Is there a way to place a PM800, CM3000, and CM4000 meter in test mode (demo mode) to simulate a load?

Issue
Is there a way to place a PowerLogic meter in test mode (demo mode) to simulate a load?

Product Line
CM3000
CM4000
PM800

Environment
Powerlogic meter modes

Cause
Simulating a load for a Powerlogic Meter

Resolution
The Series 3000, 4000 Circuit Monitor (CM3000 (CM3), CM4000 (CM4)) and the Series 800 Power Meter (PM800 (PM8)) have a load simulation mode that can be enabled. The 3 phase load simulation will be based on the CT and PT ratios that are in the meter prior to enabling the simulation.
*Note: PM800 firmware revisions 12.000 and 12.200 do not support demo mode.

How to enable the simulation mode using SMS or a Modbus communication utility:
Write a decimal value of 2 to register 8001
Write a decimal value of 32320 to register 8000.

How to enable the simulation mode from the front panel display of the meter (refer to the device reference manual for instructions on Reading/Writing Registers):
Write a decimal value of 2 to register 8001
Write a decimal value of 32320 to register 8000.
Exit the register write mode but do not save changes. The meter will reset if changes are saved and the simulation mode will be disabled.

The register write/read screen can be accessed by going to Maintenance (Maint), Diagnostics(Diag), Register (Reg) then entering the password, which is default 0. The register being written to can be changed by using the + soft key to increment the number by one. The <--- soft key can be used to increment the cursor by a factor of 10 (1 to 10 to 100 to 1000). Once the correct register is selected scroll down to the decimal value by pressing the ok soft key. Using the same procedure that was used to change the register value, change the value to be stored into the register. After the value is entered press ok until the cursor returns to the top.This will write the value to the register.

To disable the simulation mode:
Write a decimal 1110 to register 8000 or cycle control power to the meter.
