The above mentioned measurement deviations relate to the following data:
•
ambient temperature of 18 °C to 28 °C
•
relative humidity between 20 % and 75 %
•
wire centred and parallel to the marking on the clamp
•
sinus signal form for AC measurement
•
impedance of the connected measuring device >100 k Ohm
•
battery voltage 8 V
DC
•
the operational condition of the clamp one minute after it was switched
on.
