* The digit error(less than 5digits) is added in measuring value.
a. Set the function and range of DUT to "Freq." and
“
20kHz
”
.
b. Supply "10.000 kHz" to DUT and check the reading value is in specification,
" 9.895 to 10.105".
c. Change the range to "200kHz".
d. Set the out put of Signal Generator to "100kHz" and check the reading
value of DUT is in the specification, "97.50 to 102.50"
