○
The output value is smaller than the estimated value.
･
Take the same precautionary steps as for the measured
value on the counter.
･
Make sure the 9094 OUTPUT CORD is fully connected.
･
Make sure you've selected the proper output mode (
REC
or MON ).
･
Make sure the previously selected output mode (current or
frequency) is not active.
･
Check that the input impedance of the connected
measuring instrument is at least 1 M
Ω
.
･
Check that the mode of the connected measuring
instrument is not an AC coupling, or that the filter
function is disabled.
○
The output value is larger than the estimated value.
･
Take the same precautionary steps as for the measured
value on the counter.
･
Check that you've selected the proper output mode (
REC
or MON ).
･
Check that the previously selected output mode (current
or frequency) is not active.
･
The output value would shift for approximately 10 ms in
case that that the power supply changes the battery to the
AC adapter during
MON
output on current measurement
on REC output on frequency measurement. (See Chapter
5: AC Adapter (Optional) )
○
The measured value fluctuates.
･
Check that the measured circuit is stable.
･
During voltage measurements, check that the test leads are
fully connected.
･
Check the waveform. Some special frequencies can't be
measured, such as those of inverters.
