[1] Specifications are for 90-minute warm-up, slow ac filter and sinewave input.
[2] 10% overrange on all ranges except ACV 750 V and ACI 10 A ranges.
[3] Relative to calibration standards.
[4] Specifications are for sinewave input >5% of range. For inputs within 1% and 5% of range and <50 kHz, add 0.1% of range additional error. For
50kHz to 100kHz, add 0.13% of range additional error.
[5] ACV 750 range limited to 8x10

Volt-Hz. For input over 300V rms, add 0.7mV error for each additional volt.
[6] For continuous current > DC 7A or AC RMS 7A, 30 seconds ON and 30 seconds OFF.
[7] For frequency blow 100 Hz, the specification of slow filter is only for sinewave input.
[8] Specifications are for sinewave input >5% of range. For inputs within 1% to 5% of range, add 0.1% of range additional error. Specifications are typical
values for 200uA and 2mA, 2A and 10A ranges when frequency >1kHz.
