discharge through electronic load or resistor. With this tester, the battery manufacturer can
test batteries easily. After selecting the battery type, voltage and capacity are selected, the
tester can start the smart discharge to discharge the battery safely.
5. Program DC Power
After this function is selected, the tester can be used as a precise digitally-controlled DC
power supply unit. The maximum output voltage is 20V (BTS-2004H) or 10V
(BTS-2002H); the maximum output current is 2A. You can set the output voltage and
limited current directly. The tester can be easily used for special charge and test of battery
and power supply of other devices, thus enlarging the application scope of the tester.
6. Program E-load
After this function is selected, the tester can be used as a precise digitally-controlled
electronic-loading unit. It can work in these modes: constant current, constant voltage,
constant resistance, and constant power. In the modes other than constant-voltage mode, the
cut-off voltage can be set to facilitate the measurement of battery discharge. When the load
voltage is lower than the cut-off voltage, the operating current can be cut off to avoid the
damage caused by deep discharge of the battery. Besides, this tester can be used in
occasions where electronic load is needed, for example, recharger test and aging test of
switching power supply.
7. VOL and IMP
After this function is selected, the tester can be used as a general 3 1/2 digital voltmeter or
a
digital milliohm meter
. It can continuously indicate the input voltage and battery impedance,
and the resistance value of two identification resistors. It can be used in place of a special
impedance meter for fast screening and detection of batteries.
8. Enter Calibration
After this function is selected, the tester can be calibrated without removing the outer shell,
thus to ensure high measurement accuracy. The following items can be calibrated: voltage
measurement, impedance measurement, charge current measurement, discharge current
measurement, and so on. Before the use of this function, it requires the user to input a
confirmation password to avoid unauthorized operation.
.
9. Read ID (Currently, this function is available for DS2502 only and applicable to the
batteries used in MOTO mobile phones.)
After this function is selected, the tester can read all the internal data of DS2502. It
real-time displays the data of any address and the last CRC data. By comparing the CRC
data of the last two bytes, you can judge whether the transmitted data is correct.
