2,APP Download:

IOS APP:search "UM meter" in iPhone APP store

Android APP: search "RuiDeng" in google play

1,Correct Usage

use the meter in the correct way, USB2.0 support Huawei quick charge. there is type-c in and type-c ouput port, it can measure type-c cable , support type-c charge , but not tuype-c charger identify resistance , no trigger function. When you use USB-C in , you must use USB-C out, and if you want want fast charge by type-c port , you must use PD charger too, if you just connect USB-C in to the PD charger, the meter will not light, you need to connect a load which also supports PD charging, the meter will light


2,Phone requirement

For Android and IOS APP :

A: APP only support android 8.0 and above; IOS 8 and above .

B: Allow APP to do in the background, not be cleaned.

C: Allow APP self-starting.

D: Allow APP stay after screen locked, not be cleaned.

E: For desktop, when you use the bluetooth adapter to make bluetooth connection, Please don’t use the adapter own driver, and use the windows system bluetooth driver, otherwise the module can’t make SSP series port communication. If you have installed the adaptor driver, you can uninstall it and unplug the adaptor, then plug in again, the system will install it automatically.

Operating Instructions

When the unit is first powered on the welcome screen is  displayed followed shortly by the main interface screen.
Hidden interface: Pressing any button whilst powering on the  module will display three options. Option 1 selects the Chinese  Interface and option 2 selects the English interface.
The third option is to reset(after reset, system setting data  was restored to the factory setting, all the stored data was not  reset).Release the button at the desired selection. Pressing  and holding the button after stepping to the third option will exit  the hidden interface.


Interface 1: Main Measurment Interface.(As shown below)


7:Voltage Measurement
8:Current Measurement
9:Accumulated Capacity
10:Accumulated Energy
11:Temperature Measurement
12:Number of the Data Group in use
13:Load Equivalent Impedance
14:Power Measurement
Press the ‘ ? ’ button to enter the interface as shown above:
Press and hold the ‘NEXT’ button to switch Data Group. The USB tester can provide a total of 10 groups of data to save and  view. These are numbered 0-9.

With Data Groups 1-9 selected the current mAh and mWh are saved after power off. They will continue accumulating the next time the tester is powered on. When the data group selected is 0 then the current value of mAh and mWh will be temporarily saved at power off. When the device is next powered on these values will be recalled and will begin flashing. When the accumulated mAh exceeds 1 mAh, the previous data will be cleared and accumulation will restart.
With a Data Group selected, press and hold the ‘PREV’ buttonto clear the mAh and mWh. (As shown)
Press ‘NEXT’ to switch to the Quick Charge Recognition Interface.

Interface 2: Quick Charge Recognition Interface

15:D +: (DP) data positive signal level.
16:D-: (DM), data negative signal level.
17:Mode display
D+ and D- data are only for reference , not very accuracy.
The product will automatically identify a device with a supported fast charging mode. At this time the device supports the QC2.0、QC3.0、APPLE 2.4A/2.1A/ 1A/0.5A、Android DCP、SAMSUNG.  (Note: This quick charge agreement recognition model is for reference only, because cell phone updated quickly, it can't be absolutely accurate identification)

Press ‘NEXT’ to switch to the Charging Recording Interface.

Interface 3: Charging Recording Interface

18:Accumulated Capacity
19:Accumulated Energy
20:Time display:The total accumulated recording time
21:Capacity/Energy statistics trigger current
22:REC:recording status indicator. ‘REC’ displayed in red indicates that recording is stopped. ‘REC’   displayed in green indicates that recording is in progress.
After power on, when the current flowing is greater than the Low Current trigger value. The system automatically begins to    record the accumulated capacity, energy, and time elapsed. The ‘REC’ indicator will change from red to green.
To set the Current trigger value, press and hold the "Next" button to highlight the value then press the ‘PREV’ button to adjust the  value as required. The value can be set anywhere between 0.01A- and 0.30A. (10mA to 300mA).
Press "Next" button to switch to the Data Connection Cable impedance Measurement Interface.

Interface 4: Data Connection Cable Impedance Measurement Interface.

The Tester can use differential voltage method to  measure the resistance of a data connection cable
23:USB Tester directly connected to the power  supply with Voltage and Current values displayed
24:USB Tester connected via a data connection  cable with Voltage and Current values displayed.
25:R: Data Connection Cable resistance
Measurement procedure:
First, connect the USB Tester directly to the power supply and adjust the appropriate load current (recommended value 1A) .  Press and hold the ‘NEXT’ button to begin recording data. The indicator prompt will stop flashing .
Second, unplug the USB Tester and then reconnect it to the power supply via the Micro USB/Type-C IN data connection cable  and adjust the load current to the same value as in the first step. Press and hold the ‘NEXT’ button to begin recording data. The  indicator prompt stops flashing and the Data Connection Cable resistance measurement test is completed and the value  displayed.
Note: If during the second step the screen turns black, this indicates that the voltage difference is too high and the tester will enter the 4V power-down state. The load current needs be reduced. Then re-start the measurement from the first step. After the Data Connection Cable resistance test is completed, the Tester needs to be powered off and then on again to resume measurement.
Press the ‘NEXT’ button to switch to the Measurement Graphing Interface.

Interface 5: Measurement Graphing Interface

This interface displays the voltage measurement over time in the  4-24V range and will automatically adjust the displayed range in  real time to account for voltage fluctuations. And the current  measurement over time in the 0-5.000A range and will  automatically adjust the display range in real time to account for  current fluctuations.

Press and hold “NEXT” to switch to D+D- graphing, as picture
This interface displays the D+ /D- voltage measurement over  time in the 0-3.3V range and will automatically adjust the displayed range in real time to account for D+/D- voltage fluctuations.
Press the ‘NEXT’ button to switch to the system parameter setting interface.

Interface 6: System Parameter Setting Interface

26:Auto screen off time
27:Screen brightness
28:Temperature display C /F
29:Theme background color
30:Theme foreground color
Press and hold the "Next" button to enter into setting  state, press “NEXT” button to step through the  options of auto screen off time, brightness level, temperature display units, theme background color and theme foreground  color. Stop on the value you wish to change then press the "PREV" button to change the setting.
For auto screen off time setting press ‘PREV’ to repeatedly step though the 10 options from 0 to 9 minutes. Default time is 1  minutes.
For the screen brightness setting, press ‘PREV’ to repeatedly step though the 6 options from 0 to 5 where 0 is the lowest brightness level and 5 is the highest. Default brightness is 4.
For the temperature display units, pressing the ‘Next’ button toggles the setting between C and F. default temperature unite is C.
For theme background color, press ‘PREV’ to repeatedly step though the 7 options from 0 to 6 where the color sequence is red, green, blue, yellow, light blue, pink, white and black. Default color is 2, blue.
For theme foreground color, press ‘PREV’ to repeatedly step though the 7 options from 0 to 6 where the color sequence is red, green, blue, yellow, light blue, pink, white and black. Default color is 6, white.
At any setting state, press and hold the ‘Next’ button to exit the settings menu.
