DISPLAYING DATA 2-3
The 24 screens provided display data in a number of different formats.
The following paragraphs detail some of the important aspects of the
various display formats.
Interpreting Numbers in Numeric Displays
Eleven of the 24 display screens show up to 15 parameters in a list, with
the parameter name on the left, and the corresponding value on the right.
One of the screens, Total Power, uses a large character display with four
parameters on the screen. Both the ‘standard’ 15-parameter display and
the large character display show numeric values.
When displaying numeric values, the MGT can display up to four digits of
resolution. If more than four digits of resolution are required, use WinPM
software to display data. If a value is too large or too small to be displayed
with four digits, the MGT uses an abbreviated engineering notation that
uses standard metric prefixes to indicate the magnitude of the reading.
For example,
1+8(MWTPE] :EPYI
12m40.................................. 0.0124
12K40................................... 12, 400
12M40.................................. 12, 400, 000
1G240 .................................. 1, 240, 000, 000
Numeric values are displayed in base units; voltages are displayed in volts,
while current is displayed in amps. The following values, however, are
displayed in kilo units rather than base units since kilo is the most
frequently used measurement:
♦
kW
♦
kVA
♦
kVAR
When viewing these parameters with the MGT, remember that the values
are already multiplied by 1000. For example, the reading below indicates
120, 000 kilowatts,
not 120, 000 watts.
kW total...............................120K0
INVLD and N/A Messages
If the MGT is unable to read a numeric or status value from the 9700 Power
Meter, it will display either
INVLD or N/A in place of the value. INVLD
indicates that the value received cannot be displayed because it is either
too large or too small (it is below 1m000 or above 9G999).
N/A appears if
the register is not available.
