CHAPTER 3 Settings and Measurement
Setting Description
(3) Scaling /1000000, /1000, ×1, ×1000, ×1000000
Sets the scaling factor for a calculation result.
<Example>
In the case of calculation result = 0.001 In the case of calculation result = 1000
Calculation result ×1 = 0.001 Calculation result ×1 = 1000
Calculation result ×1000 = 1 Calculation result / 1000 = 1
Calculation result ×1000000 = 1000 Calculation result / 1000000 = 0.001
Operations span
(4) Upper/Lower limits Sets the upper and lower limits of values of a span in which a waveform should be displayed.
The setting value is in reference to a calculation result.
(5) Dec pt Sets the decimal point position for a span setting.
(6) Scaling setting Selects the unit after conversion.
The unit displayed here is the unit selected in the "Unit select".
When using the unit not displayed here, set any character in the “Arbitrary unit”. Also, the
contents set here is displayed in the “Arbitrary unit”.
(7) Select Selects the unit which indicates the calculation results.
Cur, Length, Area, Volume, Velocity, Accel, Freq, Mass, Energy, Pressure, Flow , Temp,
Strain, Brightness, Concentration
(8) Unit Sets a unit to be used after conversion.
Arbitrary text consisting of alphabetical characters and numerical values can be set as a unit.
(For the character input, refer to "(8) Character string input" in “3.4 Setting Menus”.)
When “Select Unit” or “Unit” is specied, it is reected in here.
When "Select" or "Choose" is used, the setting is reected in this eld.
•
Calculation results are displayed in volts.
The calculation result for 100 mV + 100 mV is 0.2.
Use Scaling to display this result as 200 mV.
•
If the sampling interval is faster than 500 ms for GS sensor, wireless sensor and remote terminal, the
displayed value of inter-CH calculation on the monitor may differ from the actual captured data.
Logic and Pulse settings
Makes settings related to digital input.
<For Pulse> <For Logic>
(1)-7 Logic/Pulse
This is used to select the processing method for digital input.
Selection item Description
Off Digital input measurement is disabled.
Logic Digital input is processed as logic signals.
Pulse Digital input is processed as pulse signals.
