we adjust the appearance of TC66C, make it easier to understand how to put the switch(power supply switch and PD switch)
“Power supply switch button. When on, you can use system power supply; when off, you can use isolated power supply. For high precision and lower voltage measurement, you can switch to OFF and use micro port to power on.
PD Switch, place the switch on ”OFF” when measuring a device which is charging, PD function OFF; and place the switch on “ON” when do decoy trigger operation, PD function ON. Switch stroke is short so use the switch gently to avoid damage please.”
