b)
When the electric shock protection is set to FLOAT, the high-voltage output high terminal HV1,
low terminal HV2 are in a float state, as shown in Figure 4-6. When the human body
accidentally touches the test high voltage terminal, the low terminal HV2 of the high voltage
circuit is not grounded ,but isolated from the ground, equivalent to connecting a high insulation
resistance, therefore, the current through the human body will not exceed 3 mA, thus ensuring
the safety of operator. As shown in Figure 4-7.
