How do you set a galvanometer to low sensitivity?
Set the galvanometer to low sensitivity by turning the galvanometer SENSITIVITY adjustment knob. (Turn the knob counter clockwise.) Set the measuring dials (Rs) to 1.9999. Observe the direction of the pointer deflection of the galvanometer by depressing momentarily the GA switch after depressing the BA switch.
How does a galvanometer work?
Electric current. A battery is connected in series with a resistor and the galvanometer. The galvanometer is thus wired to detect currents in the circuit. The direction of the current flow is indicated by the chalk marks indicating which terminal of the galvanometer is the positive one and which is the negative one.
How can a galvanometer measure current?
To measure current galvanometer should be connected in series with the circuit. A galvanometer is designed to typically measure current in microampere or milliampere range. However, for larger currents, a shunt resistance is used in parallel with the galvanometer to protect it from excessive current and to extend its range.
How to check if a galvanometer is deflected?
Observe the direction of the pointer deflection of the galvanometer by depressing momentarily the GA switch after depressing the BA switch. If the pointer of the galvanometer deflects the plus ( ) side, increase the value of Rs dial, if the pointer is deflected to the minus ( ) side, decrease Rs to make the indication to 0.
What temperature should a galvanometer be depressed?
PRECAUTIONS 18 to 25°C and where humidity is low. POWER SUPPLY, GA and BA to OFF. In measurement, be sure to depress GA switch after BA switch has been depressed. If this order is reversed, the galvanometer pointer will misleadingly deflect for the measuring dial operation inductance of the resistor under test when BA switch is depressed.
