Current sensitivity:Pointer from zero scale to maximum scale (full scale position) Sensitivity 250 uA 10 % Internal impedance: 650 10 %. Insulation resistance: 500V DC plus 50M ohm or more for the outer box of the meter and the electrical circuit. The insulation resistance of the meter housing and the electrical circuit is tested by 500V DC voltage. Zero position: the standard position of the meter is used, and the point where the front of the pointer and the center of the zero scale are unified is the reference pointer and the zero scale overlap. The tolerance is 1mm. Balance: The allowable error range of the meter when the standard position is tilted 90 degrees forward and backward is 1mm. The pointer sticks: When the full-scale current triples the overcurrent in an instant and slowly reduces
