11 / 20 page 11 | Keysight | U1450A/U1460A Insulation Resistance Testers - Data Sheet U1453A/U1461A adjustable DC test voltage speciications Adjusted DC test voltage specifications with accuracy of ± (% of reading + number of least significant digit)1, 2 Range Resolution Accuracy Rate current 1100 V 1 V 0.5% + 1 1 mA nominal 1. The minimum test voltage may be set from 10 V 2. The indication at the rated output voltage across a resistor with a value of UN × (1000 Ω/V) shall not differ by more than 10% relative to the indi- cated value, as a result of possibly present AC voltage components in the output voltage, when a capacitor of 1 µF is connected in parallel with the insulation resistance to be measured U1451A/U1452A/U1452AT DC voltage speciications DC voltage specifications with accuracy of ± (% of reading + number of least significant digit) Accuracy Function Range Resolution U1451A U1452A/U1452AT Input impedance Voltage1 6 V 0.001 V 0.5% + 2 0.2% + 2 10 MΩ (nominal) 60 V 0.01 V 0.5% + 2 0.2% + 2 10 MΩ (nominal) 600 V 0.1 V 0.5% + 2 0.2% + 2 10 MΩ (nominal) 1000 V 1 V 0.5% + 2 0.2% + 2 10 MΩ (nominal) 1. DC V overload protection: 1000 V RMS U1453A/U1461A DC voltage speciications DC voltage specifications with accuracy of ± (% of reading + number of least significant digit) Function Range Resolution Accuracy Input impedance Voltage 60 mV1 0.01 mV 0.09% + 1 10 MΩ3 600 mV1 0.1 mV 0.09% + 1 10 MΩ3 6 V2 0.001 V 0.09% + 1 11.11 MΩ 60 V2 0.01 V 0.09% + 1 10.1 MΩ 600 V2 0.1 V 0.09% + 1 10 MΩ 1000 V2 1 V 0.09% + 1 10 MΩ 1. The following statements are true for DC mV measurements: – DC mV measurements are for model U1461A only – The accuracy is speciied after the Null function is used to subtract the thermal effect (by shorting the test leads) – DC mV overload protection: 1000 VRMS for short circuits with < 0.3 A current 2. DC V overload protection: 1000 VRMS 3. The input impedance may be set to > 1 GΩ in the Setup menu U1451A/U1452A/U1452AT AC voltage speciications AC voltage specifications with accuracy of ± (% of reading + number of least significant digit) Accuracy Function Range Resolution 45 to 400 Hz Voltage1 6 V 0.001 V 2.0% + 3 60 V 0.01 V 2.0% + 3 600 V 0.1 V 2.0% + 3 1000 V 1 V 2.0% + 3 1.
