5.3 Data Lists and Default Settings
5.4.5 Method of Setting Linearization Data
The linearization function means a function that changes the slope of straight
lines in the relationship between the input and indication by correcting the rela-
tions at arbitrary points.
Linearization data are set using the input value (indicated
value before correction) and the output value (indicated value after correction) at
each arbitrary point.
Note: The setup conditions are N-1 < N-2 … N-15 < N-16.
6. Control Functions
6.1 Hold Function
The Hold function temporarily retains the indication. The hold function is enabled
by shortcircuiting the HOLD and COM terminals or setting both terminals to the same
voltage level. As a result the display unit retains the indication given at that moment.
6.2 Digital Zero Function
The Digital Zero function zeros the indication given at an arbitrary timing.
Thereafter, the function shows the amount of change from the point of zero-
ing. However, this function serves as an indication resetting function for a
frequency measuring unit. Thus, the Digital Zero function can be used to reset
the indication when there is no input signal at all.
Note that, the on/off control of the Digital Zero function can be achieved by
means of terminal control or front panel keys. In the case of terminal control,
the Digital Zero function is turned on by shortcircuiting the DZ and COM termi-
nals or setting both terminals to the same voltage level. The indication at that
moment is zeroed. In the case of control with the front panel keys, hold down
the Mode key and press the Increment key for about 1 second to zero the indi-
cation at that moment.
Note: Operation with the control terminals takes priority over operation
with the front panel keys. The Digital Zero function is disabled if
the control terminals are made to go through the off-on-off se-
quence with the function enabled by means of the front panel keys.
6.3 Peak Hold Function
The Peak Hold function retains one of the maximum (peak hold)/minimum
(valley hold)/maximum - minimum (peak-valley hold) values and provides
output for that value. Selection from these values is made using the condition
data. The peak hold function is enabled by shortcircuiting the PH and COM
terminals or setting both terminals to the same voltage level.

Output Function
7.1 Comparison Output Function
The FD5000 series of unit meters is designed so that the two judgment values
HI and LO can be set for the measured (indicated) value to provide the results
of judgment as relay contact output. (This function is effective when the
meter is equipped with a comparison output unit.) For details on the contact
ratings and other specifications, refer to the section “Output Specifications.”
7.2 Analog Output Function
The FD5000 series of unit meters can output an analog signal for an indicated
value (when the meter is equipped with an analog output unit). There are four
output ranges, 0 to 1 V/0 to 10 V/1 to 5 V/4 to 20 mA, from which a selection
can be made using the condition data. In addition, the analog output of the
FD5000 series allows for arbitrary output scaling. This scaling can be achieved
by setting the indication value for an output of the maximum scale value (20
mA for 4–20 mA output range) in the AOHI parameter of the scaling data.
7.3 RS-485 Interface Function
The FD5000 series can be equipped with an RS-485 interface (when the
meter is provided with an RS-485 unit). For details on the RS-485 function,
see the separate manual on communication functions.
7.4 RS-232C Interface Function
The FD5000 series can be equipped with an RS-232C interface (when the
meter is provided with an RS-232C unit). For details on the RS-232C
function, see the separate manual on communication functions.
