Calibration
DMM7510-905-01 Rev. A / April 2015 3-19
AC frequency adjustment step 18
1. Connect the Keysight Technologies 33250A function generator to the Model DMM7510 INPUT HI
and LO terminals, as shown in the following figure.
2. Set the function generator output impedance to High, amplitude of 5 V
RMS
, waveform to
square wave.
3. Enable the output.
cal.ac.adjust step 18 requires the source frequency value to be entered. The AC adjust step 18
supports an allowed range of source frequencies from 900 Hz to 1.1 kHz.
4. Send the following command:
cal.adjust.ac(18, 1000) -- 1V, 1kHz HI and LO Ft terminals. Enter AFG frequency
value.
Set time and calibration adjustment dates
Use the following commands to set the Model DMM7510 time and adjust date.
localnode.settime(2015, 01, 09, 10, 04, 38) -- (year, month, date, hour, minutes,
sec)
cal.adjust.date = os.time({year=2015, month=01,day =09})
print(os.date("%m/%d/%Y", cal.verifydate))
