Changing the Baud Rate setting
When you reach the setting, press Set and the whole value will begin blinking.
To change it to the next choice, press Inc. You can scroll through all the choices
with the Inc key. Those choices are 9600 (default), 4800, 2400 and 1200. When
you have reached the desired choice, press Set. The new setting will be saved
and the unit will proceed to the next mode.
Analog Output Scaling (If equipped)
The POWER SERIES
Plus
has the option of analog output, which can provide an
analog signal relative to the input of the meter. The relationship between the
input and the output can be scaled by the user using the front panel. Analog
Output 1 is always proportional to the value shown on the first (top) display.
Output 2 is always proportional to the middle display, and Output 3 will always be
proportional to the bottom display. With 4-wire units, switching the display
between line-to-line and line-to-neutral will result in a corresponding change in
the analog output.
A 150V voltmeter with 0 to 1 milliamp output,
for example, has the following default settings:
PT ratio: 1 to 1
Analog Output LO: 0 Volts
Analog Output HI: 150 Volts
The LO is the input value at which the output
will be 0 mA. The HI is the input value at
which the output will be 1 mA. The charts at
right show the relationship of input and output.
