What are the key points to be considered while choosing a suitable model?
1. What are the objects to be measured? Models to be chosen differ depending on what you intend to measure, AC current, DC current or Leakage current. 2. Measurable conductor sizes: A wide range of sizes are available from 21mm to 53mm in diameter according to measurable conductor sizes and measuring places. 3. Is true RMS measurement required? A clamp meter of the mean-value type cannot provide accurate results in the measurement of an inverter circuit and a motor circuit having many distortions. To make measurements for such circuits, a clamp meter of the true RMS type is required. 4. Other functions: Other types are available featuring a tester function and recorder output function in addition to current measurement.

1. What are the necessary measuring functions? Choose the necessary functions, except voltage and resistance measurements. (including need for the measurement of current – 400mA, 10A, 12A, 20A, capacitor, frequency, temperature and measurement of 4-20mA, etc.) 2. Other necessary functions: Functions required differ depending on where the measurement is taken A) To record measured valued concurrently with the process of measurement * To fix data by the data hold function * To secure the test lead in the holster B) To check changes in measured values * Measurement of maximum values, minimum values, and relative values 3. For measurements of waveforms of non-sine waves, choose a model supporting measurements by RMS values: In measuring distorted sine and non-sine waves (square waves, triangular waves, pulse), significant errors occur in measurements by mean values. There are two types of RMS values: AC-coupled true RMS value: Adapted to measurements of distorted sine and non-sine waves of
