Input impedance 1 M
Ω
±4%, 100 pF or less
Crest factor 3 or less
(For the 1000.0 V range, 1.5 or less for 100% of the
input of the range, 3 or less for 50% of the input of
the range)
Auto range The range moves depending on the DC+AC
calculation result.
Accuracy guarantee
range
5% or more of each range (less than 5% of each
range is outside of the guaranteed accuracy)
With the lter ON, the accuracy is specied in
100 Hz or less. Furthermore, 2% rdg. is added.
Frequency range: 20 Hz to 100 kHz (A measured
values outside of the accuracy guarantee range for
frequency is also displayed.)
Accuracy of DCV (main display) and ACV (sub display) when SHIFT is
pressed during DC+ACV measurement
1. DCV (main display): the accuracy of 45 Hz to 65 Hz in the accuracy
table is applied. Note however that 2%rdg. should be added when there
is AC voltage superimposition less than 45 Hz.
2. ACV (sub display): according to the accuracy table
