2. Set 5V dc on the multifunction calibrator and turn the output on.
3. Set the time interval function on the counter, start rise edge, stop fall edge. Set 50 Ω
or 100 kΩ input impedance in the counter. If the counter is not equipped with this
function, use a single resistor with value 1 kΩ to 10 kΩ / 0.1 W connected in parallel
to the counter input.
4. Set time interval on 5320A display in ms.
5. The counter should indicate 0 ms. If not, reset the counter display.
6. Push the OPER button. The Calibrator generates a passive squarewave with
frequency 2/T.
7. Compare the counter reading with the 5320A preset time value.
8. Verify the Calibrator’s performance as listed in Table 6-10. Deviations should not
exceed the specified limits.
AC Voltage Calibration Verification (5320A/VLC Models Only)
1. Select the ac voltage calibration function on the Calibrator. Set the output frequency
to 55 Hz.
2. Connect a standard multimeter to the appropriate output terminals of the Calibrator
and select the ac voltage function. Set the appropriate parameters on the standard
multimeter to meet its best accuracy.
