Chapter 2 Measurement Procedure

NOTE
･
REC
outputs are analog outputs. The output
response time during a f.s. input differs between rise
(0% to 90%, about 250 ms) and fall (100% to 10%,
about 500 ms). (Figs 2 and 3) As the measured
value is small to the range response time becomes
long.
･ Changes of counter updating rate, peak
measurement, frequency measurement, recording,
and data holding are possible when generating
current measurement output. (But output will be
changed during mode shift, range shift, shift to
voltage measurement mode, or auto-zero-
adjustment.)
･ Use the optional 9094 OUTPUT CORD to connect
the unit to a recorder.
･ For recorders, use over 1 MΩ input impedance.
Low impedances will affect indicated values.
･ Even if you press while recording frequency
measurements, output is still for the frequency. To
obtain a current output, press
OUTPUT
to disable
the frequency output, then make new settings.
･ For a long term measurement, use the optional
9445-02 or 9445-03 AC ADAPTER.
･ When the AC adapter is used and there is a large
amount of noise in the power line, the display may
show several counts or noise may be present in the
output. In such a case, connect the ground terminal
of the level recorder or the L side of the input to
ground.
