[1]Specifications are for 1-hour warm-up at 100 PLC integration time, 3 Hz (Slow) ac filter, sinewave input.

[2]Relative to calibration standards.

[3]20% overrange on all AC ranges, except 300V and 3A ranges which have 1% overrange.

[4]Values in the AC Characteristics Accuracy Specifications table are for sinewave inputs >5% of range (>15% of range for 300 VAC). For smaller inputs, add an additional error to the value in the table as follows:

		Additional Error Specifications to % Range Table Value for Sinewave Inputs:
		1% to 5% of range		3% to 15% of range

[5]300Vac range limited to 50kHz. For frequencies >50 kHz, signals must be <1.5 x 107 Volt-Hz.

[6]For frequencies below 100Hz, 3Hz (Slow) AC filter specified for sinewave input only.

[7]For 1kΩ unbalance in LO lead.

[8]Maximum reading rates for 0.01% of ac step additional error. Additional settling delay required when input dc level varies.

[9]For External Trigger or remote operation using default settling delay (Delay Auto).

[10]Maximum useful limit with default settling delays defeated.

[11]Speeds are for 0.02 PLC integration time, Delay 0, and 200Hz (Fast) ac filter.

[12]100Vac and 300Vac ranges may latch up the module or system mainframe if you drive the LO terminal with a high voltage, high frequency input. Only drive the HI terminal when measuring ac voltages.
