Hi,
I have this EVB v1.1 esr meter which I bought online from portugal. I have not used it for quite some time. Now it is showing a reading of 1.4 ohms, no matter which capacitor I check. According to the catalogue, you have to short both the probes while pressing the ON button to clear it to zero. I tried this but when I release the ON button, the reading shows the same 1.4 ohms. Shorting both terminals shows the same 1.4 ohms. There are 2 trimpots on the meter. How do I reset or calibrate it to read zero.
Thanks
