HOW TO GENERATE A mA SIGNAL
Push the OUT push-button; the display will show:
Pushing
s
or
t
push-button select the "mA" output type.
Push the FUNC push-button; the display will show the following:
By this screen it is possible to select the maximum load applied to
the instrument during mA generation. Select the minimum range
encompassing the impedance of the instrument under test in order
to reduce the power consumption of the MEMOCAL.
When the load is unknown, select the 500
W
in order to assure the
maximum compatibility.
NOTE
: When the instrument operates without AC adapter, the first
range (100
W
) is limited to 50
W
maximum.
The other ranges have not additional limits.
Pushing
s
or
t
push-button select the desired output load and
push the FUNC push-button.
The display will show the following:
Where:
NON - RANGEABLE
allows to select a mA generation without scaling (with a read-out in
mA).
RNG(L)
allows to select a mA output with read-out scaling (the selection of
the value to be generated will be made in engineering unit and not
in mA).
RNG(
QUAD
)
allows to obtain a quadratic mA output with programmable read-out
scale in engineering units (the selection of the value to be generated
will be made in engineering unit and it will be linear while the
resulting output will be quadratic).
3.9.1 - NON RANGEABLE - mA generation without scaling
Pushing
s
or
t
push-button, select the NON RANGEABLE output
type.
Push the FUNC push-button.
The display will show:
Where:
OUT
indicates that the instrument is performing a generation.
20 mA show the selected range.
