Notes:
[1] Continuous current more than DC 7A or AC RMS 7A should be 30 seconds ON and 30 seconds
OFF;
[2] Each additional volt over ± 500 VDC adds 0.02 mV of error;
[3] Errors in above table are corresponding to 2-wire resistance function in math Null. Without Math
Null, the error is ± 0.2 Ω additional errors in 2–wire resistance function;
[4] The reading resolution of multimeter is 5½ ;
[5] Q: Optional quick test point.
