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 1kW 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.

8. For ACV inputs at frequencies of 50 or 60Hz (±10%), add the following to “% of Range” uncertainty: 100mV 0.25%, 1V

0.05%, 10V 0.13%, 100V 0.03%, 750V 0.015 (Model 2701 only).

9. Auto Zero off.

10. Sample count = 1024.

11. DETector:BANDwidth 300 with nPLC = 0.006 (2701 only).

12. Maximum useful limit with trigger delay = 175ms.

13. Includes measurement and binary data transfer out GPIB or ASCII data transfer for Ethernet and RS-232 (Reading Element only).
