Output Setting Keys
Set the output value of a source function. Each pair of
▲
and
▼
keys
corresponds to each digit of the reading, thus increasing/decreasing
the digit in units of 1s. Increasing the digit from 9 or decreasing it from
0 causes the digit to overflow or underflow, allowing you to set the out-
put value without interruption. Holding down the
▲
or
▼
key continu-
ously changes the digit in question.
If your choice is the 4–20 mA function, see Section 4.2, “Sourcing DC
Voltage, DC Current or SINK Current Signal,” for further details. Note
that
▲
and
▼
keys are also used in the following ways:
• The
▲
and
▼
keys labeled
n and m serve as keys for setting the
variables
n and m when you have selected the divided output func-
tion (
n/m). (See Section 4.6, “Divided Output Function (n/m),” for
further details.)
• The
▲
and
▼
keys labeled MEM NO., SAVE and READ serve as
keys for working with the memory when you have selected the
memory function. (See Chapter 6, “Memory Function,” for further
details.)
19 CLEAR Key
Initializes the output setpoint, causing the on-screen reading to revert
to 0000 for functions other than PULSE and 20 mA SINK, though the
number of digits depends on function selected. This key serves as a
key for clearing the memory when the memory function is selected.
