@HKJ Can you dump the EEPROM of the Zeast 282 and post it here? I wonder if that can be used to enable the REL button.
Hi,guys!
EEPROM of the Hy-19E(Zeast 282) it is possible to download at this link https://yadi.sk/d/fy7nRoX_3Lqzsf. This dump became available thanks to the review on a multimeter from the user of uncle_sem at the Russian-speaking forum https://mysku.ru/blog/china-stores/54451.html
There are two positions seems may modify something base on my web search (base on other DTM0660 models and not tested!):
1. 10H, 11H data corresponds to the division value 10000, 12H, 13H corresponds to the shift upper limit of 9200, 13H, 14H corresponds to the shift off line 880(UT139B)
2. Description of the address in the form:
24H, 25H is the NCV base (threshold, threshold), that is, the mV value that has an initial response to the start of the mains induction.
26H, 27H for NCV resolution, in general, for UT139C is the first short bar of the display to the second short bar (second to third, third to fourth) display required The mV value is the mV value required for the first display light to be displayed after the first display light is displayed.
You can adjust the NCV starting sensitivity by changing the address 24H value, increase the sensitivity and increase the sensitivity.
The numerical choice is generally:
28, 32, 64, 96, FA
Specific model reference value: UT139C, the value is FA, UT139B is FA, UT210E is 64, and UT211B is 96.
sorry for my bad English
