This procedure describes the calibration of the Audio Frequency Impedance Measuring Equipment, OJ-1, OJ-2, OJ-3, or GR 650A, herein referred to as the Test Instrument.nThis procedure will verify correct performance of the Test Instrument within the required tolerances. Normally, each recorded value will be compared to its tolerance and corrective action taken, if required, before continuing the test. However, it is sometimes desirable to delay the verifi¬cation and corrective action until several related values have been recorded. Perform corrective action in accordance with the instruction manual and local laboratory practices. All data must be recorded on the Calibration Report form.nRead the entire procedure before starting the calibra¬tion.
