Interpreting test results
String summary (for a string of 12 V jars)
The test results in the STRING SUMMARY (STRING STATISTICS on the printout) are averages for
the jar posts and straps in the string. If you tested without a reference value, dashes appear in the
fi elds that are marked in this example with asterisks (
*
).

STRING STATISTICS
* REFERENCE : 1000S
mhos (siemens) value selected in BATTERY SETUP
JARS : 4 Number of jars in the string
JARS TESTED : 4 Number of jars tested
* AVERAGE MHOS : 775S
Average conductance mhos/siemens for the string
* AVERAGE % : 77% Percentage of the reference value for the string
* DECISION : GOOD GOOD, WARN (?), or FAIL (!)
* LOW JAR : J4 50% Percentage of the reference value for the jar (J4 = fourth jar
tested) with the lowest conductance value.
* HIGH JAR : J1 90% Percentage of the reference value for the jar with the highest
conductance value. (J1 = fi rst jar tested)
* STRING % J1 86% The string’s average compared to the highest jar (i.e., the string’s
775 avg. mhos divided by the measured 900 mhos of highest jar.
TEMPERATURE : 72 °C Temperature selected in BATTERY SETUP
AVG. VOLTAGE : 13.917V Avg. voltage of the string.
VOLTS PER JAR : 12V Number of volts per jar selected in BATTERY SETUP
STRING WARN % (?) : 70%
STRING FAIL % (!) : 60%
JAR WARN % (?) : 70%
JAR FAIL % (!) : 60%
LOW VOLTAGE: 12.600V Low voltage threshold selected in BATTERY SETUP for the string.
DC FLOAT V. : 53.50V String fl oat voltage
DC FLOAT A. : 0.047A String fl oat current (amps)
AC RIPPLE : 0.059V String AC ripple voltage
