Introduction

• How an instrument gets calibrated.
• Traceability of the instrument being calibrated.

]]> Run 1: Calibration of Ammeter

• Types of instruments used in the circuit.
• Ranges of Test and Standard Ammeter
  • Range of Standard Ammeter must be greater than the Test Ammeter.
• Ammeters connected in series in the circuit.
• Formula for calculation of error
  • Error = Test Ammeter Reading (A_t) - Standard Ammeter Reading(A_s).
  .

]]> Run 2: Calibration of Voltmeter

• Types of instruments used in the circuit.
• Ranges of Test and Standard Voltmeter
  • Range of Standard Voltmeter must be greater than the Test Voltmeter.
• Voltmeters connected in parallel with the power supply.
• Formula for calculation of error
  • Error = Test Voltmeter Reading (V_t) - Standard Voltmeter Reading ( V_s).
