Span Check Mode
You can switch the output current between 20 mA and  mA (or 20 mA and 0 mA) using
just the %STEP keys.
When you hold down %STEP▲ or %STEP▼ for 1 second or longer, "SPAN" appears, and
the CA0 enters into span check mode.
In this mode, the output switches to 100% when you press %STEP▲ and to 0% when you
press %STEP▼.
