Page 13: V.the Use Of Discharge Rod
FIG. 20 Booster interface of automatic withstand voltage test When the voltage rises to the set voltage, start the timing, and the instrument will turn off the high voltage when the timing is finished. Automatic discharge. Figure 8 shows the automatic discharge screen.If the discharge voltage is very slow, it is recommended to use a discharge rod for manual discharge. -
Page 14: Vi.precautions
2. Pay special attention not to discharge the ground wire directly on the high-voltage microammeter housing, so as to avoid the damage of high-voltage microammeter caused by the strong impulse discharge current VI.Precautions 1.Boost before: to boost the knob "zero", and then press the high voltage through the boost experiment.
