scale will enter setup mode first when a display button is
pressed. After completing the setup, the scale will display E3
again until a button is pressed to enter calibration mode and
calibration is completed.
Reset the setup parameters and/or recalibrate to clear this error.
If the scale continues to display E3 after the setup and/or
calibration has been completed, the load cell is unable to save
the information and will need to replaced (call Mettler Toledo
Service)
E4 TC error
Load cell harness not properly connected, or load cell not
communicating to circuit board. Check harness connection. If
error persists, replace the load cell to clear this error (call Mettler
Toledo Service)
E5 Serial Communications (Data) error
The scale has received a character from the host with an invalid
parity. The scale will display E5 until either a display button is
pressed or another character is received. This error could be
caused by an incorrect Baud Rate or Data Bits (ASCii
parameter) selection in the scale setup. Confirm selection of the
set up parameters.
Check Wall
Transformer
For USB Communication: Does not require the power supply.
For RS232 communication: the power supply or wall transformer can be checked for
proper voltage with an electrical multi-meter by a trained technician. The center
conductor of the power supply is positive. Connect power supply to AC outlet and do
not connect to the scale. Set meter for DC voltage and check the voltage level by
inserting the positive probe in the center of the jack and the negative probe on the
outside of the jack .
Contact Mettler Toledo for
correct part number of power
adapter. Using the wrong type
of adapter may damage the
scale
