Features:
1.Automatic calibration of current zero function
After long-term use, due to aging of the device or changes in ambient temperature, small current measurement errors may increase. The solution is to hold down the button and the breathing light is on, and an automatic calibration current zero operation is performed.
After entering the main interface, the first line displays the current voltage value, the current power and the current data group, and the second line displays the current current and the cumulative capacity respectively.

2.Overvoltage and undervoltage reminder function
When the voltage is higher than 5.3V, it will be displayed on the screen and will flash continuously, indicating that the USB voltage is too high. When the voltage is lower than 4.7V, it will be displayed on the screen, and it will flash continuously, indicating that the voltage is too low, the flashing cannot be turned off, when the voltage is normal. The range disappears automatically.

3.Capacity automatic storage function
In the main interface, if you click the back button, you can cycle through the next set of data, the tester can provide 0-9 a total of 10 sets of data to save and view.
When the data group is 1-9 groups, the current capacity is stored when the power is turned off, and continues to be accumulated when the power is turned on next time. When the data group is 0 group, the current capacity is stored when the power is turned off, and the next time the power is turned on to remind the last capacity, but When the accumulated capacity exceeds 1MAH, the last data is automatically cleared and re-accumulation begins.
In the main interface, double-click the back button (within 0.5 seconds between two presses) to enter the data viewing interface. The secondary interface displays the cumulative capacity of the current data group. In this interface, click the back button to view in turn. The next set of data.
In the data viewing interface, if you press and hold the back button for more than 2 seconds, you can clear the data in this group. If you double-click the button, you will exit to the main interface.

4.Capacity unit switching function
In the main interface, press and hold the back button for 2 seconds, release the breather light when it is lit, and switch between mah and mwh.

5.Screen flip function
In the main interface, press and hold the back button for 4 seconds, the breathing light will be on when it is turned on and off, and the screen can be flipped and automatically memorized for later use.

6.Screen off function
In the main interface, long press the back button for more than 6 seconds to release, you can turn off the screen display and enter the power saving mode. At this time, the breathing light flashes, click the button to return to the main interface.

Purchasing & Delivery

Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.
Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.
Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.
In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
