1) See the typical curve of the 300Hz.
2) This range is accessible only with the Range key
Input impedance: approx. 10.6M
Ω // 50 pF
3) The LCD indicates “+OL” above +1050V, “-OL” below -1050V or above 1050VRMS.
4) From 1kHz, the measurement must exceed 15% of the range.
Secondary measurements and displays: FREQ (AC coupling), MAX, MIN, AVG, PEAK
VLowZ AC RMS The pass band (between 3dB down points) is reduced to 300Hz, if the filter is activated. In
VLowZ, there is no 60mV range.
The frequency measurement is made like the measurement in a 300Hz pass band.
Protection: 1414 Vpk
