4.5 Calibration Loop
The provided 5Ω calibration test loop (Figure 4-2) lets you perform a quick check
of the instrument’s accuracy. To do this, turn ON the instrument and wait until
it completes its startup calibration cycle. Then clamp the instrument around
the loop; the measurement should read between 4.8Ω and 5.2Ω. If not, clean
the instrument and repeat the measurement. If you are still unable to obtain a
measurement between 4.8Ω and 5.2Ω, contact AEMC.
