If the password is incorrect, a valid response is returned but the command is not executed. Use 5555 for the password if passwords are disabled in the programmable settings.
Data Formats
If any register in the programmable settings section is set to a value other than the acceptable value then the meter will stay in LIMP mode. Please read the comments section or the range for each
register in the programmable settings section for acceptable settings.
Writing this register causes data to be saved permanently in EEPROM. If there is an error while saving, a slave device failure exception is returned and programmable settings mode automatically
terminates via reset.

Not applicable to Shark 50.
M denotes a 1,000,000 multiplier.
Meter command registers always read as 0. They may be written only when the meter is in a suitable mode. The registers return an illegal data address exception if a write is attempted in an incorrect
mode.

ASCII ASCII characters packed 2 per register in high, low order and without any termination characters. For example, "Shark50" would be 4 registers containing 0x5368, 0x6172, 0x6B35,
0x3020.
Not applicable to Shark 50.
Energy registers should be reset after a format change.
Reset commands make no sense if the meter state is LIMP. An illegal function exception will be returned.

All 3 voltage angles are measured for Wye and Delta hookups. For 2.5 Element, Vac is measured and Vab & Vbc are calculated. If a voltage phase is missing, the two voltage angles in which it
participates are set to zero. A and C phase current angles are measured for all hookups. B phase current angle is measured for Wye and is zero for other hookups. If a voltage phase is missing, its
current angle is zero.
Not applicable to Shark 50.
