Performance Verification

22

Test 6. Bandwidth Check (100 mV/A range)

29

Increase the generated frequency to 100 kHz.

30

Measure the current in the coil (

I

c

) and record the current reading 

in 

Table 11

.

NOTE

The current in the coil must be 

¡

 10 mA.  Increase the generated amplitude if 

necessary to achieve a current of at least 10 mA.

31

Measure the voltage output (

V

PROBE

) by the probe on DMM 2, and 

record in 

Table 11

.

32

Do the calculations specified in 

Table 11

 to determine if the probe 

passes the test.
