Multifunctional DC Electric Energy Tester (DC505AVW)

1) Voltage: ±0 ~ 15V(resolution 1mV) / ±15 ~ 50V(resolution 10mV)

2) Current: ±0 ~ 5A (resolution 1mA)

3) Power: 250W(MAX)

4) Current capacity: 9999Ah(MAX)

**Multifunction DC tester can be achieved:

1) DC voltage, current, two indicators of precision measurement;

2) measured by the value of the tester's power to determine the output power supply products are qualified;

3) can accurately test the battery or mobile power input and output capacity (mAH or WH).

**Machine specifications and descriptions:

1) Maximum input voltage: ± 50V, ± 50V V exceeds displayed indicates over range;

2) Display digits: 0.000 ~ 14.999V and 15.00 ~ 49.99V;

3) DC voltage measurement accuracy: better than 1%;

4) test error: ± 5 number;

5) Resolution: 1mV (0 ~ 14.999V) and 10mV (15-50V)

6) DC voltage range: 0 ~ 15V and 15 ~ 50V two tranches automatic switching;

**Power file:

1) shown in the current product of voltage and current;

2) Display digits: 999.999W and 999mW;

3) can be key to switch W (instant power) and WH (energy) is displayed.

**Current capacity file:

1) Display the current capacity by the tester (mAH or AH), that is, the cumulative current time;

2) Display digits: 999mAH or 99999.999AH;

3) Test accuracy: better than 2%;

4) You can set the stall button to start, pause (double-click to start the pause button twice), Clear (Clear button press 2S);

5) As long as there is a current display, the current capacity will automatically start counting, the current becomes zero jump automatically stops at the last value.

**DC Current file:

1) Display digits: 0.000 ~ 4.999A;
