The EM 6400 displays:
• Voltage:
Three voltage measurements line-to-line: 1-2, 2-3, 3-1 and average,
Three voltage measurements line-to-neutral: 1-4, 2-4,3-4 and average.
• Current: Three current measurements phase-wise: 1, 2, 3, one average current of all three
phases and three current phase angles A

w.r.t. the corresponding voltage line-
neutral vector.
• Phase wise load in %: Three currents in % of the FS (%A FS).
• Unbalanced load in %
• Frequency: Measured from whichever phase is active.
• RPM: Measures the speed of the generator.
• Power: VA, W, VAR. per phase and total. PF per phase and 3phase. Per-Phase W
readings provide a quick CT Polarity Check. A negated W phase reading indicates CT
reversal.
• Energy: VAh, Wh, +VARh (Ind), -VARh (Cap), Run Hrs, On Hrs, Supply Interruptions
(outage)
• Energy (OLD): VAh, Wh, +VARh (Ind), -VARh (Cap)
• % Average Load Bar graph: Load bar graph indicates consumption in terms of %Aavg.
Now you can quickly estimate the load by viewing the display without operating any
keys. The bar graph consists of 12 segments. Each segment indicates a load of 10% of CT
primary.
• Kilo, Mega, Giga indication
for the above parameters.
3.3.Keypad Operation
Figure 3.1 shows a flowchart of Key Operations
Then, follow these simple steps:
• First take a quick look at what the Keys do
. Try the simple example (table 2.4)
• Now, try getting around to other parameters, by moving up, down, right and left. The
readings are organized as display pages to the right of “RMS” and “INTG”.
o The “Kilo”, “Mega” and “Negative” Indicators are automatic. “Kilo” and “Mega”
light up together to show “Giga”.
• You cannot go left into the PROG menu (“RUN”) unless you enter a enter code
• Once in the PROG menu (“RUN”), you can go down to “CLR” or “SET”. Going right
though the “CLR” page allows you to clear the integrator. Similarly, keep going right
through “SET” to program the meter settings. When done:
o Go Left all the way back to the PROG menu
o Go Up to “RUN”
o Go Right into RMS to view the display pages again.
