Product Pre cision
bit accuracy measurement is more accurate
Power/capacity record (no power loss)
1.4 group capacity / power data record
2. Histogram / list for easy comparison of data
3. Controllable recording switch, automatic recording (can set threshold) or manual recording
4. Optional recording time, that is, recording for a period of time (can be set, for example, one hour),automatically stop recording.
5. Can set the recording time interval, such as saving 1 time / second or 1 time / 2 seconds
In the automatic mode, it is not possible to start or pause recording by pressing the button, but when the current ≥ recording current threshold, it is automatically recorded;
In manual mode, you can start/pause recording by clicking the K1 button, and the recording current threshold at this time does not work.
In the above two modes, the recording time can be set. For example, if it is set to 1 hour, the recording time will not be recorded after the recording time reaches 1 hour. To continue recording, clear the data.

Functional description of this interface
1. Click K2 to turn the page;
2. Click the K1 button and the system settings can set the capacity/power record to start manually or automatically.
When manual:Click K1 to start/pause recording;
Automatic:Click K1 to not respond;
3. Press and hold K1 to clear the currently selected group data to 0.
4. long press K2, you can switch to the histogram / table interface.
Column chart Table Interface
Histogram / Table Interface
Histogram
The capacity and power are expressed in two colors, the unit is as follows, the measurement length is 65 units, and the calculation formula is as follows
Capacity
Red:x, unit:200mAh;
Yellow:y, unit:2000/65=30.76mAh;
Capacity:=2000*x + 3.07 * y(Wh)
Electricity
Blue:x, unit:200Wh;
Green:y, unit:200/65 = 3.07Wh
Electricity = 200 * x + 3.07 * y (Wh)
Form interface
The data of each group can be directly compared according to the data value;
Functional description of this interface
1. Click K1:up data clear window. Press K1/K2 to clear the current selected group data to 0/cancel.
2. Click K2:Switch group;
3. Long press K2:Histogram/table interface switch;
4. Long press K1:return to the capacity/power record interface
