6-20 Section 6 – Flux Density Measurement
ANALOG
OUTPUTS
(Continued) Using the Vector Summation Analog Output
Full scale for the vector summation output will correspond to the full scale
range of the channel with the highest range setting. For example, if the range
for channels 1 and 2 are set to 30 gauss, and channel 3 is set to 300 gauss;
the vector summation will associate 300 gauss with it’s full scale output
voltage setting.
Vector summation also allows the output voltage to exceed the full scale value
by 75%. This allows the possible range of vector magnitudes to be fully
represented at the analog outputs. As an example, consider all three
channels set for the 300 gauss range and each channel measuring a flux
density of 300 gauss. In this situation the vector magnitude would be
calculated as follows:
V
sum
= (300G)
2
+ (300G)
2
+ (300G)
2
= 519.6 G
With a full scale analog output voltage setting of 3 volts, the output voltage
would be approximately 5.2 volts.
Note: In all cases the maximum output voltage is limited to 10 V.
Configuring the Analog Outputs
To configure the analog outputs:
1) From the main menu choose, ANALOG OUTPUTS
2)
Position the “pointer” over the appropriate “selection” and press the
ENTER key to advance the setting.
3)
For the adjustable setting, position the “pointer” over each digit in the
number and press the ENTER key to advance the setting.
