General
This procedure assumes that you have completed the pre-calibration
procedures in
Once the SGD-O gauge is in service, one more operation is necessary for
proper indication of the Pounds of Sand Added and the Pounds per Gallon
indications of the gauge.
Note Reference
1. Allow carrier fluid into the pipe that the gauge is mounted on. Let the
indication stabilize, and record the density value (g/ml) shown on the
third line of the gauge display.
2. Recall the carrier specific gravity (DAC 085003). Record the value that
is displayed. (This is the value used during calibration, and you will
need to re-enter this value when the current pumping job is finished.)
Enter the value recorded in step 1. Press the down arrow and then
EXIT SETUP.
3. View the detector signal (DAC 112003). Observe the value for several
seconds to obtain an average and record it. Press EXIT SETUP twice
and enter 128003.
Enter the value you just recorded (from 112003). To enter a value in
scientific notation, enter the base first. Then press the decimal key to
bring up the E, which indicates the start of the exponent, and then
enter the exponent.
Note that this step can also be done by performing a standardization on
the fluid at this point in the procedure (DAC 121).
