1.  Input impedance: Refer to Table A on page 10.
2.  ACV measurement is AC coupled; while ACmV and AC μA/mA/A measurement are DC coupled. All
specifications are valid from 5% to 100% of range. The crest factor may be up to 3 at full scale, up to
5 at half-scale, except for 1000 mV and 1000 V ranges, where the crest factor is 1.5 at full scale and 3
at half scale.
3.  Input current >35 µARMS.
4.  Current can be measured from 2.5 A up to 10 A continuously. An additional 0.5% needs to be added to
the specified accuracy if the signal measured is in the range of 10 A ~ 20 A for 30 seconds maximum.
After measuring a current of >10 A, leave the meter to cool down for twice the measuring time used
before application of low current measurement.
5.  Input current < 3 ARMS.
6.  These specifications are for typical performance.
7.  Crest factor ≤ 3.0 at full scale, 5.0 at half scale except the 1000 mV and 1000 V ranges where it is
1.5 at full scale, 3.0 at half scale. For non-sinusoidal waveform, add 0.1 % of reading ± 0.3 % of range.
8.  Additional error to be added for frequency > 15 kHz and signal input < 10 % of range: 3 counts of LSD per kHz.
9.  2% over-range on all ranges except AC 1000 V range
