Make sure not to greatly vary the input signal when using the comparator
function. Depending on the input signal used for determination, the instrument
may display error codes (i.e. overrange) and this will change the output relays
as follows. When using the output relay as a control signal, make sure to match
these control signals with other equipments to eliminate erroneuous control.

oL (over range)
oF (over flow)
