It is usually thought that a DC inductive load is difficult to switch on and off when compared to a
resistive load. However, the use of an appropriate spark killer enhances the DC inductive load to
almost the same performance as that for a resistive load.

However, the monitor unit displays a value even lower than the minimum value.
0 When external equipment such as a recorder is connected, its load resistance should
be 10kilohms or larger.
* The analog output terminal (AO) should never be shorted with an other terminal so
as to prevent failures.
0 The wires should be asshort aspossible soasnot to be affected by noise, and should
be separated as much aspossible from noise sources such asstrong current carrying
wires.
