The multimeter AC/DC automatic conversion circuit is shown below:
The ordinary digital multimeter can be used to complete the AC and DC measurement conversion by manual operation. The new DT860D digital multimeter (multimeter is also called multimeter, three-meter, multiplexer, multimeter is divided into pointer multimeter and digital multimeter. It is a multi-function, multi-range measuring instrument, the general multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, etc., some can also measure AC current, capacitance, inductance and some parameters of semiconductor (such as β).) Use NJU9207F automatic range conversion chip with peripheral The auxiliary circuit implements an AC-DC (AC/DC) automatic conversion measurement function.
A manual pulse generator (MPG) is a device normally associated with computer numerically controlled machinery or other devices involved in positioning. It usually consists of a rotating knob that generates electrical pulses that are sent to an equipment controller. The controller will then move the piece of equipment a predetermined distance for each pulse.
The CNC handheld controller MPG Pendant with x1, x10, x100 selectable. It is equipped with our popular machined MPG unit, 4,5,6 axis and scale selector, emergency stop and reset button.
