4 / 10 page Input Speciications The accuracy is given as ± (% of reading + counts of least signiicant digit (LSD)) at 23 °C ± 5 °C, with relative humidity less than 80% R.H. and after a warm-up period of at least ive minutes. Without warm-up, an additional ive counts of LSD need to be considered.

Input impedance: 10 MΩ (nominal) for the range of 5 V and above, and 1 GΩ (nominal) for the 50/500 mV range. 2. Accuracy can be improved to 0.05% + 5. Always use the Relative function to offset thermal effects before measuring the signal. 3. Input impedance: 1.1 MΩ in parallel with < 100 pF (nominal) for the range of 5 V and above, and 1 GΩ (nominal) for the 50/500 mV range. Crest factor ≤ 3.

Always use the Relative function to offset thermal effects before measuring the signal. If this function is not used, accuracy could go down to 0.03% + 25. Thermal effects may be present due to: – Constant current, constant voltage, or square wave output. – Wrong operation. For example, resistance, diode, or mV measurement function is used to measure high voltage signals exceeding 250 V. – After battery charging has completed. – After measuring current greater than 50 mA. 2.
