Notes:

1) ‘Burden Voltage’ is the voltage drop across the meter when measuring a current. Burden voltage is specified for a given input current – In this

case the maximum rated current at the highest measurement range.

2) Exceeding Absolute Maximum ratings may result in permanent damage to the meter.
