Note (1) Above 1000V (RMS), a repetitive beep indicates that the voltage
being measured is greater than the safety voltage for which the
device is guaranteed. The display indicates "OL".
- Bandwidth in AC = 3 kHz
Note (2) Any value between zero and the min. threshold of the measurement
range (0.15V) is forced to show "----" on the display.
Specific Specifications in MAX/MIN mode (from 10Hz to 1kHz, and from
0.30V in AC):

Accuracy: add 1% R to the values of the table above.

Capture of the extreme: approximately 100ms.

Note (1) The display indicates "OL" above 1000V (1400V in PEAK mode).
Above 1000V (DC or RMS), a repetitive beep indicates that the
voltage being measured is greater than the safety voltage for which
the device is guaranteed.
- Bandwidth in AC = 3 kHz
