Are you talking about the 2001712003? Please try to hold the bottom button 6 seconds, then calibration values will be reset back to the factory settings
I am using 3 of the 2001712003 meters to monitor voltage and current of motors running under a load. The load is adjusted on the motors for a current draw of 3.3A. My issue is that 2 of the meters will only read the final digit of the current in even numbers. ie 3.2, 3.4. The 3rd meter only reads the final digit in odd numbers. What am I doing wrong?
