Accuracy Table
Input impedance 1 M
Ω
±4%, 100 pF or less
Crest factor 3 or less
(For the 60.000 mV/ 600.00 mV/ 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)
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
value outside of the accuracy guarantee range for
frequency is also displayed.)
DC superimposition • For the superimposition on 200 V DC or less, see
the accuracy table.
• For the superimposition on over 200 V DC
to 500 V DC or less, 2% rdg. is added to the
accuracy specication in 1 kHz or less.
• For the superimposition on over 500 V DC, 10%
rdg. is added to the accuracy specication in
1 kHz or less.

*1: After leaving the instrument in an environment where the ambient air
temperature has been stable for at least 30 minutes, allow the input to short
circuit and activate the relative value display function (REL). The accuracy is
then specied. After activating the REL, the temperature uctuates within ±5°C.
