Resistance values in orms ( ).
V: Voltmeter or oscilloscope
(r.m.s. or peak reading)
Input resistance :
Input capacitance :
Frequency range : 15 Hz to 1 MHz and d.c. respectively
Note: Appropriate measures should be taken to obtain the correct value in case of non sinusoidal
waveforms.
The measuring instrument is calibrated by comparing the frequency factor of
figure F.2 of IEC 60990 at various frequencies. A calibration curve is constructed showing the
deviation of

The part or contact of a TERMINAL is not HAZARDOUS LIVE if:
a) The open-circuit voltage should not exceed 35 V (peak) a.c. or 60 V d.c. or, if a) is not met.
b) The measurement of the TOUCH CURRENT shall be carried out in accordance with IEC 60990,
with the measuring network described in Annex D of this standard.
