Practical - 7 :- Measure the voltages of the given cells/battery using analog/digital multimeter

Measure the voltages of the given cells/battery using analog/digital multimeter 

Objectives: At the end of this exercise you shall be able to

• Measure the voltage of given cell/battery using analog multimeter 
• Measure the voltage of given cell/battery using digital multimeter.

Requirements Tools/Equipment's/Instruments

• Digital multi meter with probes - 1 No
• Analog multi meter with probes- 1 No

Materials/Components

• Lead acid battery 6V/12V any AH rating  - 1 No
• 1.5V/3V/9V battery -1 No each

PROCEDURE 

TASK 1 : Measurement of cell/battery voltage using analog multimeter

1. Observe the front panel and insert the black colour probe “COM” socket of analog multimeter and insert the red colour probe into the V mA : socket as shown in Fig 1

2. Set the range selector knob of multimeter to DCV, as shown in Fig 2. 

3. Set the voltage range nearest to the cell / battery voltage as shown in Fig 3.

4. Pick the 9V battery, place the black probe on the negative (-) terminal and red probe on the positive (+) terminal of the battery as shown in Fig 4.
5. Check the Analog voltmeter reading as shown in Fig 5 and record the reading in Table 1. 6 Repeat step 4 and 5 for the remaining labelled cells/ battery. 7 Get the work checked by the Instructor
