Commands for Controlling the RMS Values Shown on the LCD Display:
MR
METER RMS DISPLAY
CONTROL (LCD)
Description:
Allows user to select meter RMS display for voltage or current.
Usage:
MR [option]. [option]
Command
combinations:
MR1. [phase]
Displays instantaneous RMS current
MR2. [phase]
Displays instantaneous RMS voltage
Example:
MR1.3
Displays phase C RMS current.
On the D6513T3C1 Demo Boards, phase 4 is the measured neutral current.
No error message is issued when an invalid parameter is entered, e.g. MR1.8.
Commands for Controlling the MPU Power Save Mode:
PS
POWER SAVE MODE
Description:
Enters power save mode
Disables CE, ADC, CKOUT, ECK, RTM, SSI, TMUX VREF,
and serial port, sets MPU clock to 38.4KHz.
Usage:
PS
Return to normal mode is achieved by resetting the MPU (Z command).
Commands for Controlling the RTC:
RT
REAL TIME CLOCK
CONTROL
Description:
Allows the user to read and set the real time clock.
Usage:
RT [option] [value] … [value]
Command
combinations:
RTDy.m.d.w: Day of week
(year, month, day, weekday [1 = Sunday])
RTR
Read Real Time Clock.
RTTh.m.s
Time of day: (hr, min, sec).
RTAs.t
Real Time Adjust: (start, trim). Allows trimming of the RTC.
If s > 0, the speed of the clock will be adjusted by ‘t’ parts per
billion (PPB). If the CE is on, the value entered with 't' will be
changing with temperature, based on Y_CAL, Y_CALC and
Y_CALC2.
Example:
RTD05.03.17.5
Programs the RTC to Thursday, 3/17/2005
RTA1.+1234
Speeds up the RTC by 1234 PPB.
The “Military Time Format” is used for the RTC, i.e. 15:00 is 3:00 PM.
