8.5.3 Description
1. COMMAND ERROR occurs when:
Command prefix letter is not valid
Command suffix is not valid
2. FORMAT ERROR occurs when:
Length of the message is either shorter or longer than it should be.
Any other character than “0-F” used for hexadecimal values
3. CALIBRATION LOCKOUT ERROR occurs if jumper “S3C” (on the Main Board of the Process, Strain Gauge,
Temperature or Universal meters) or S1A (on the Main Board of the rate meter/totalizer or batch meter) on the
Main Board has been removed to prohibit any changes in calibration.
4. EEPROM WRITE LOCKOUT ERROR occurs if any write (“W”) Command has been issued to the meter and
the jumper position “S3A” on the Main Board of the meter has been removed
or
External pin 10 on the rear connector “P2” of the meter has been grounded.
5. SERIAL RECOGNITION CHARACTER ERROR occurs if a new value is between 0 to 1F (hex) or larger than
7F (hex). “^“, “A”, “E”, are not valid since those are used in the special communication command “^AE”.
6. SERIAL DEVICE ADDRESS ERROR occurs if the new value is larger than 199 decimal.
7. For Process, Strain Gauge, Temperature or Universal meters, DECIMAL POINT ERRORS occur if:
New value is 0 or larger than 6 (3 when the meter is in the Thermocouple or RTD modes)
New value causes the reading offset to overflow, i.e., larger than 999999or less than -99999.
New value causes any of the setpoints to overflow, i.e., larger than 999999 or smaller than -99999.
8. For Rate meter/totalizer or Batch meters, DECIMAL POINT ERRORS occur if:
New offset values cannot be accommodated on the display with the current decimal point position.
New setpoint values cannot be accommodated on the display with the current decimal point position.
IMPORTANT NOTES:
1. The meter will not respond to a command if the command’s recognition character does not match the meter’s
recognition character.
