GENERAL INFORMATION

Dear customer,
Thank you for choosing our product. In the following, we will show you what you need to consider during setup and use.
Should you unexpectedly encounter problems during use, please feel free to contact us.

SETTING UP & NAVIGATION

Simply plug in the TC66C measuring device into a USB-C interface of your device. The TC66C is immediately ready for use.

2. (K2): Press long to open or leave the menu.
   Press short to switch the menu.

3. (PWR): Power switch. When this function is activated, you can use the power supply of the system. When the function is deactivated, you can use an autonomous power supply unit. For high-precision and low-voltage measurements, you can turn this switch to OFF and use the Micro-USB-port for voltage supply.

4. (PD): PD-Switch. Set this switch to OFF when measuring a device that is being charged. Set the switch to ON to activate the trigger function.

5. Micro-USB-Port for independent power supply and for connection to the PC software.

USAGE OF THE DEVICE

2. Measured current
3. Measured charge
4. Measured energy
5. Measured load impedance| 6. Measured power
7. Measured temperature
8. Selected data group
9. Current flow direction
---|---

Press and hold the K1 button to delete the current data group value.
Press and hold K2 to change the data group.
With selected data group 1, charge and energy values are stored and will be continued when the device is restarted.
With selected data group 0, the values are also stored and displayed when restarting, the values are flashing. However, if a charge of 1mAh is exceeded, the data is reset to 1mAh.

RECORD MENU

1. Recording status icon
2. Reset recorded data
3. Interval of data recording
4. Recording time
5. Percentage of used storage

To make settings in the recording menu, press and hold K2. A small triangle points to the function you can set, you can then switch between the functions with K2 and select the functions with K1.
If the recording status icon lights red, the recording is interrupted, it lights green when it is recording.
The recording data can be reset under CE. The data recording interval can be set from 1-60 seconds, but only when the recording is paused and the recording time is reset. Press and hold K2 to exit the settings. If you switch off the device, the recording is interrupted.

QUICK CHARGE-RECOGNITION

The unit can automatically detect and display the current quick charge mode.

1. D+ signal voltage
2. D- signal voltage
3. Current charging mode

The following charging modes are supported: QC2.0, QC3.0, APPLE 2.4A/2.1A/1A/0.5A, Android DCP, Samsung.
Note that the values displayed are only references, not absolute values.

QUICK CHARGE PROTOCOL DETECTION

With this function, the device automatically detects which QuickCharge protocol is currently in use.
ATTENTION! This function increases the output voltage of the USB-C port.
Make sure that your connected load is compatible or remove it.
Keep K2 pressed, now “Dangerous” appears on the display.
With K1 you can start the detection. Supported protocols are displayed in green, unsupported protocols in red.
The following protocols can be detected automatically:
QC2.0, QC3.0, Huawei FCP, Huawei SCP, Samsung AFC and Type-C PD

PROTOCOL TRIGGER

This menu allows you to initiate a quick charge protocol even if your load does not have this quick charge function.
ATTENTION! This function increases the output voltage of the USB-C port.
Make sure that your connected load is compatible or remove it.
Keep K2 pressed to enter the menu.
With K2 you can navigate through the menu and with K1 into the submenus.
With K1 and K2 you can trigger the protocol and adjust the voltage.
Keep K2 pressed to get back.
