Function Description

■ Display method: frequency
It measures input signal frequency when it is AC input.
In order to measure frequency normally, input signal, over 10 % F.S. of the rated input range,
should be supplied. Otherwise, it may not be measured normally.
The measurement range differs depending on the decimal point position.
It is available to adjust the high-limit display value gradient correction and exponent of SPAN at
parameter setting.
• Accuracy of frequency measurement: below 1 kHz: F.S. ± 0.1 % rdg ± 2-digit,
from 1 k to 10 kHz: F.S. ± 0.3 % rdg ± 2-digit
■ High-limit display value gradient correction
This function is to correct a gradient of high / low-limit scale value.
And also can be used as correction function of high-limit scale value.
Adjustment range is setting value and multiply current gradient.
• E.g.: To display 5.000 when 20 VDCᜡ for input range 0.00 - 50.00 VDCᜡ

Input value
1. Select input range = 50.0, decimal point position = 0.000 for measurement input in Parameter 1.
2. It has to be 12.500 at high-limit scale for 50 VDCᜡ in order to display 5.000 for 20 VDCᜡ.
But it is disable due to setting range is 9.999.
3. In this case, set as high-limit display value gradient correction × high-limit scale = 12.500.
• E.g.: To display -160.0 when -80 mA for input range -200 - 200 mA

1. Select input type = -DC, input range = -200, decimal point position = 000.0 for measurement
input in Parameter 1.
2. If set to display -80 mA as -160.0, the low-limit scale value ×high-limit display value gradient
correction at -200 mA must be -400.0. But it is disable due to setting range is 9.999.
3. In this case, set as high-limit display value gradient correction × high-limit scale = 400.0 and
high-limit display value gradient correction × low-limit scale = -400.0.
• If the low-limit scale is set first set the high-limit scale = - (low-limit scale).
If the high-limit scale is set first set the low-limit scale = - (high-limit scale).
■ High / Low-limit scale value
This function is to display setting of particular high / low-limit value in order to display high /
low-limit value of measured input.
If measured inputs are a and b and particular values are A and B, it will display a = A, b = B as
below graphs.
• When changing input range, it is changed automatically as factory default display range of
the input range.

• In case of DC voltage / current input model and using minus input,

■ Zero adjustment

It adjusts the display value of the optional configured input value as zero by force.
Zero point error can be adjusted with 3 ways as below.
1. Direct input correction value at low-limit display value deviation correction parameter.
2. Press the [◀] + [▲] keys for 3 sec in RUN mode.
3. Set the external input terminal parameter to ZERO and short the Hold / Zero terminal.

■ Error correction
It corrects display value error of measured input.
Display value = (Measured value × High-limit display value gradient correction)
+ Low-limit display value deviation correction
• E.g.: When the input range 0 to 500 VDCᜡ and the display range is 0 to 500.0
If the low-limit display value is 1.2 to 0 VDCᜡ input, set -12 as deviation correction value to
display 0.0 by adjusting offset of the low-limit display value.
The display value to 500 VDCᜡ measured input varies by adjusting the offset of low-limit
display value.
If this display value is 501.0, calculate 500.0 / 501.0 (desired display value / the display value),
and set the 0.998 correction value as the high-limit display value gradient correction parameter
to display 500.0 by adjusting gradient of high-limit value.
■ Startup compensation time
This time function limits the operation of an output until the measured input (overvoltage
or inrush current) is stable at moment of power on. All outputs are OFF during startup
compensation time setting after power is applied.
■ Display cycle
In some applications the measured input may fluctuate which in turn causes the display to
fluctuate.
By adjusting the display cycle delay function time the operator can adjust the display time.
For example, if the operator sets the display cycle time to 4 sec, the display value displayed
will be the average input value over 4 sec and also will show any changes if any every 4 sec.
■ Max. / Min. peak value
It monitors max./min. peak value of display value based on the current displays value and then
displays the data at the parameters. When pressing the front direction keys at the same time
for over 1 sec at the parameters, the monitored data is initialized.
Set the delay time at peak monitoring delay time parameter in order to prevent malfunction
caused by initial overcurrent or overvoltage, when monitoring the peak value.
