CTE-4000 is a stationary battery analyzer that measures the conductance and voltage of 2V, 4V, 6V, 8V & 12V sealed lead-acid batteries for security systems, emergency lighting, mobility vehicles, uninterruptible and power suppliesto identify those that:
. Are good.
. Are serviceable
. Need to be replaced.
2.1 The analyzer measures the status of a batteryin voltage and conductance values. It displays conductancevalues in Siemens (S).Ampere hours (Ah) are a typical measurement of jar capacity; however, they are difficult to measure without knowing the load to which the jars supplypower. Lancol recommends that you use a reference value to compare the conductance value to the testresults. A reference value is a typical conductance value for the type of jars you are testing. For moreinformation about determining a reference value, refer to “Chapter 2: Pre-testing.”
CTE-4000 has an operating range of 10-5000S.
CTE-4000 can store 1000 groups of test results, and you can output the test results to your computer with the USB cable.
Voltage Range: 1.8 -16.00 Volts DC
Accuracy:+/-2% across test range, Voltage and Conductance

Chapter 2: Pre-testing
Before you test a site with the analyzer, you need to Determine a reference value.
Note: make sure the battery you are testing is 12V batteries.
Using the percentages of the reference value
You can use the percentages of the reference value to help you determine the strength of the site. Table 6 lists ranges of reference value percentages, and the action you should take.

Serviceable with maintenance
Check for problems and refer to
• Test results or other information about the site to determine the cause of low readings.
• Your company maintenance procedures for battery maintenance
• IEEE standard 1188-1996: Recommended Practice for
Maintenance, Testing and Replacement of valve-Regulated,
Lead-Acid (VRLA) Jars for Stationary Application
Replace the jars. Refer to your company jar replacement procedures or IEEE standard 1188-1996.
Note: The above recommended maintenance standards are not national standards, according to the user's own risk-bearing capacity to adjust the scale standards, reduce the use of risk.
