Chauvin Arnoux F405 - AC Voltage Measurement Characteristics

35
Note (1) - The display indicates "+OL" above +2000V and "-OL" below – 2000V in
REL mode
- Above 1000V, a repetitive beep indicates that the voltage being
measured is greater than the safety voltage for which the device is
guaranteed.

Note (1) - The display indicates "OL" above 1400V (in PEAK mode).
- Above 1000V, 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 "----" on the display.
