Frequency verification
To verify the Model DMM7510 frequency function:
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.
4. On the Model DMM7510, press the
FUNCTION
key, select the
Measure Functions
tab, and
select
Frequency
.
5. Select the
MENU
key.
6. Select Measure
Settings
.
7. Set the Aperture to
250 ms
.
8. Set the Threshold Range to
10 V
.
9. Set the Threshold Level to
0 V
.
10. Press the
HOME
key.
11. Source the voltage and frequency values as listed in
(on page 2-33). For
each setting, be sure that the reading is within low and high limits.
