5. Use
keys to enter the data. Use
key to save the data and press
key to
cancel the current data.
6. Press
Shift
+
for percent math operation and the present percent value is displayed in the
primary display and the current measurement result is displayed in the secondary display.
Notes:
1. The setup value will be lost after shut down in method 1; the last setup value will be saved after
restart in method 2.
2. The default unit of the voltage is V, the resistance is Ω.
3.10.4 mX+b
The calculation of reading X on screen is performed as follows:
Where,
X is the normal display reading on screen
m and b is the user-entered value
Y is the displayed result
Application method:
To set the reference impedance, perform the following steps:
Method 1:
1. Press
Shift
+
key to enter into the mX+b math function. The Y value is displayed in the
primary display and the X value is displayed in the secondary display.
2. Press
key at the first time, the value is displayed; press
key again, the b value is
displayed.
3. Press
key to enter into the edit interface when displaying the m value and b value.
4. Use
keys to enter the data. Use
key to save the data and press
key to
cancel the current data.
3.10.5 Max/Min data statistics
The math operation of Max/Min (Maximum/Minimum) is used for storing the maximum value, minimum
value, average value and reading numbers during measurement.
When enabling this function, the Min/Max operation will enable the MnMx annunciator and start to collect
all kinds of statistical figures for readings being displayed. When storing a new minimum value or
maximum value, the instrument will beeps (if beeper function is enabled) one time and open the
corresponding Max or Min annunciator. The multimeter calculates the average values of all readings and
records the measured reading numbers since the Min/Max operation is enabled.
Collected statistical figures including:
Max— the maximum reading since Min/Max operation is enabled
Min—the minimum reading since Min/Max operation is enabled
Avg—the average value of all readings since Min/Max operation is enabled
Num—the measured reading numbers since Min/Max operation is enabled
