Any Sensor Measurement Parameters
Any sensor measurement supports DCV, 2WR, 4WR and FREQ sensors. With the any
sensor measurement function, you can easily convert the measured quantity
(pressure, flow, temperature, etc.) to quantity that is easy to measure (voltage,
resistance, etc.). After inputting the response curve, the instrument converts and
amends the data according to the internal arithmetic to obtain the physical quantity
measured. Users can edit and modify the display unit of the measured physical
quantity at will. The parameters for the any sensor measurement function are as
shown in Table 2-1. Wherein, the integration time and AC filter are introduced in the
preceding section and this section introduces the configuration methods of the other
parameters.
1 Select the sensor type
Enter the first step of the channel configuration guide, select the desired
channel number and function (SENSOR), use the up/down direction keys to
select Type and use the left/right direction keys to select the desired type (DCV,
DCI, 2WR, 4WR or FREQ).
2 Set the unit
Use the up/down direction keys to select Unit and use the left/right direction
keys to select the desired unit (°, ℃, % , ℉ , Ω o r K ).
You can also define a unit. Select “User” and press OK to enter the filename
input interface. Input the desired unit and press OK. The length of user-defined
unit cannot exceed 3 characters.
3 Configure the arithmetic curve
Use the up/down direction keys to select Scaling and “Ax^2+Bx+C” is
displayed by default. Press OK to open the configuration list interface. The
arithmetic between the first start value and the second start value conforms to
the first fitting function, the arithmetic between the second start value and the
third start value conforms to the second fitting function, ……, from the last start
value on, the arithmetic conforms to the last fitting function.
 Add
This menu is used to add the start value and fitting function. Press this
softkey to open the any sensor configuration interface.
Start Value: use the up/down direction keys to select Start and use the
numeric keyboard to input the desired value between -1E+15 and 1E+15.
Fitting Function Coefficients: use the up/down direction keys to select
A, B and C respectively and use the numeric keyboard to input the desired
values between -1E+15 and 1E+15.
