1：Firmware Update
Master ARM 32 bit CPU, with USB2.0 interface of the high-end chip, to the user to set aside enough space, so that the software is more perfect, more functional, and through the computer s powerful data processing, storage capacity, so that the user experience more surprises. Can be through the ordinary mobile phone data line (Android data), the mobile phone firmware upgrade.
It makes only in high precision voltage & current detection under escort, high capacity, power, load resistance!
2：Current detection: low resistance, high precision
Usually to detect small current, the simple way is to increase the current detection resistor, so that the small current in the big resistance on the larger pressure drop, so that the biggest drawback is that the line loss has been greatly improved, for the detection of large current, high accuracy is helpless! DZ-2405A uses heavyweight imports to solve this problem ADC!
DZ-2405A uses the most advanced imported 18 bit ADC (2^17) conversion, that is, 1/10000 13 (1/131071) accuracy. In the 0.012 detection resistor, after 8 times of amplification (amplifier error 0.05%), so that the current conversion accuracy reached 0.1mA resolution. Detection range of 0-5A.
3：Voltage test: high impedance and wide voltage
Advanced ARM 32 bit CPU, 72M clock frequency, 12 bit ADC converter, in which the main voltage (Vbus) using dual channel complementary detection, so that the accuracy of the 0.001V in the case, the range reached 24V, meet the requirements of high accuracy, wide voltage range! D+, D- reached 0.001V accuracy!
4：Accurate detection: accurate calculation of battery capacity, power
In the high precision 5 digit current meter, voltage meter, under the premise of guarantee, coupled with accurate real-time clock, through the calculation of charging time and current, voltage, time, accurate calculation of the phone or charging treasure capacity, power. Instrument mass storage, up to 16 hours of voltage, current information.
5：Load monitoring: accurate calculation of load impedance, output power
We can through the real-time current and voltage, conveniently and accurately know the current load resistor, and the output power value.
6：Quick Charge Tester
Built in Quick Charge protocol, you can activate the charger QC2.0, QC3.0, 9V, 20V, 12V,, and so on, accurately determine the fast charger supports several voltage! Not just monitoring!!!
7：Dual power supply: support less than 3.6V voltage test
The instrument can provide a voltage through the input interface, and can be connected with the computer or the charger through the USB interface. Ordinary USB detector if the voltage is lower than the body of the instrument, it will make the test out of the numerical error, and even the instrument can not work! DZ2405A uses a dual power supply, and each other, you can test any voltage between 0-24V.
8：Mass storage
Can store up to 16 hours of current data
9：Smart screen protection
Instrument in 1 minute no key is pressed, the screen lights will automatically extinguished, if a button is pressed, or changes in current greater than 100mA screen lamp will automatically light up.
10：Bilingual in Chinese and English
The interface of the instrument operation is simplified Chinese , English two language choice.
Menu 1: voltage, current, capacity
Press a menu (short press), will prompt the current menu function, the menu, the display voltage, current, capacity, time information, if you want to detect the capacity of the phone battery, battery power will run out, long press function keys, clear all records, and then charge to the phone, when the phone is full, the phone capacity is tested. The capacity of the unit is (MA) mAh.
Menu 2: voltage, current, power
Menu 1 and menu 2 basic same, but the capacity of the calculation, to change the power. The difference between capacity and power is as follows:
Capacity: record current, time, unit mAh
Power: record the relationship between current, voltage, time, unit mWh
Menu 3:USB1.1, USB2.0, charger test
Instrument real-time monitoring, intelligent identification of various charger state, as well as the voltage current value, D- D+ voltage value.
Menu 4: OC3.0, QC2.0 test
The instrument is built in high pass fast charger protocol, the high pass charger test, long press the function key 2 seconds, the instrument switch voltage mode! Test will activate the high pass 9V, 12V, 20V, etc., all do not connect the phone, you can connect the false load to test. The following figure is a test of a high pass charger, with 5V, 9V, 12V three kinds of voltage function, no 20V output function!
Menu 5: current curve
Instrument records, up to 16 hours of current value, through the current curve, to view the relationship between current and time, so that we can be clear at a glance.
Tip: long press the function key for 3 seconds, remove the current curve!
Menu 6: load impedance, load power test
The instrument accurately calculates the current load impedance and its consumption of the power value.。
Menu 7: language settings
The instrument, supported by the simplified Chinese and English , long press the function keys, set to the selected language.
1: master control platform:
Real-time monitoring, voltage, current, D+, D-, power, impedance and other information, and real-time display of the waveform, we can easily analyze the mobile phone and other devices working state through the waveform! All of the automatic range, take a maximum value of the waveform, to calculate the range of the range, both to monitor the micro signal, and not over range. You can choose to convert mode 18bit, 16bit, 14bit, and the time to catch.
