Chapter 5 Specification The general and measurement precision specification of LCR are described below. 5.1 General Specification 5.2 Accuracy Notes: Environment temperature: 20 ℃ ± 2 ℃ , humidity: ≤75% R.H; Preheat the instrument for at least 30 minutes before the test; Test at the test notch on the end face of the instrument; It is better to conduct open and short circuit correction before the test; Measure with the recommended equivalent mode; The percentage in terms of error indicates:
± (% of the reading + last digit) If the actual measurement of the instrument and the display exceeds the scope specified in the table, the accuracy of the excessive part will not be given; The meaning of the subscript S- series equivalent; p- parallel equivalent; e- accuracy Some parameters cannot be given in the data table, and it can only be calculated based on the measurement results; 23 Model Hantek1832C Hantek1833C Measurement parameters Main parameter: L/C/R/Z Secondary parameter:
