same. 2. Operating instructions (1) Zeroing—Turn the measuring knob to “OFF”(关) first, adjust the mechanical zero setter(0) in the instrument's center, to make the pointer locate on zero line(0). Caution: --This process should be adjusted carefully before connecting power supply, so as to ensure the accuracy rate.

a. when in use(especially measuring 10~100mT), if the probe is pressed, distorted or temperature on the magnets to be measured changes, the zeroing process should be performed to eliminate errors. b. Due to the high sensitivity of 10mT measuring range, tester should check frequently if the zero line”0” changes? If so, zeroing process should be performed before measuring.
