Measurement tolerances
Statement of accuracy in ± (% of reading + display error in counts (= number of smallest points)). The accuracy is
valid for one year at a temperature of +23 °C (± 5 °C), and at a relative humidity of less than 80%, non-condensing.
Only valid at previous calibration of the measuring input.

SMD test tweezers
4-wire measuring line
Alligator clip measuring line
Tolerance: ± (A x B) (reading accuracy in %)
A: Specified basic accuracy
B: Measuring cable tolerances
B(%) = 1 + (L x F x T)
L(m): Cable length
F(MHz): Test frequency
T: Cable type. "T" is 40 for a 5-wire cable; otherwise "T" is 4.
when measuring with basic accuracy the following conditions should be met:
1. Ambient temperature: 23°C ± 5°C < 80% RH
2. Test cable length: 0 m
3. Calibration performed with open and closed measuring input
4. D ≤ 0.1 for C or L measurements; Q ≤ 0.1 for R measurements
