An analogue measuring instrument
can be connected (Ri = 10km)
which is used to monitor:
0
—
10V tor 0 + 60HZ
or 0
—
10V tor 0
—
120Hz
Adjustment using trlmmer ADJ
—
A suitable measuring instrument is
a VSC analogue meter, part no. 326 893
- A digital display device can also
be connected giving:
= 24xfD at ~D~{AX 50Hz or 60Hz
~FM = l2XfD at tDI4AX=lOOHz or 120Hz
~FM = GXfD at fD~~<=200Hz or 240Hz
Such a suitable digital meter would
be
a 322 unit, part no. 326 884
