[Test-Equipment] Should I Import this ESR Meter?

[Brooke Clarke]

Hi:

The manual is now in Russian and I'm thinking how to make the machine 
translation better or completely rewrite it.

No.  There is a pair of anti-parallel diodes across the input to shunt 
out low voltages.  The meter is designed for testing caps in circuit 
when the power if off and the caps are discharged.  The key function of 
an ESR meter is to identify caps where the electrolyte is no longer 
working properly which leads to higher peak voltages and hum on the DC.  
That this meter also can measure capacitance is a secondary function.

The ZM-11 will test caps at up to 500 V.
