| UNI-T UT211B upper amp range not work |
| (1/1) |

Hello, people! This is my first post on this beautiful forum. Hope to have a useful time here! On the problem.. I have UNI-T UT211B clamp meter. After a time, when I needed to measure amperage on 60A DC range I found out that meter don't show reading on display. On 60A AC too. Shows only zeroes. Only low range 6000/600 mA works. I don't see any problem on the board, when checked. Here she is: IMG_20221004_104725960.jpg (1158.65 kB. 2113x1189 - viewed 37 times.) The only thing that comes to my mind is corrupt EEPROM. I will be very, very happy if someone share his dump file of his UT221B! Have a programmer to do the job. Thank you in advance, people! |

In fact, after self-calibration, it turned out that the DC reads the current at 60A. Only at 60A AC range does not read and at NCV range does not make a sound when touching the power cable. I found these problems after Duracell battery leak. But it was a little drop on the back of the board. May be I'm missing something wrong on the board and thing is a EEPROM? |
