Technical Data
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
± 0.5 V
• the operational condition of the clamp one minute after it was switched
on.
