If the channel using the scaling function is removed from the scan list, the scaling
function of the channel will be disabled but the scaling coefficients will not be reset.
When the channel is added into the scan list again (without changing the
measurement function), the scaling function will be enabled and the scaling
coefficients remain unchanged.
For a channel using the scaling function, when it is in single-channel monitor, all the
measurement readings are scaling readings.
1 Enable Scaling Configuration
Enter the scaling configuration interface and Scaling is selected by default. You
can use the left/right direction keys to select “ON”. At this point, the fitting
function, coefficients and unit are displayed on the interface.
2 Set the 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. The range is from -1E+15 to
1E+15 and the default is 0. The fitting function defined is displayed in Fitting.
3 Set x1
Use the up/down direction keys to select x1 and press Curr Value to acquire
the current reading as x1. You also can set x1 by using numeric keyboard.
4 Set the Unit
Set the unit of the measurement result. Use the up/down direction keys to select
Unit and then press OK to enter the filename input interface. Input the desired
unit and press OK. The length of user-defined units cannot exceed 3 bytes. You
can use direction keys to select C, F and O respectively and then press and hold
the OK key to enter ℃, ℉ and °.

3
), M (10
6
), G (10

), T (10
12
) and P (10
15
).
 Number: use the left/right direction keys to move the cursor to the number
bit and use the numeric keyboard to input the desired value.
