Chapter 2: Pre-testing
Before you test a site with the analyzer, you need to:
•
Determine a reference value
•
Set options in the
UTILITIES
menu
•
Set values in the
SET PARAMETERS
menu
Note:
Make sure the jars you are testing are 6 or 12 V jars.
Determining a reference value
Reference values
Reference values are average conductance values from a sample of strong jars similar in condition
and age. You can compare reference values to test results from a site. The differences between
test results and reference values help you determine the capacity of the site to see if it is providing
enough conductance for the load. Differences can reflect how a site’s strings were treated,
installed, or maintained.
Options
Midtronics recommends that you create your own reference values for a site to get values specific to
the site you are testing. For this reason, the following options are listed in the order you should take to
obtain a reference value.
To obtain a reference value for a site:
1. Consult your company documentation for previous reference values that were
created for the site you are testing. If you do not have previous reference values
for the site, do step 2.
2. Test a sample of jars. Refer to “Testing a sample of jars.” If you cannot test a
sample of jars, do step 3.
3. Test the jars in the site that you need to test with the analyzer and use highest
conductance value as a reference value. If you cannot test the jars for a reference
value, do step 4.
4. Use the average from
SITE SUMMARY
after you test the site. Refer to “Using
the average in
SITE SUMMARY.”
5. Contact the jar manufacturer or Midtronics for a list of reference values for
common jar types. Visit our website at: www.midtronics.com
