4 Specifications
Table 4-3 Frequency accuracy ± (% of reading + count)
Function
100.000 mV to 750.00 V
Frequency
[1] The specifications are using an aperture of 1 second. The frequency can be measured up to 1 MHz as 0.5 V signal to 100 mV
or 1 V ranges.
[2] 10% of range to full scale input on all ranges except where noted. 100 mV range specifications are for full scale or greater
inputs. For inputs from 10 mV to 100 mV, multiply total % of reading error by 10
[3] 10% of range to full scale input on all ranges except where noted. 10 mA range specifications are for full scale or greater
inputs. For inputs from 1 mA to 10 mA, multiply total % of reading error by 10
