.3 Electrical Specifications
In order to ensure the operation of this unit and accurate measurement, be
sure to observe the following notes.
･ This power supply is able to use in about 200 mA max. The current over than
that is unable to supply.
When need the power transitively, put the electrolytic capacitor in between
VCC and GND.
･ GND is common with its of the main unit and the grounding wire of the AC
power supply. Do not connect to the GND of the measurement line so that it is
insulated from the measurement circuit.
The rating of the open corrector switch is 35 V, 50 mA max. Use the relay or
the LED lamp of which the current would be less than 50 mA when the power
supply is 35 V or less and the switch is ON.
When using the relay, always put the diode for absorbing the counter
electromotive force.
