AC Notes
1.20 % overrange except on 750V and 3A.
2.Specification are for SLOW mode and sine wave inputs >5% of range. SLOW and MED are multi-sample A/D conversions. FAST is DETector:BANDwidth
300 with nPLC = 1.0.
3.Applies to 0°–18°C and 28°–50°C.
4.For square wave inputs >10% of ACV range, except 100mV range. 100mV range frequency must be >10Hz if input is <20mV.
5.Applies to non-sine waves >5Hz.
6.For 1kΩ unbalance in LO lead.
7.Speeds are for 60Hz (50Hz) operation using factory defaults operating conditions (*RST). Autorange off, Display off, Limits off, Trigger delay=0. Includes
