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.
