5

Isolation voltage

Input/output:   2500V DC for 1 min

Input/power supply：2500V   for 1 min

Output/power supply：2500V   for 1 min

V

The double isolation part numbers, their   output and power supply are grounded together , there is only between the input and output   isolation voltage

6

Overload

2 x voltage span 1   sec. 10 for times with interval of 10 sec.

10 x current span   for 1 sec. 5 times with an interval of 300 sec (only for hole thru. parts)

The input outside the linear range will   result in poor accuracy
