Description
1
Erase memory.
2
Load standard oilfield setup.
3
Enter pipe ID (inches).
4
Standardize the gauge on air. When complete, fill pipe with
clean water. Allow detector to stabilize for five minutes.
5
Calibrate on water.
6
Record the water/air ratio.
7
Use pipe size and water/air ratio to obtain the factor from the
tables
(Appendix
8
Clear "Cal Point Pending" message.
9
Reset CAL/REF ratio to 1.00.
10
Standardize the gauge on water.
11
Record the water signal value.
12
Calculate the ZnCl signal value: ZnCl = Water signal * Factor.
13
Enter the calculated ZnCl signal value.
14
Hold the output at ZnCl signal value.
15
Displayed density should be near 1.812 g/ml. (Record value.)
16
Record the slope correction factor.
17
Record the carrier specific gravity.
18
Displayed density should be 1.812 g/ml. Adjust slope
correction factor if necessary until density is 1.812 g/ml.
19
Clear all holds.
20
Displayed density should be 1.000 g/ml. (Record value.)

Following is a condensed version of the procedure detailed in
is assumed that the gauge has been installed properly, the shutter is open (if
applicable), and the pipe is empty of any fluid.
