Square Root Extraction
The BetaGauge II is capable of extracting square roots
from flow transmitters or other devices that output a
squared output signal.
Before setting up a square root extraction display, you
must perform the following procedures:
 Define a unit label, or name.
 Define the expected output milliamp signal for
flows that are equal to 0% and 100%, and define
both the low and high end flow variables.
NOTE: For the following square root extraction
procedures, you must install both a pressure
module and a DC module into the calibrator.
Defining a Unit Label
To define a unit label, do the following:
1. Press CH1 or CH2 to indicate the appropriate bay
in which the DC module is installed.
2. Use the Menu key to locate the Setup menu item
User, then press the corresponding function key to
display the following screen:
In the above example:
x = the channel number of the DC module,
yyyy = the current user unit label.
CHx Ent. Unit: yyyy
