1. Reading speeds for 60 Hz (and 50 Hz) operation, autozero off, xed range.
2. Add 5 nA for the 100 µA range, add 0.2 µA for the 10 mA range.
3. Add 20 µV for DCV and 20 mΩ for resistance. Add 0.2 µA for DC current + 10x the above range error for the 10 mA range. For 0.2 PLC multiply the above
range error by 5x on the 1 A and 10 A ranges, and by 10x for the 10 mA range.
4. Maximum reading rates for 0.01% of AC step additional error. Additional settling delay required when input DC level varies.
5. For external trigger or remote operation using default settling delay (Delay Auto).
6. Maximum useful limit with default settling delays defeated.

1. For DCV on the 10 V range with zero volts input and auto zero on.
2. RMS noise adder for both the 34465 and the 34470. Measured with zero volts input and auto zero on.
3. The following DCI ranges have these additional multipliers: The 10 mA by 5x, the 100 mA by 2x, and the 10 A by 1.6x.
4. Requires the digitizing option (Option DIG).
