Introduction
♦ The Charge Sensor can be used to measure electric quantity of a conductor. For example: it can be used to replace traditional gold leaf electroscope and electrometer in static electricity experiment. It designed with alligator clip which covered by plastic. The wires used are red and black (for ground). There is a button equipped on the sensor which is used to change the measuring range. Press the button and the measuring range will become high otherwise it will be low. There is a reset button equipped on the sensor which is used to discharge the capacitor.
Usage
♦ Connect alligator clips to Charge Sensor. Connect Charge Sensor to datalogger. Select proper measuring range.
♦ The internal resistor designed in Charge Sensor is extremely high. It will gain charge from the surrounding environment. Press the reset button before experiment. Press it again to discharge the sensor after collecting.
♦ In order to eliminate the effect from static electric field, ground the sensor during using. If it can not be grounded, user should stand on ground and keep still. For those experiment which need high precision charge measuring, fix the sensor to ensure the result is accurate. Be careful of effect from weather during using. The air humidity can also affect the accuracy of data measuring. Dry the surrounding air to ensure the accuracy.
Notes
♦ The wire used to connect alligator clips to sensor must be covered by plastic.
♦ Discharge the built-in capacitor before any experiment. Short connect red and black alligator clips or press reset button.
♦ For those experiment which need high precision charge measuring, fix the sensor to ensure the result is accurate.
♦ The air humidity can also affect the accuracy of data measuring. Dry the surrounding air to ensure the accuracy.
