CHAPTER 8
ENTERING PROGRAMMING MODE
8.1: Checksum Error—Protective Self-Checking Algorithms
This checksum error is a protective self-checking wealth algorithm designed to alert the user when a
procedure has not been correctly followed, ensuring that the meter does not display inaccurate readings.
If the control power is interrupted while in Programming Mode or the user does not completely exit, the
meter enters a checksum mode. The max LED flashes. Press
AMPS and PHASE/NEXT simultaneously
and the unit recovers. Follow the procedure to enter Programming Mode to check program data. If the
data is correct, then exit.
8.2: Password Entry
The EPM 5300P and 5200P are password protected. To enter the Programming Mode, key in the
following password:
555 .
The password entry may seem awkward at first. It is designed to be difficult to use initially. This secures
unauthorized tampering. After you become familiar with password entry, you will find it quick and easy to
accomplish.
NOTE : The meter will not store any programming unless properly exited (see Chapter 14 to Exit).
