600.0 V "LoZ"
600.0 V "Motor" **
* only available via the measuring function "mV"
** the precision indicated is not valid for speed-controlled motor drives
Frequency range 40 - 400 Hz; Overload protection 750 V; Impedance: 10 MΩ (mV: ≥100 MΩ)
Specified measurement range: 5 - 100 % of the measuring range
When the measuring input is short-circuited, a display of 5 counts is possible
After use of the LoZ function, a regeneration time of 1 minute is required
TrueRMS crest factor (CF) ≤3 CF to 600 V, ≤1.5 CF to 750 V
TrueRMS crest factor for non-sine-shaped signals plus tolerance addition:
CF >1.0 - 2.0 + 3%
CF >2.0 - 2.5 + 5%
CF >2.5 - 3.0 + 7%
Criteria for phase recognition variable frequency in the "motor" mode: >80 V/AC, from 50 to 80 Hz
