BT510 Users Manual b. For other fields, push the Edit softkey, use the arrow keys to edit the value, and then push the Confirm softkey to save the value. 5. Once all threshold values are correct, push the Confirm softkey on the save the threshold set. The threshold set is applied and the T-X (X stands for value of No.) icon and the corresponding PASS/WARN/FAIL indication shows on the display. To disable measurement thresholds: 1. On the measurement screen, push the Threshold softkey to open the Select Threshold menu. The value of No. is already highlighted. 2. Use  to set No. to ---. 3. Push the Confirm softkey. The T-X icon no longer shows on the display. How the Thresholds Work When a threshold set is applied, the Product compares each resistance reading with the resistance reference in the current threshold set. • If the reading is greater than reference x (1+Fail threshold) or less than the resistance lower limit, the comparison result is FAIL, indicating that the tested battery is potentially compromised and should be further investigated. • If the reading is greater than Reference x (1 + Warning threshold) but less than Reference x (1 + Fail threshold), the comparison result is WARN, indicating that the tested battery requires further attention and increase in test frequency. • If the reading is less than Reference (1+ Warning threshold), the comparison result is PASS, indicating that the tested battery is within the defined tolerance limits. For example, you have applied a threshold set where Resistance Reference is set to 3.00 mΩ, Warning set to 20 %, Fail set to 50 %, and low limit set to 2.00 mΩ. The comparison result is FAIL for resistance readings greater than 3.00 x (1 + 50 %) = 4.50 mΩ. It is PASS for resistance readings less than 3.00 x (1 + 20 %) = 3.60 mΩ. It is WARN for resistance readings less than 4.50 mΩ but greater than 3.60 mΩ. At the same time, the Product compares each stable voltage reading with the lower voltage from the applied threshold set. If the reading is less than the lower voltage threshold, the comparison result is FAIL. If the reading is greater than the threshold, the comparison result is PASS. Note If the resistance test and the voltage test have different results, the Product shows the worse result on the display. For example, the resistance indicates PASS but the voltage indicates FAIL, the Product still shows FAIL on the display. 3-12 MyFlukeStore Shop for Fluke products online at: www. .com 1.888.610.7664

How the Thresholds Work
When a threshold set is applied, the Product compares each resistance reading with the
resistance reference in the current threshold set.
•
If the reading is greater than reference x (1+Fail threshold) or less than the
resistance lower limit, the comparison result is FAIL, indicating that the tested battery
is potentially compromised and should be further investigated.
•
If the reading is greater than Reference x (1 + Warning threshold) but less than
Reference x (1 + Fail threshold), the comparison result is
WARN
, indicating that the
tested battery requires further attention and increase in test frequency.
•
If the reading is less than Reference (1+ Warning threshold), the comparison result is
PASS
, indicating that the tested battery is within the defined tolerance limits.
For example, you have applied a threshold set where
Resistance Reference
is set to
3.00 m
Ω
,
Warning
set to 20 %, Fail set to 50 %, and low limit set to 2.00 m
Ω
. The
comparison result is
FAIL
for resistance readings greater than 3.00 x (1 + 50 %) = 4.50
m
Ω
. It is
PASS
for resistance readings less than 3.00 x (1 + 20 %) = 3.60 m
Ω
. It is
WARN
for resistance readings less than 4.50 m
Ω
but greater than 3.60 m
Ω
.
At the same time, the Product compares each stable voltage reading with the lower
voltage from the applied threshold set. If the reading is less than the lower voltage
threshold, the comparison result is
FAIL
. If the reading is greater than the threshold, the
comparison result is
PASS
.
Note
If the resistance test and the voltage test have different results, the
Product shows the worse result on the display. For example, the
resistance indicates PASS but the voltage indicates FAIL, the
Product still shows FAIL on the display.
