possible. 

Self provided Kelvin fixture: purchase instructions, BNC male pin, regular 

manufacturer standard head. Otherwise, the main hole will be damaged greatly and 
the contact will be poor, which will affect the measurement accuracy and accuracy.

Anti-interference 

When the frequency value is an integer multiple of the power frequency (50 

/ 60Hz), the measured value is superior to other frequency points. In the disturbed 
environment, the even multiple of the power frequency is better than the odd 
multiple of the frequency. That is to say: the measured value of odd frequency 
multiplication point is more susceptible to environmental interference. Even if 
the system has done anti-interference related processing, it cannot be completely 
shielded  when  the  interference  is  large.  (Please  refer  to  the  previous 
"Interference Degree" for the size of environmental interference)

Safety requirements 

1

Charge 

This unit is not equipped with a charger. Please use a 5V charger for mobile 

phones or tablet computers with a current of more than 1a.After the product battery 

is low, please charge it in time to avoid damaging the battery. 

In addition, the electric quantity indication of the product is schematic, 

especially when charging, the error will be relatively obvious. In this case, 

as long as the error is not very large (about 15%), it is normal, not the product 

or battery is damaged, please know. 

2

Storage 

Since the product contains a lithium polymer battery, please turn off the 

product and store it when fully charged. If it is not used for a long time, it 

is recommended to charge it every 3 months to avoid battery damage due to lack 

of power. 

This charging port uses a USB socket, but it is not a USB communication 

interface. At the same time, connecting the USB port of the computer will produce 

interference signals, affecting the normal operation of the product.
