100mA, please access the setup mode.
Notes: If want to change stop discharge voltage, also need access setup mode.
5.- Access setup mode: press and hold "OK" key, voltage LED lamp flashing, means now In
setup mode. Press "
OK" key to select different setup function:
5.1.- Function 1 (setup battery stop discharge voltage):
Press key and key increase and decrease voltage value, press and hold key can
change value quickly. When voltage precision is 10mV less than 10V setting, over 10V, for
quickly setup voltage step value is 100mV.

5.2.- Function 2 (setup battery discharge current):
Press key and key decrease and increase current value, press and hold can
change value step quickly.
5.3.- Function 3 (save and exit):
After setup finish, press and key change the display show "ES-y", press "OK" key,
means save change and exit setup mode. if you don't want save changes, please press and
hold "OK" key for exit without save.
5.4.- Function 4 (automatic voltage recognition):
Notes: This function default is off, battery voltage is 12V or 16V, and you can open this function.
Press or key change the display show "AU-y", save and exit.
In automatic voltage recognition mode:
5.4.1 If connected battery voltage is 12V, when tester power on, BUZZER will has 1 long
tweet and 1 short tweet;
5.4.2 If connect to battery voltage is 16V, when product on BUZZER 1 long tweet and 2 short tweet.
Notes: Automatic voltage recognition only work when tester power on, change the battery need
power off, so suit in the 2 Wire connection mode.
5.5.- Function 5 (quickly test setup):
Notes: This function default is off, display show "F-00", means not use quickly test function.
Setup value is "F-01" to "F-10", mean discharge time is “1minute” to “10minute”, press or
key set quickly test time, after setup save and exit. In quickly test, quick test time is the
configure time.
5.6.- Function 6 (constant resistance mode)
Notes: This function default is off, tester automatic set PWM, to make sure discharge amp equal
to setup value.
Press key or key, display show "Cr-y", after setup save and exit. The discharge ampere
will determine by the battery voltage and the external discharge resistor, more calculation method
please refer to supplementary explanation.
6.- Finish configure, press "OK" key, LED "RUN" is on, mean the tester start battery discharging,
current can arrive to configuration value in few seconds.
Now press can switch to show different parameters in main dis play. If you want automatic
display, long press key, the BUZZER tweet means tester in automatic display mode, will
show each battery parameter in 3 seconds interval
Notes: AH and discharging time is accumulated value, digital display "." flashing, time display ":"

flashing mean in running mode.
7.- In the process of discharge, battery voltage is decrease, when battery voltage less than
configuration voltage, tester will automatic stop discharge. If use quickly test model, when
time counter to zero will stop battery discharge, display flashing and BUZZER alarm user to
check the result. Tester will show battery capacity, user can press any key stop alarm. And
press key to see each parameter test result.
8.- can reset AH to zero; in discharging time
display screen, press and hold key can reset time to zero.
Notes: Both values will automatic reset to zero after power off.
9.- Remove battery clip, product automatic power off, then can start another battery test.
10.- If user want accurate test result or test low voltage battery like Li battery, we suggest to use
3 Wire connection, in this mode need connect AUX power, other configuration is the same as
the two wire mode.
Product wire jump to 3 Wire mode, connect the DC5V power adapter,(or use your local adapter,
DC output 5~30V) system start discharging.
Notes: In 3 Wire mode, first connected the aluminum resistor and the power adapter, then
configure the parameter values, finally connect the measured battery to start test.
need to manually cleared AH and discharging time when replace the battery.

SUPPLIMENTARY EXPLANATION
1. Quickly test is the unique function of FDY battery tester, do not need battery full charged, nor
discharge to stop voltage. If battery SOC is 25% -75%, the test result has higher accuracy.
Notes: Set a suitable discharge amp value and discharge time is necessary to increase the accuracy of test
specifically, because different battery have unique discharge curve, so please try to find the best configuration
value suit for your battery, user can following three principles:
1.1. Different battery has different stop discharge voltage.
1.2. Maximum discharging amp always 1C. For exampl e battery capacity is 3AH, maximum amp
set 3A, and battery discharge time can set 1minute. Set smaller discharge amp and longer
test time will make the test result has higher accuracy, Blue Jay listed below an experience
table, for reference:
Battery types Voltage is 12V Capacity is 12AH Voltage is 3.7V Capacity is 2.5AH
Stop Voltage 10.5V 10.5V 10.5V 3.0V 3.0V 3.0V
Current 10A 5A 3A 2A 1A 0.6A
Test Time 1minute 2minutes 3minutes 1minute 2minutes 3minutes

1.3. If quickly test battery capacity has deviation, you can charge battery full, and do the full time discharging test.
1.4. You can try different Quickly test amp and test time to find the experience value of correct capacity so that
you can establish your own experience in database for test such of similar battery in your application.
2.- If the battery voltage value less than 10V, maximum current is not to 10A,
Calculate Formula: Current = Voltage / Resistance(1 ohm)
For example battery voltage value is 3.7V, maximum current value is 3.7A, you can increase current in following
two method:
2.1. Change smaller resistance, according decrease resistance value can increase discharge amp value.
Notes: when test higher voltage battery must change resistance to 1 ohm or tester will not work.
2.2. If still using the 1 ohm resistor, user can p arallel a 100uH toroid inductor. Only to make sure the toroid
nductor can reach 10A maximum current. Blue Jay also provide this inductance for user testing.
3.- FDY tester provide constant resistance test mode.
In this mode do not use PWM automatic constant current. The battery discharge directly through the connected
resistance, in this model do not use constant current, but also affect the measurement accuracy of the AH.
Current calculation Formula: Current = Battery / Resistance.
ATTENTION:
Do not Reverse polarity when you wiring!!
Do not use this test in over measurement range!!
Under full load discharge mode, the high power resistors temperature is very high, please placed
in a safe place, to prevent scalding accidents.
