Student Meter/EDUCATION METER MODEL /teaching instrument
Voltmeter and Ammeter with together.
DC Ammeter-Voltmeter is suiable in middle schools for students to mecasure the currend and the vltage in the eircuil. Structure:Mainly consistsof a shell & a meter.There are 9 terminals on the shell. Four terminals in the left is for Ampere. four terminals in the right i for voltage. One terminal at the down side is the negative pole for both Ampeter & Voltage.
1.Indicating panel is in the water level.
2.The ambient temperature at work is from 0c-40c and the relatuve humidity<=85%.
