*. Set the Function and range of DUT to "AC A" and
“
2mA
”
.
1. Set the out put of Meter calibrator to "1mA 50Hz" and connect to
“
mA
’
terminal.
2. Check the reading value of DUT is in the specification," 0.9840 to 1.0160"
3. Change the out put of Meter calibrator to
“
1mA 60Hz
”
and check the reading
value of DUT is in the specification, " 0.9915 to 1.0085"
4. Change the out put of Meter calibrator to
“
1mA 1kHz
”
and check the reading
value of DUT is in the specification, " 0.9790 to 1.0210"
5. Change the out put of Meter calibrator to
“
1mA 5kHz
”
and check the reading
value of DUT is in the specification, " 0.9690 to 1.0310"
*. Change the range to "20mA".
1. Change the out put of Meter calibrator to
“
10mA 50Hz
”
and check the reading
value of DUT is in the specification, " 9.840 to 10.160"
2. Set the out put of Meter calibrator to "10mA 60Hz" and check the reading
value of DUT is in the specification, " 9.915 to 10.085"
3. Change the out put of Meter calibrator to
“
10mA 1kHz
”
and check the reading
value of DUT is in the specification, " 9.790 to 10.210"
4. Change the out put of Meter calibrator to
“
10mA 5kHz
”
and check the reading
value of DUT is in the specification, " 9.690 to 10.310"
*. Change the range to "200mA".
1. Set the out put of Meter calibrator to "100mA 50Hz" and check the reading
value of DUT is in the specification, " 98.40 to 101.60"
2. Set the out put of Meter calibrator to "100mA 60Hz" and check the reading
value of DUT is in the specification, " 99.15 to 100.85"
3. Set the out put of Meter calibrator to "100mA 1kHz" and check the reading
value of DUT is in the specification, " 97.90 to 102.10"
4. Set the out put of Meter calibrator to "100mA 5kHz" and check the reading
value of DUT is in the specification, " 96.90 to 103.10"
