How to find out BVIR history data records:
Up 9999 records can be storaged. Here's the way to have access to
the history data stored in BVIR.
Long press "HOLD" button up to 3 seconds, the following graghs
We can tell: It’s the group 512 resistance/voltage value, the
voltage is 3.8V, resistance is 56.2mΩ.
And press right/left arrow button you can see the next/previous
record. Press up/down arrow button you can see the next/previous
10th record. Press ADJ button less than 5s will delete current
record, press and hold ADJ button up to 5s will clear all the history
After a long time of usage, the BVIR may be not accurate as the
beginning, then it needs to be calibrated. We can use zero point
and full range point to calibrate BVIR.
Step 1: Zero point calibration Connect the two probes
together(short circuit) like the following picture:
