供貨商：Siri 白 行動電話： Accuracy Specifications ± (% of reading + % of range) 1 1. Specifications are for 90 minute warm-up and 100 PLC. 2. Relative to calibration standards. 3. 20% overrange on all ranges, except DCV 1000 V, ACV 750 V, DCI and ACI 3 A ranges. 4. For each additional volt over ± 500 V add 0.02 mV of error. 5. Specifications are for sinewave input > 0.3% of range and > 1 mVrms. Add 30 μV error for frequencies below 1 kHz. 750 VAC range limited to 8 x 10 7 Volts-Hz. For each additional volt over 300 Vrms add 0.7 mVrms of error. 6. Specifications are for 4-wire resistance measurements, or 2-wire using Math Null. Without Math Null, add 0.2 ? additional error in 2-wire resistance measurements. 7. Specifications are for sinewave input > 1% of range and > 10 μArms. Frequencies > 5 kHz are typical for 1 A and 3 A ranges. 8. Specifications are for 1-hour warm-up using Math Null. Additional errors may occur for non-film capacitors. 9. For total measurement accuracy, add temperature probe error 10. Accuracy specifications are for the voltage measured at the input terminals only. 1 mA test current is typical. Variation in the current source will create some variation in the voltage drop across a diode junction.
